enclosures.
Procedure for Fitting PSU kit into a Remote
Battery/PSU Enclosure
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.
2 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.
