Mains Power Up 

1)

 

With no external connections made to the PSU, connect the mains input wires to the terminal block, 

ensuring that the mains isolator (disconnect device) is open

. Fasten wiring in place with cable tie to 

saddle. 

Note: Equipment must be earthed. 

2)

 

Apply mains input. Confirm that all LED indicators flash on briefly proving integrity of indicating circuits. 

Ensure that the green Mains LED then stays illuminated and that the yellow Fault LED flashes after 

approximately 3 s (indicating a disconnected battery). 

3)

 

Disconnect the mains power. 

Load Output and Remote Signalling 

4)

 

Connect the EPS and GEN PSU Fault outputs to the appropriate inputs of control equipment if remote fault 

monitoring is required. 

5)

 

Connect the load (output) wiring as shown in Figure. 3. Cable tie to saddle provided (adjacent to exit 

hole).

Re-apply mains. Verify that the green Mains LED illuminates and the yellow Fault LED flashes after 

approximately 3 s (disconnected battery). 

7)

 

If connected, verify that the EPS Fault monitor shows a 

closed 

contact and the GEN PSU Fault monitor 

shows an 

open 

contact. 

8)

 

Perform a full functional test of system including full alarm condition. 

9)

 

For 17 Ah batteries fit the link to the Battery select pins as indicated, for 7 or 2.1 Ah batteries remove link, 

as shown in Figure 3.

Mount the appropriate batteries as shown above. Where a dual box solution is used all cabling between 

the two boxes should be routed to use separate case entry/exit holes from other cabling and use suitable 

bushes to protect the cables
