101.2 AC Wiring Preparations
If not previously done, remove knockouts for AC Input and AC Output in the LiteGear inverter system and install input
and output conduits per section 100.2
101.3 AC Input Voltage Selection
The battery charger transformer has two input leads:
black = 120VAC
orange = 277VAC
Select proper AC input lead for the application.
Refer to Fig. 102-1.
For
120VAC
input:
• Black – Connect to FT22
• Orange – Remove “push on” connector and cap off using appropriate mechanical
connector
OR
For
277VAC
input:
• Orange – Connect to FT23
• Black - Remove “push on” connector and cap off using appropriate mechanical
connector
101.4 AC Output Voltage Selection
Refer to Fig. 102-2
For
120VAC
output:
• Install 120VAC fuse into holder and install fuse holder in bracket
• Discard 277VAC fuse and install fuse holder in bracket
OR
For
277VAC
output:
• Install 277VAC fuse into holder and install fuse holder in bracket
• Discard 120VAC fuse and install fuse holder in bracket
101.5 AC Output Wattage Selection
Refer to Fig. 102-3
For loads less than
36 Watts
:
• Remove jumper connected between J1 and J2 on the standoff
electronics board
• If load wattage is increased later, then jumper should be reapplied.
Otherwise, unit will fail to provide output voltage.
OR
For loads greater than or equal to
36 Watts
:
• Proceed to Section 102
102. Load Configuration Wiring Options
102.1 AC Input and AC Output Connections
CAUTION:
Torque all terminal block connections to 4.4 to 5.3 in-lb. (0.5 to 0.6 Nm.) Failure to do so may create an
unsafe condition or fire hazard. Only "Normaly ON" or "Normally OFF" or "Externally Switched" loads can be selected.
102.2 “Normally ON” loads
Connect utility and load to appropriate terminal blocks per Fig. 102-1 and ensure the input, output, and chassis are
grounded.
