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)
(shown in
Figure 7-22 and 7-23 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 7-12 ~ 7-15 and follow these steps:
1. Make sure that the Conduit Connection Box is installed on the bottom base cabinet (see Figure
7-22 ). 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 7-23 ).
3. Install the Battery Distribution Box on the second cabinet (the cabinet directly above the
bottom cabinet), see Figure 7-22 .
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 7-12 ).
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 7-26 for battery specifications and wiring guidelines.
Step 6: Install Universal and Processor PCBs
This section provides procedures for the installation of DK424i processor (or common control)
PCBs.
The DK424i system Base and Expansion Cabinets are shipped empty. PCBs are not installed at the
factory. Universal PCBs must be placed according to the configuration information obtained and
developed in Chapter 6 – DK424i Configuration. Processor PCB installation starts on
Page 7-41 of
this chapter.
♦ Install PCBs only after installing the Base Cabinet and, if applicable, Expansion Cabinets per
the Cabinet Installation section in this chapter.
♦ Be sure the power supply has been tested and the ground has been checked (see “Install Power
Supply” on Page 7-6 .
