Application of this manual This manual is regarded as a substitution of the part ‘Make AC connection without the SPD’ (refer to section 3.4 of the ‘Flexi Power Rectifier - Installation Manual’, Emerson File No. 970009475-0000). This manual is based on the present SPD in use. Emerson may change the SPD to a second source in future. However Emerson ensures the compatibility of the new SPD in the FPRB. This manual supports all applications of the SPD that can be used in the FPRB.

Flexi Power Rectifier FPRB Chapter 1 Product Introduction 1.1

General Description The Flexi Power Rectifier (FPRX, Emerson part number AA25020L/ CS7000013.XX for 6kW and AA27540L/ CS7000030.XX for 9kW) is a 6kW or 9kW output power AC rectifier package respectively. The Surge Protective Device (SPD, Emerson part number AA25130L/ CS7000002.XX) is used to prevent damage to the FPRX caused by high input voltages or surge. The SPD consists of three equivalent OVP modules used between live cables and neutral cable from the AC mains; one OVP module used between the neutral cable from the AC mains and the earth; and one remote signaling contact. The SPDs mentioned in this manual are applicable for both 6kW and 9kW system. The SPD used is the same as the one we used in FPRA.

1.2

Main Specification of the SPD The SPD illustrated in this manual is made by ‘Phoenix Contact CO., Ltd’ (model number: VAL-MS 230IT/3+1-FM), or SICHUAN ZHONGGUANG LIGHTNING (model number: ZGG40-385(3+1)). 12 14

Flexi Power Rectifier FPRB The SPD (module name ‘VAL-MS 230IT/3+1-FM’) consists of three equivalent OVP modules used between live cables and neutral cable from the AC mains (module name ‘VAL-MS 230 IT ST’), one OVP module used between the neutral cable from the AC mains and the earth (module name ‘F-MS 12 ST’) and one remote signaling contact (module name ‘VAL-MS 230IT…-FM’) (see Figure 1). The four OVP modules and the remote signaling contact are all installed on the SPD base and can be removed from the base. This structure leads to easier configuration and replacement of the OVP modules (see Figure 2).

Failure Detection

If any OVP module has been damaged, Emerson will provide the user with the individual OVP module but not the whole SPD for replacement. In the event that any one of the four OVP modules is damaged, the PDA will send alarm signal via the LCD. After opening the rear top cover of the PDA (refer to section 3.4 of the ‘Flexi Power Rectifier – Installation Manual’, Emerson File No. 970-009475-0000), the user can confirm which OVP module is in failure.



Failure Indication If the window is transparent, the OVP is OK; if the window is red, the OVP is damaged and should be replaced in time (see Figure 6).

The AC power supply must be switched off prior to accessing the AC cable.

 This manual concentrates on the AC connection with the SPD, and omits the steps prior to the SPD installation, i.e. the AC terminal block configuration, etc. The user should refer to ‘Flexi Power Rectifier – Installation Manual’ (Emerson File No. 970-009475-0000) for the relevant previous steps.  The colors of the AC mains wire used in this manual are for illustration purpose only. However, the user should verify the AC mains referring to the color-coding in the respective field or country of application.

3.1.2

Configure the Terminal Block

Verify the AC power system types in field, and make sure the corresponding bridge configuration is used.

The AC terminal block has been already configured for 3-phase star AC mains before the shipment. Therefore the user has to change the AC terminal block configuration if required referring to the actual AC type in field.

Insert the bridges and screws (provided as accessories) to the corresponding slots on top of the AC terminal block referring to the AC CABLE CONNECTION CHART located on the chassis (and reproduced in Figure 8). Secure the screws with a flat screwdriver, tightening to 0.8Nm.

Figure 8 – The AC cable connection chart There are three AC power system types (see above Figure), and thus three AC configurations of the AC terminal block.


