Danger
Damaged wiring insulation wiring can lead to
serious injury from electrical current and result in
appliance damage.
Route cables so that they cannot touch very hot,
vibrating or sharp-edged components.
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.
Danger
In terms of safety, the BUS cables for the inter-
nal/external units (12 V or 43 V) do
not count as
LV leads. In the event of certain errors, these
BUS cables may still carry a mains voltage.
Contact with the BUS cables can lead to serious
injury from electric current.
The BUS cables
must be routed together with
the 230 V cables.
Note
Make all connections on the control panel, (see
page 24) with
flexible cables to ensure that the con-
trol panel can be placed in the service position (see
page 61).
