Electrical Connection
Low-voltage cables such as temperature sensor cables must be routed separately from mains voltage cables.
Before working on the unit, switch off the power supply and secure it against being switched on again! Check that there
is no power flowing! Electrical connections may only be made by a specialist and in compliance with the applicable
regulations. The unit may not be put into operation if there is visible damage to the housing, e.g. cracks.
The customer must provide an all-pole disconnecting device, e.g. an emergency heating switch.
The strain reliefs are suitable for flexible
cables with a cable sheath diameter of 5 mm
to 8 mm, primarily using the lower strain relief
(as shown). The cables must be checked for
firm placement. Solid, thicker and thinner
cables must always be laid firmly and must
be fixed on the installation side.
Solid cables or wires with special wire end
ferrules can simply be pushed into the ter-
minals. For other wires, the push button must
first be
completely pressed on
with a screw-
driver as shown.
Wire ferrules made of brass can be
difficult to clamp due to their asym-
metric crimping shape. In this case,
remove the wire ferrule. The plug-in
terminals are also suitable for flex-
ible cables.
