Important safety information

•
The device must always be protected against wetness and mois-
ture. Under no circumstances may it be exposed to splashed water
or condensate.
•
Surge category II

Soiling degree II
Requirements of cable for operating voltage and
system components and installed lines
Use only cables and installed lines which meet the following require-
ments:
•
The terminal strips on the circuit board require core cross-sections
of between 0.08 and 2.5 mm
2
. This applies to single-wire and fine-
wire cores with wire end ferrules without plastic collar.
For fine-wire cores with wire end ferrules and plastic collar, the
cross-section may be up to 1.5 mm
2
.
For single-wire cores, AWG28
– AWG12 can also be used.
•
The cable ducts installed by the manufacturer in the device have a
clamping range of 4.5 to 10 mm. This means that the external di-
ameter of the laid cable must remain within the range of 4.5 to 10
mm. If you use other ducts, the cable diameters must correspond
to the ducts.
Optimum cross-section of the cores
If the core cross-section is less than 0.5 mm
2
, jamming may occur
when the cores are loosened from the terminal strip. We therefore
recommend using wires with cross-sections greater than 0.5 mm
2
.
Requirements for cable ducts
•
The recesses in the housing are intended for M16 ducts.
•
The ducts should have a smooth and rounded opening (to protect
against bending and abrasion).
•
The duct should include a strain relief that prevents slippage of the
cable and that cannot be disengaged without a tool.
•
You can order cable ducts from us as spare parts (see
Modul CL spare parts and accessories
on page 48).
During assembly
•
Always disconnect the relevant system component from the power
source before assembling the device or connecting it to the power
supply or disconnecting it from the same. Prevent any inadvertent
reactivation of the device.
•
Only connect the device to the operating voltage as specified on
the type plate.
•
Observe the technical data and the environmental parameters.
