POWER SUPPLY TESTS
Disconnect the batteries and make sure that the leads are suitably insulated to avoid a short
condition.
Disconnect the panel supply leads marked 28 V d.c. supply OUT.
Connect the a.c. mains voltage to the terminal block on the switch mode power supply and
perform the following tests.
1.
Check that the voltage at the +28 V d.c. supply output terminals is 28 ± 5V d.c. and
the polarity is correct.
2.
Check that the batteries are disconnected.
Check that the voltage at the BAT output terminals is 27.6 ± 0.2 V d.c.. and that it
drops to 26 V d.c. on full charge.
3.
Make sure that the a.c. mains and batteries are disconnected.
4.
Reconnect the cables in the 28 V output terminals observing the correct polarity of the
supply is maintained.

COMMISSIONING
4.9.1 Preliminary Checks
Commissioning is to be carried out only after successfully completing the installation of the
systems as per the installation instructions.
Prior to the initial power up of the panel the following procedures must be undertaken:
1. Check for any visible signs of damage which may have been caused during the
installation.
2.
Verify that all installation instructions have been adhered to.
3.
Physically check all PCBs are secured in their mountings
4.
Check all ribbon cables are secured and correctly connected.
5.
Check all cable terminations are secured.
All damage and/or faults must be rectified before proceeding.
Using an Ohmmeter
6.
Re-check for continuity of the feed and return of the +ve and -ve legs of each loop.
