10 ELECTRIC WIRING
10.1 GENERAL CHECK
1 Ensure that the eld-supplied electrical components (mains
power switches, circuit breakers, wires, connectors and wire
terminals) have been properly selected according to the
electrical data indicated. Make sure that they comply with
national and regional electrical codes.
2 Following the Council Directive 2004/108/EC (89/336/EEC),
relating to electromagnetic compatibility, next table indicates:
Maximum permissible system impedance Z

4 Check to ensure that the power supply voltage is within
+/- 10% of the rated voltage.
5 Check to ensure that power supply has an impedance low
enough to warranty not reduce the starting voltage more
than 85% of the rated voltage.
6 Check to ensure that the ground wire is connected.
7 Connect a fuse of specied capacity.
