3.10 Using The Power Supply
What the power
supply does
Each cabinet in the DXP Plus system has its own power supply. The power
supply pr and – 5 VDC operating power for the circuit boards and – 36
VDC for all of the telephone stations. Each power supply is located in the top
right corner of the respective cabinet (see figure 12 for power supply locations).
Power supply
requirements
For the AC power connection, employ a dedicated 117VAC 15 AMP circuit, with
a third-wire ground, supplied to a standard electrical outlet (NEMA 5-15R).
Remember, this electrical outlet must be located within four feet of the common
equipment cabinet. You must supply two dedicated electrical outlets, each
protected by its own circuit breaker, if you plan to install expansion cabinets.
CAUTION
The dedicated AC circuit for the expansion cabinets must be different from the dedicated AC
circuit that you provide for the main cabinet.
Where
to connect the
power supply
If you install the optional battery back-up assembly, you can use the main
cabinet’s electrical outlet to supply AC power to that assembly’s battery charger.
To provide protection against surges and spikes that may appear on the AC line,
install a plug-in power line surge protector between the AC power cord of the
installed equipment and the AC outlet.
The common equipment cabinet employs a fan-cooled electronic switching power
supply (ensure that the fan can always provide unobstructed air flow for cooling).
During operation, power supplies of this type generate an audible sound from
their switching regulators. This sound is normal and is not an indication that the
power supply is operating improperly.
CAUTION
DO NOT attach or secure the line cord to the surface of the mounting location in any manner.
