5.2. EU Power Supply Replacement

The power supply for the EU is a field replaceable module. The type of power supply
used by the unit (AC, DC, or Vdc/100) is dependent on the model number.

Attention:

Before starting any maintenance on the EU, read and observe

chapter 1.2

Health and Safety and the electrical installation information in chapter 4.2.1 Health
and Safety for electrical installation.

1. Danger: Electrical hazard. Danger of death or fatal injury from electrical

current inside the unit in operation. Before opening the unit, disconnect
mains power.

2. Caution: The unit reaches high temperature in operation. Risk of burns by

hot surface. Do not touch the unit before it has sufficiently cooled down.

Switch off the circuit breaker
supplying power to the EU.

Once you have confirmed that
the power has been shutdown,
remove Mains power
connector from the unit.

figure 5-1 Disconnect mains power

3. Locate the power supply on the

right side of the Extension Unit.
