Preface

About this guide This quick start guide is for quick installation or an overview of the SPD. Thus only the three-phase star AC connection with SPD is described in this guide. User shall refer to the main SPD user manual (Emerson file No. 03370500080) for more details about the other AC connections.

SPD Introduction The Flexi Power Rectifier (FPRA, Emerson part number AA25020L) is an up to 6kW output power AC rectifier package. The Surge Protect Discharge (SPD, Emerson part number AA25130L) is used to prevent the damages to the FPRA that caused by input over voltage or surge. The SPD consists of three same OVP modules that used between live cables and neutral cable from the AC mains; one OVP module that used between the neutral cable from the AC mains and the earth; and one remote signaling contact.

SPD installation 13

1.1 Detach the cable strain-relief from the chassis by loosening the screw ‘A’ in Figure 1.

1.2 Detach the AC ground clamp and SPD ground clamp from the chassis by loosening the screws ‘B’ and C‘ in Figure 1.

1.3 Fit the PE cable from the AC mains into the AC ground clamp. 1.4 Fit the live cables from the AC mains and the bare end of L line short

links into the terminals ‘L1’, ‘L2’ and ‘L3’ on the SPD respectively referring to the diagram of 3Y AC connection in Table 2 and Table 3 (see Figure 2).

1.5 Fit the neutral cable from the AC mains and the flat end of N short link into terminal ‘N’ on the SPD referring to the diagram of 3Y AC connection in Table 2 and Table 3 (see Figure 2).

1.6 Fit the ground cable link into the SPD ground clamp, and the other end

into the SPD ground terminal on the SPD referring to the diagram of 3Y AC connection in Table 2 and Table 3.


SPD installation 14

1.7 Secure the AC ground clamp back into its position on the chassis,

tightening the screw ‘B’ (refer to Figure 1). 1.8 Secure the SPD ground clamp back into its position on the chassis,

tightening the screw ‘C’ in Figure 1. 1.9 If required, detach the AC terminal block from the chassis by loosening

screws ‘D’ and ‘E’ in Figure 1. This will provide a better view of the AC terminal block connections.

1.10 Connect the L1, L2 and L3 line short links to terminals ‘6’, ‘5’, ‘4’ on the AC terminal block respectively referring to the diagram of 3Y AC connection in Table 2 and Table 3 (see Figure 3).

1.11 Connect the N line short link to terminal ‘2’ on the AC terminal block referring to the diagram of 3Y AC connection in Table 2 and Table 3 (see Figure 3).

1.12 Connect the SPD sense cable to the SPD remote signaling contact. 1.13 Secure the SPD to the DIN Rail by locating the grounding side bottom

slot of the SPD onto the DIN Rail and pressing down on the SPD until it locks in position.

1.14 Refit AC terminal block if removed from chassis, tightening the screws ‘D’ and ‘E’ in Figure 1.

1.15 Connect the SPD sense cable to the PDA sense connection, and restrain the cable to position ‘F’ on the chassis in Figure 1.

1.16 Restrain the AC cable on the socket by fitting the Strain-relief, tightening the screw ‘A’ in Figure 1.

SPD installation 16

CAUTION: 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 multi-meter to check for wiring continuity. It’s strongly suggested that the insulation test (2.5kV Hi-pot) is carried out.


SPD replacement 17
