To fit the PSU7A assembly (A) into a remote battery enclosure, 
proceed as follows:

1

Place a nylon spacer (B) over each of the four stand-offs (C) 
on the rear wall of the enclosure. Screw an M4 X 16 SEM 
screw (D) approximately 2 or 3 rotations into each stand-off. 
DO NOT FULLY TIGHTEN. The PSU7A assembly must be 
orientated so that the mains connector is to the upper left. 
Position the PSU7A over the screws, then tighten them to 
secure the assembly in place.

Procedure for Fitting PSU kit into a Remote 
Battery/PSU Enclosure

IMPORTANT NOTE when using 130Ah 
Battery Back Up....

To ensure correct operation of the PSU7A when used with 
130Ah back up batteries, two remote enclosures MUST be 
used. The PSU7A must be installed in one enclosure and ALL 
the batteries must be installed in the other enclosure. For 
further details when using the 130Ah batteries, refer to 
instruction sheet 997-270-000-X.

The PSU output is configured using jumper links; the three 
valid options are: no links fitted, one or both fitted. Refer to 
the table below left for guidance on the fitting of jumper links 
on the PSU PCB in the appropriate position. Jumper 
headers CON 2 and CON 3 are located to the left of the 
thermistor wiring connectors when the PSU is orientated 
with the wiring connectors at the bottom (as illustrated).

CAUTION: Incorrect fitting of the link(s) or failing to fit both 

links with 78Ah or 130Ah backup batteries, will 
reduce the power available to the panel during 
quiescent operation or invalidate the battery 
charging requirement of EN54 Part 4.

IMPORTANT NOTE

If the PSU7A is used in the remote battery 
enclosure the enclosure must be mounted in close 
association with the cie. Power cables must be 
routed through steel conduit connecting the two 
enclosures.
