Power Supply
The unit can be powered from DC or AC power within the limits specified in
Chapter 1.
There are two power
supplies allowing redundancy to ensure operation even if one of the power supplies is interrupted.
All power connections should use insulated flameproof flexible cable (BWF type) with a 1.5 mm² cross
section, 70 °C thermal class, and 750V insulation voltage.
To reduce the risk of electrical shock, pre-insulated tubular pin terminals should be used on the ends of the
power connections.
Figure 6: Pre-insulated tubular pin terminals
The pin terminals should be completely inserted into the connector supplied with the unity so that no metallic
parts are exposed, according to the
Figure 7: Supply connector assembly
A 1.5 mm² ground lead shall be connected to the terminal marked with the protective earth symbol for safety.
