1.
Read Section 1 'Safety information', before attempting to wire the supply to the actuator.
2.
Slow blow fuses should be fitted in all phases, but not in the protective earth conductor.
3.
The protective earth internal must be connected to the installation protective earth system. The integrity
of the installation protective earth system must not be compromised by the disconnection or removal
of other equipment.
4.
For supply connections, use 1.5 mm² wire, double insulated as stated in IEC 60364 (or equivalent), if
wires are exposed to touch.
5.
Increase the wire section according to the length of the power line.
6.
Dimension the safety transformer in the supply line correctly.
7.
Inrush currents shall not conduct to a too big voltage drop.
