AC POWER CONNECTION
Employ a dedicated 117VAC 15 AMP circuit, with a
third-wire ground, supplied to a standard electrical
outlet (NEMA 5-15R) for the AC power connection.
AC power connection is illustrated in Figure 3-2
shown below.
•
A plug-in power line surge protector should be
installed between the power cord and the AC outlet.
•
Do not connect the AC power cord until the
installation has been checked.
•
To apply AC power, connect the power cord to the
electrical outlet.
BATTERY BACK-UP
The common equipment provides an interface
connector for the connection of an optional external
battery assembly. This assembly is available
separately as a kit.
CAUTION
Be sure that the AC power cord is connected
to the electrical outlet before connecting the
external battery assembly to the common
equipment interface connector. This ensures
that internal protection circuitry is operating to
prevent damage that could result from
improper connection.
•
When charged to full potential, the optional Comdial
model BBU01 external battery assembly provides a
minimum of one hour of operation should the AC
power to the system be interrupted. No calls will be
dropped when an AC power failure causes the
system to automatically switch over to BBU01
operation
The BBU01 external battery assembly may include
batteries from either of the following suppliers:
- Model PS-1265 from Power-Sonic Corporation,
Redwood City CA, 94032.
- Model EP1265-26 from Elpower Corporation,
Santa Anna, CA 92704
•
During AC operation, the common equipment
provides re-charging current to maintain the voltage
potential of the external battery assembly at an
operational level.
NOTE: The optional external battery assembly
requires approximately ten (10) hours to
completely re-charge to full potential after it has
been completely discharged and, in some
cases, when initially installed.
SYSTEM GROUNDING
The common equipment cabinet has internal
secondary surge protection on all line ports. In order
for this protection to be effective, the cabinet MUST be
connected to a reliable earth ground such as a metal
cold water pipe or a building frame ground. The
grounding wire must be of #10 or #12 insulated, solid
copper and separate from the three-wire AC line cord.
A ground stud is located on the common equipment
cabinet for this purpose. System grounding is
illustrated in Figure 3-2 on page 3-4.
