Danger
Damaged cable insulation can
cause injury and damage to the
appliance.
Route cables so that they cannot
touch very hot, vibrating or sharp-
edged components.
Danger
Incorrect wiring can lead to seri-
ous injury from electrical current
and result in appliance damage.
■ Route LV leads < 42 V and
> 42 V/230 V~/400 V~ cables
separately.
■ Strip the insulation from the
cables as close to the terminals
as possible, and bundle tightly
to the corresponding terminals.
■ Secure cables with cable ties/
strain relief fittings.
This ensures that, should there
be a fault, for example when
detaching a wire, the wires can-
not drift into the adjacent voltage
area.
When routing the on-site power cables,
observe the location of the cable entries
into the appliance through its back panel
(see page 21).
