3.
Strip the flexible line as shown in the figure. In doing so,
ensure that the insulation on the individual conductors
is not damaged.
4.
Only strip inner conductors just enough to establish
good, sound connections.
5.
To avoid short circuits resulting from loose individual
wires, fit conductor end sleeves on the stripped ends of
the conductors.
6.
Screw the respective plug to the connection cable.
7.
Check whether all conductors are properly fastened

Establishing the power supply
Caution.
Risk of material damage due to high con-
nected voltage.
At mains voltages greater than 253 V, elec-
tronic components may be damaged.
Make sure that the rated voltage of the
mains is 230 V.
Observe all valid regulations.
Open the electronics box. (→ Page 16)
Set up a fixed connection and install a partition with
a contact gap of at least 3 mm (e.g. fuses or power
switches).
Use a flexible line for the mains feed line, which is
routed through the grommet into the product.
Carry out the wiring. (→ Page 17)
Screw the supplied plug to a three-core power supply
cable that complies with the relevant standards.
Close the electronics box. (→ Page 16)
Make sure that access to the power supply is always
freely available and is not covered or blocked by an
obstruction.
Installing the product in protective area 1 or 2
Danger!
Risk of death from electric shock!
If you install the product in protective area 1
or 2 and you use the standard connection
cable with an earthed plug for this, there is a
risk of death from electric shock.
Connect the product using a fixed connec-
tion and a partition with a contact open-
ing of at least 3 mm (e.g. fuses or power
switches).
Use a flexible line for the mains feed line,
