INSTALLATION BETWEEN INVERTER AND ALTERNATING
SOURCE (CONFIGURATION C)
For installation between inverter (default) and another power
supply (dominant), such as the output from a prior powercord/
generator transfer switch, connect the inverter to terminals 7
and 8, and connect the other power supply to 5 and 6. Output
terminals always remain the same. These connections will al-
low any other supply to dominate the inverter, and the inverter
output will pass through the normally closed contacts of the
switch. This allows the inverter to operate only in the absence
of the other power supplies, which is ideal for inverters. Set
the timer delay bypass switch of the inverter/alternate source
transfer switch to the ON position. See Diagram 2.
INSTALLATION IN HYBRID SYSTEM FOR DESIGNATED
CIRCUITS (CONFIGURATION D)
The ITS-30R can be installed between inverter (default)
and a circuit panel supplied by a larger amp alternating
power supply (dominant). Connect the inverter to termi-
nals 7 and 8, and connect the 30 amp branch circuit to 5
and 6. Connect the designated circuit panel to the output
terminals. The inverter will only supply the load in the ab-
sence of the 50 amp power supply, in which case, only the
load designated to the 30 amp branch circuit is supplied.
The timer delay bypass switch on the ITS-30R should be
in the ON position.
