3. Select a terminal block. Either terminal block on the back of the 12000E may
be used to power the chassis; only one terminal block is required for
operational purposes. The two terminal blocks on the 12000E are independent
feeds. Chassis power is supplied by only one terminal block at a time; the
second supply is a backup. Likewise, the two terminal blocks do not
load-share. Each terminal block must be supplied with adequate amperage to
run the chassis independently.
CAUTION:
Two identical terminal blocks are provided on the 12000E chassis to allow
for redundant 48V DC power sources. Each power source to be connected
with the 12000E must be equipped with a disconnect device such as an
On/Off switch, or, an appropriately rated circuit breaker must be installed
on each power circuit to be used. Hazardous voltages will not be removed
from the 12000E until all power sources have been either turned off or
disconnected from the chassis.
