(a) Equipment complying with EN/IEC61000-3-12 (European/
International Technical Standard setting the limits for
harmonic currents produced by equipment connected to
public low-voltage systems with input current >16A and
≤75A per phase.).
(b) This equipment complies with EN/IEC61000‑3‑11
(European/International Technical Standard setting the
limits for voltage changes, voltage fluctuations and flicker in
public low-voltage supply systems for equipment with rated
current ≤75A) provided that the system impedance Z
sys
is
less than or equal to Z
max
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 system impedance Z
sys
less than or equal to
Z
max
.
Connect the backup heater power supply as follows:
a Factory-mounted cable connected to the backup heater
contactor inside the switch box (K5M for *6V and *9W
models)
b Field wiring (see table below)
