RPSB power strip. Plug the power strip power
cord into a wall outlet (see Figure 3-1 1).
Note:
Power Supply testing procedures are
provided in the Fault Finding section, which
should be referred to if it is suspected that the
power supply does not work properly.
3.7.2 Wall-Mounted Systems with Three or
More Cabinets
Local electrical codes specify that a maximum of one
or two AC power cords from the system can be
plugged into wall outlets. Systems with three or more
cabinets must be equipped with power strips (RPSBI
or RPSB2) to adhere to this requirement. Each power
strip has three outlets and an AC power cord
(Figure 3-20).
Three-cabinet systems require one power strip, while
four to six-cabinet systems require two or three power
strips depending on local electrical code requirements
pertaining to the number of AC power cords (one or
two) allowed from the system. Refer
recommended power strip placement.
Refer to the following instructions to install AC power
cabling to wall-mounted systems with three or more
cabinets:
1. Make sure all power supply (RPSU280) switches
are in the off position.
2. Secure power strips to applicable cabinets
(Figures 3-20 and 3-23).
3. For AC power cords that will be plugged directly
into a wall outlet: Undo the tie wrap that keeps the
cord coiled. Plug female end of the cord into the
power supply, and plug the male end into the wall
outlet.
4.
For AC power cords that will be plugged into
power strips: Do not undo the tie wrap that keeps
the cord coiled. Plug female end of the cord into
the power supply, and plug the male end into the
power strip. Plug the power strip power cord into a
wall outlet (see Figure 3-1 1).
Note:
Power Supply testing procedures are
provided in the Fault Finding section, which
should be referred to if it is suspected that the
power supply does not work properly.

3.7.3 Floor-Mounted Systems with Three or
UL specifies that floor mounted systems with three or
more cabinets require the installation of a Conduit
Connection Box (RCCBI) to connect AC power
cabling (and reserve power) to the system. Cabling
from the AC power source to the conduit connection
box can only be installed by a licensed electrician
(Figures 3-21 and 3-22).
AC power cabling for floor-mounted systems with
three or more cabinets requires the installation of one
or two power strips (RPSBI), depending on the
number of cabinets installed. Refer to Figure 3-20 for
recommended power strip placement. Use the
following instructions to connect AC power cabling to

floor-mounted systems with three or more cabinets:

Two or four customer-supplied, 12VDC batteries (80
ampere hours maximum) can be connected to the
system as a power failure backup (see Figure 3-26). In
the event of a power failure, the system automatically
switches over to battery power without any interruption
to existing calls or other ndrmal system functions. The
length of time reserve power operates depends on the
system, size and number of batteries provided, and

Make sure that the conduit connection box is
installed on the bottom cabinet (Figures 3-21 and
3-22). The box can be installed by the regular
system installer.
Have a licensed electrician install conduit and
cabling from the AC power source to the conduit
connection box per Figures 3-21 and 3-22 and
local electrical codes. The remaining steps in this
procedure can be performed by the regular
system installer.
Make sure all power supply (RPSU280) switches
are in the off position.
Secure power strips to applicable cabinets
(Figure 3-20).
For each power supply: Plug the female end of the
provided AC power cord into the power supply,
without removing the tie wrap that keeps the cord
coiled. Plug the other end of the cord into a power
strip (Figure 3-20).
Plug power strip power cords into the conduit
connection box.
