Danger
Incorrect wiring can lead to serious injury from
electrical current and result in appliance dam-
age.
Take the following measures to prevent drifting
of wires into the adjacent voltage area:
■
Route LV leads < 42 V separately from cables
>
42 V/230 V~/400 V~ and secure with cable
ties.
■
Only strip the minimum of insulation from
cables as close as possible to the terminals
and bundle tightly to the corresponding termi-
nals.
■
If 2 components are connected to the same
terminal, press both cores together in a
single
wire ferrule.
