Energize/Startup
Procedures
CAUTION: Fire Hazard
!
Before energizing, confirm that all hardware
is installed as shown on the Installation
page. Stacking battery terminal hardware in
any other order can overheat the terminals.
Pre-startup Procedures:
1.
Double-check all wiring connections.
2.
Inspect the enclosure to ensure no
debris or tools have been left inside.
3.
Disconnect all AC loads at the backup
(or critical) load panel.
4.
Disconnect the AC input feed to
the GSLC at the source.
To energize or start the OutBack devices:
1.
Using a digital voltmeter (DVM), verify 48 Vdc
on the DC input terminals by placing the DVM leads
1a
1b
on
and
.
Confirm that the battery voltage is correct for the
inverter and charge controller models.
Confirm the polarity.
CAUTION: Equipment Damage
!
Incorrect polarity will damage the equipment.

2.
Turn on (close) the GFDI circuit breaker.
3.
Verify that the PV input for each charge controller
is in the correct range of open-circuit voltage and
confirm the polarity by:

8.
Verify 120 Vac on the AC Output L2 TBB
and
9.
Verify 240 Vac between the AC Output TBBs by placing the DVM leads on
5
10. Turn on (close) the AC output circuit breakers.
11. Start the generator if appropriate. Verify 120/240 Vac on the terminals of the AC input sources.
12. Turn on the AC input feed to the GSLC at the source.
11. Verify 120 Vac on the GRID IN L1 TBB by placing the DVM leads on
4b
3c
12. Verify 120 Vac on the GRID IN L2 TBB
and
13. Verify 240 Vac between the GRID IN TBBs by placing the DVM leads on
14. Verify 120 Vac on the GEN IN L1 TBB by placing the DVM leads on
5b

15. Verify 120 Vac on the GEN IN L2 TBB
and
.
16. Verify 240 Vac between the GEN IN TBBs by placing the DVM leads on
6
17. Turn on (close) the AC input circuit breakers.
18. Turn on the AC disconnects at the backup (or critical) load panel and test the loads.

during operation. Do not
remove the cover during
operation or touch any internal
parts. Be sure to allow them
sufficient time to cool down
before attempting to perform any
maintenance.
WARNING: Lethal Voltage
Review the system configuration to identify all
possible sources of energy. Ensure ALL
sources of power are disconnected before
performing any installation or maintenance on
this equipment. Confirm that the terminals are
de-energized using a validated voltmeter
(rated for a minimum 1000 Vac and 1000 Vdc)
to verify the de-energized condition.
WARNING: Lethal Voltage
The numbered steps will remove power from
the inverter and charge controllers. However,
sources of energy may still be present inside
the GSLC and other locations. To ensure
absolute safety, disconnect ALL power
connections at the source.
