Terminal Power
Source
The terminal is powered by an external AC/DC power pack. When you have
finished installing the necessary cards and/or optional devices, you are ready to
connect the terminal to the power source.
The terminal requires connection to a power outlet with a dedicated circuit or an
uninterruptible power supply (UPS). If other devices are plugged into the same
circuit, the terminal can potentially experience power fluctuations that might cause
it to malfunction. The terminal shuts down automatically once power source is
removed.

2 Plug in power supply to the power connection port on the base module.
3 Plug the AC power cord into a wall outlet or power surge protector.
4 Close cable cover (optional).
WARNING
Do not connect the terminal to the power supply until all peripherals are attached.
Using an incorrectly rated power supply can damage the unit or cause it not to
work properly. Use only a power pack with P/N PWR445-001-01-A. See
Specifications for detailed power supply specifications.
Do not plug the power pack into an outdoor outlet or operate the terminal
outdoors. Disconnecting power during a transaction can also cause unstored
data files to be lost.
NOTE
Verifone recommends installing a power surge protector to protect against
possible damage caused by lightning strikes and electrical surges.
