Routing cables to the connection area
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
Incorrectly routed wiring can lead
to serious injury from electrical
current and result in equipment
damage.
■ Route LV leads < 42 V and
cables > 42 V/230 V~/400 V~
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.
This ensures that, should there
be an error, for example when
detaching a wire, the wires can-
not drift into the adjacent voltage
area.
Installation sequence
When routing the on-site power cables,
observe the location of the cable entries
into the appliance via its back panel (see
page 10).
