13.1 GENERAL CHECK

1
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
interface point of the user's supply, in accordance with
EN61000-3-11.

3 Harmonics situation of each model regarding IEC 61000-3-2
and IEC 61000-3-12 is as follows:
MODELS SITUATION REGARDING
IEC 61000-3-2 AND
IEC 61000-3-12 Ssc "xx"
Equipment complying with IEC
61000-3-12 (professional use)
This equipment complies with IEC
61000-3-12 provided that the short-
circuit power Ssc is greater than or
equal to xx (see Ssc column) at the
interface point between the user's
supply and the public system. It is
the responsibility of the installer or
user of the equipment to ensure,
by consultation with the distribution
network operator if necessary, that the
equipment is connected only to a supply
with a short-circuit power Ssc greater
than or equal to xx (see Ssc column)
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.
