Reserve Power/AC Wiring for Three or More Cabinets (Floor Mount)

Floor-mounted systems with three or more cabinets require a Conduit Connection Box (RCCB) to
connect reserve power cabling and AC power cabling to the system. Only a qualified electrician
can install cabling between the reserve power source and AC power cabling to the conduit
connection box. All other steps required to install reserve power, including installation of the
Battery Distribution Box (RBDB), can be accomplished by the normal system installer.
➤ To connect reserve power to floor-mounted systems with three or more cabinets
See Figures 5-23
1. Make sure that the Conduit Connection Box is installed on the bottom cabinet. The box can be
installed by the regular system installer.
2. Have a licensed electrician install conduit and battery cabling to the Conduit Connection Box
and local electrical codes. The remaining steps in this procedure can be performed by the
regular system installer.
3. Install the Battery Distribution Box on the second cabinet (the cabinet directly above the
bottom cabinet).
4. Plug the two Conduit Connection Box cables (coming from the left side of the RCCB box)
into the Battery Distribution Box.
Important!
5. Connect RBTC1A-1.5 and RBTC2A-1.7 cables from the (RBDB or RBDB2) Battery
Distribution Box to the BATT +/- receptacle of individual power supplies (6 RBTC1A-1.5
cables come with each RBDB distribution box). RBTC2A-1.7 is a longer cable, required for
the seventh cabinet. It must be special ordered with part number RCTC1A-1.7M.
6. To test reserve power operation, turn off the system AC power circuit breaker with power
supply On/Off switches in the On position. The system should continue to operate without
interruption.

and 5-26~5-28 and follow these steps:
The cabinets must be connected to the (live) AC power source, and the power supply
On/Off switches set to On prior to the final step of connecting the reserve power
batteries to the power supplies via the BATT +/- receptacle. If the batteries are
connected after AC power is lost, reserve power will not function.
