If your load bank is
equipped with Metering,
Automatic Mode or
Regenerative Mode options,
you will have to install
current transformers on
your power cable.
• For metering mode,
install the current
transformers on the load
bank leg of your power
system (see “Figure 13
Current Transformer
placement for Metering”
on page 12.)
• For Automatic/
Regenerative Mode,
install the current
transformers on the power
source leg (see “Figure 14
Current Transformer
placement for Auto/
Regen. Mode” on page
12.)
Orient the current
transformers so that the XI or
HI on each ring is facing the
power source (see Figure 11
CT Orientation.)
When the current
transformers are installed,
connect them to the load
bank by connecting the
white wire of the current
transformer on Phase A to
TB-CT 1 and the black wire
to TB-CT 2. If a second
current transformer is
installed on Phase C, connect
its white wire to TB-CT 3
and its black wire to TB-CT
4 (see Figure 12 TB-CT.)
