Power Supply
The unit can be powered from a DC or AC power supply within the limits specified.
The power connections must use insulated flameproof flexible cable with a 1.5 mm²
cross section, 70 °C thermal class, and 750 V 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 5: Pre-insulated tubular pin terminals
The pin terminals must be completely inserted into the connector supplied with the
unity so that no metallic parts are exposed, according to the figure below.
