See Figures 2-11~2-13 and follow these steps:
1. Make sure that the Conduit Connection Box is installed on the bottom base cabinet (see
Figure 2-20). 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
3. Install the Battery Distribution Box on the second cabinet (the cabinet directly above the
bottom cabinet), see
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 2-11).
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.