Page 27 of 45


Single-phase (1Φ) and Two-phase (2Φ ) configuration For Single- phase AC system, use two 3-pole bridges to short the terminals 1, 2, 3 and 4, 5, 6 respectively on the AC terminal block (see Figure 9)

Figure 9 – AC terminal block configuration – 1Φ and 2Φ Configuration 

3- phase delta (3Δ) configuration For 3-phase delta AC system, use three 2-pole bridges to short the terminals 1, 2 and 3, 4 and 5, 6 respectively on the AC terminal block (see Figure 10 )

Figure 10 – AC terminal block configuration – 3Δ


Page 28 of 45


3- phase star (3Y) configuration For 3-phase star AC system, use one 3-pole bridges to short the terminals 1, 2, 3 on the AC terminal block (see Figure 11)

 The terminal marks in Figure 12 are in accordance with the actual SPD and AC terminal block.  Use the indicated L or N short link for the AC mains as shown in Figure 12 and Table 7 referring to labels on the short links.  The terminals 1, 2, 3 on the AC terminal block should be shorted before the connection. Refer to section 3.4 in Flexi Power Rectifier – Installation Manual (Emerson file No.970-009475-0000) for details. 3.1.3.1

Detach the cable strain-relief from the chassis by loosening the screw ‘C’ in Figure 7 with a TORX screwdriver (T20). Insert the AC mains cable on the strain relief.

3.1.3.2

Detach the AC ground clamp and SPD ground clamp from the chassis by loosening the screws ‘A’ and B ‘with a TORX screwdriver (T20).

3.1.3.3

Prepare the AC mains of 3-phase star as per Table 6.

3.1.3.4

Assemble the Link cables, the AC mains cable, the SPD sensor cable and the SPD grounding cable into the SPD. Refer to Figure 13

Rotate the N link cable 90 degrees either clockwise or counter clockwise when assembling the SPD on the FPRA due to the smaller slot of the terminal block. Refer to Figure 17 - Special Instruction for N Link Cable Installation

 After installation of the SPD kit has been completed, the installer should check the installation against the steps outlined within this document, supported by a multimeter to check for wiring continuity.  It’s strongly suggested that the insulation test (2.5kV Hi-pot) is carried out.

 The terminal marks in Figure 19 are in accordance with the actual SPD and AC terminal block.  Use the indicated L or N short link for the AC mains as shown in Figure 19 and Table 7 referring to labels on the short links.  The terminals 1,2,3 and 4,5,6 on the AC terminal block should be shorted respectively before the connection. Refer to section 3.4 in Flexi Power Rectifier – Installation Manual (Emerson file No.970-009475-0000) for details.

Perform the same procedure in preparing the AC cables SPD grounding cables and the SPD sense cables.

3.1.4.2

As indicated in Figure 19 and Table 7, the SPD terminals L1, L2 and L3 have to be paralleled by the SPD jumper (see Figure 20).

 The user should loosen the three terminal clamps of L1, L2 and L3, and hold the SPD upside down. Thus the SPD jumper can be easily inserted into the parallel clamps.  The jumper should be fixed in the SPD together with the live cables of the AC mains and L line short links.

Flexi Power Rectifier FPRB 3.2 Replace the SPD

The AC power supply must be switched off prior to accessing the SPD.

 Ask Emerson Network Power service people for help if any OVP module has been damaged. Emerson will provide the user with the individual OVP module but not the whole SPD for replacement.  The user shall only replace the damaged OVP module of the SPD without removing the whole SPD from the PDA chassis. The user can verify which OVP module has been damaged Referring to section Properties. 3.2.1 Hold the two sides of the damaged OVP module and pull it out from the SPD base (see Figure 28)

Figure 28 – Removing the damaged OVP module from the SPD

3.2.2

The SPD base is designed such that the two kinds of OVP modules cannot be mixed when installing onto it (see Figure 29).

Figure 29 – The OVP module and the SPD base

3.2.3

Fit the new module into its position on the SPD base (see Figure 30).
