Replacing a Power Supply
The below section describes how to upgrade or replace a power supply module. The replacement power supply
module will contain both power supplies and the mounting bracket. The P1520 uses one fan cooled power
supply.
1.
Power down unit via software or On/Off button
2.
Important: UNPLUG power cord from wall or terminal
3.
Turn terminal on side or face down (make sure the countertop is clear of objects to avoid touch screen
damage). Remove screw holding the power supply to the base. (see below)
4.
Gently slide the power supply module out of the base and set off to the side of the unit.
5.
Disconnect the power supply module ( metal bracket) at the connector located next to the
power supply. Below is shown the entire power supply and cable assembly.
