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
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.
