Installation instructions
The sealing rings of the cable glands harden at low
temperatures.
Before installation, bring the sealing rings to a temperature
of at least 20 °C for 24 hours.
Before inserting the sealing rings and fixing them onto the
cable gland, knead the rings to ensure they are soft and
flexible.
IP rating IP66 / 67 is only achieved by installing the black
neoprene sealing ring between the cable gland and the
housing and by observing the tightening torque of 3.6 Nm
(Fig. 2, item
2
).
Cables must be protected against extreme mechanical loads
(caused by tension, torsion, crushing, etc.). Even under
operating conditions, it must be ensured that the cable
entry remains hermetically sealed. The customer must
provide a strain relief device for the cable.

1. Check that cable used is suitable (i.e., check the
mechanical resilience, temperature range, creep
resistance, resistance to chemicals, outside diameter,
etc.).
2. Strip the cable in accordance with Fig. 1.
3. Check the outer sleeve for damage and soiling.
4. Insert the cable in the cable gland.

5. Tighten the cable gland until the cable is firmly enclosed
by the sealing ring (Fig. 2, item
1
). Do not tighten more
than 1.5--times of the specified torque on the housing
(see assembly instructions for cable gland)!
Maintenance
Check the cable glands during each maintenance session. If
the cable is slack, retighten the cap(s) of the cable glands.
If it is not possible to retighten them, the cable gland will
need to be replaced.
M20 x 1.5 plastic cable gland for various types of
protection
The M20 x 1.5 plastic cable gland (supplied on an optional
basis) has a limited temperature range. The permissible
ambient temperature range of the cable gland is -20 … 80 °C
(-4 ... 176 °F). When using the cable gland, make sure that the
ambient temperature is within this range.
The cable gland must be installed in the housing with a
tightening torque of 3.8 Nm. On the cable side, when
installing the connection of the cable gland and cable, check
for integrity to ensure that the required IP rating is met.
