Install Reserve Power

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

Floor-mounted systems with three or more cabinets require a Conduit Connection Box (BCCB) to connect reserve power cabling and AC power cabling to the system. Only a qualified electrician can install cabling between the reserve power batteries and AC power cabling to the conduit connection box. All other steps required to install reserve power, including installation of the Battery Distribution Box (BBDB), can be accomplished by the normal system installer.

To connect reserve power to floor-mounted systems with three or more cabinets

See Figures 4-12~4-17and follow these steps:

1.Make sure that the Conduit Connection Box is installed on the bottom base cabinet (see Figure 4-24). 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 per local electrical codes. The remaining steps in this procedure can be performed by the regular system installer (see Figure 4-25).

3.Install the Battery Distribution Box on the second cabinet (the cabinet directly above the bottom cabinet), see Figure 4-24.

4.Plug the two Conduit Connection Box cables (coming from the left side of the BCCB box) into the Battery Distribution Box (BBDB).

Important! 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.

5.Connect cables from the (BBDB) Battery Distribution Box to the BATT +/- receptacle of individual power supplies. BBTC2A-2M cables come with each BBDB distribution box (see Figure 4-12).

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.

Note AC/DC wiring and conduit must be installed by a licensed electrician per local electrical code (conduit trade size is 1/2 inch).

See “Install Reserve Power” on page 4-29for battery specifications and wiring guidelines.
