Connecting the electrical wiring

WARNING
Danger to life from electric shock!
The devices are operated with 230 V or 400 V alternating current. Improper installation can present
a danger to life from electric shock as well as a danger of fire occurring due to overheating.
► Electrical installation work must be undertaken by a trained electrician.
► Ensure that you have disconnected the electricity supply before you carry out installation
work. Secure the electricity supply against being switched on again unintentionally.
ATTENTION
Danger of damage due to unprofessional installation
► When making electrical wiring connections, respect the relevant requirements for cable
type, cable cross section and recommended fuse (→
systems), p.
required contact clearance and the maximum permissible cable length (if indicated) as
well as the connecting conditions for the individual devices (→
► Pay attention to the correct polarity while connecting the cabling. Connecting the cabling
with incorrect polarity can cause electrical shocks or fire.
► Guide the cable through cable grommets into the device, so that the cable will not be
damaged by sharp edges.
► Make sure that the cables do not come into contact with hot objects such as the water
pipes, so that the insulation is not damaged.

IMPORTANT
When connecting electrical wiring, also respect the following specifications.
Requirements for correctly configured cable connections
1. Note the following requirements for the insulation:
a. The insulation having a length of 10 mm ±1 mm must be stripped from the wire end. See that
no strand is loose and that all strands are clamped.
b. See that the stripped end of the wire is fully inserted into the terminal. Neither should the
insulation be inserted in the terminal, nor should the stripped end of the wire project out from
the terminal.
c. The gap between the cables must be a minimum of 5 mm.
