106.3 Battery Voltage Check
Using a digital volt-ohm meter, check for correct nominal battery voltage between DC Input NEG
and POS wires. Volatge reading should be ±10% of system’s nominal 60Vdc for LG375S, 96Vdc
for LG600S operating voltage.
107. Final Installation Checklist
IMPORTANT: Before proceeding to the System Start-up Procedure (Section 108) complete
the Final Installation Checklist below.
1.
Ensure the LG cabinet is securely fastened to a wall or other structure.
2.
Ensure that the input circuit breaker in the building service panel serving as the AC disconnect to
the LG system is in the
OFF
position.
3.
Check for proper ground connections in the
LG
unit cabinet.
4.
Check for any loose wiring connections in the
LG
unit cabinet.
5.
Check that correct nominal battery voltage (60Vdc for LG375S, 96Vdc for LG600S) is present in
the
LG
unit between the battery’s
NEG
and
POS
end terminals.
6.
Verify AC Input Voltage Selector Jumpers are installed and in the proper position to accept the AC
input line voltage system voltage configuration.
CAUTION: Failure to install the Voltage Selector Jumpers will prevent system operation.
Installing the Voltage Selector Jumpers in the position that does not match the AC input
line voltage will damage the unit, void the warranty and may cause a dangerous or unsafe
condition.
108. System Start-Up Procedure
IMPORTANT: The LG inverter system is a sophisticated electronic backup power supply.
Care must be taken to follow the steps below in their exact sequence. Failure to do so may
result in possible equipment failure.
CAUTION: Familiarize yourself with the shut down procedure in Section 200.1 before proceed-
ing with the LG system Start Up.
1.
Hold S-1 Pre-charge Switch in the on(up) position for 15 seconds then release.
2.
Place battery circuit breaker (CB-1) in the on position.
3.
Apply utility AC power to the system by turning the branch circuit breaker in the main power panel
to the ON position. Place AC output
breakers CB-3 & CB-4 in the on position (if
equipped
).
4.
Observe the LED Status indicators and verify the following:
A)
AC ON
indicator (red LED) is illuminated (indicates AC utility power is available to unit).
B)
CHG ON
indicator (green LED) is illuminated (indicates battery is connected and charger is
operational).
5.
Verify
Normally-On
fixtures or switched fixtures (where applicable) are illiminated (local fixture
switch must be in
ON
position).
109. Manual System Test
Momentarily push
TEST
switch and verify the following:
A) INV ON status indicator (yellow) illuminates (indicates inverter is operational).
B) Normally-On, Normally-Off and Switched fixtures are illuminated (where applicable)
