Proc e dure s
Pre -st a rt up Proc e dure s:
1. Double-check all wiring connections.
2. Inspect the enclosure to ensure no
tools or debris has 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.

WARN I N G: Burn H a za rd
Internal parts can become hot
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.
WARN I N G: Le t ha l V olt a ge
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.
WARN I N G: Le t ha l V olt a ge
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.
