Additional notes on devices with integrated heating
When using heated devices, the following additional points must be noted:
■
Use cables suitable for the environmental conditions. In case of doubt, consult
SICK Service.
■
Connection work only in the temperature range: 0 °C ... +50 °C
■
Only operate in idle state (no mounting or connection work).

Note on the swivel connector
NOTE
The swivel connector is type-dependent. It is not available in all device models.
NOTICE
Damage to the connector unit from over-tightening!
The connector unit on the device has two opposite end positions.
■
Do not rotate the connector unit from either of the two end positions by more than
180°.
■
Always rotate the connector unit in the direction of the display LEDs.

Prerequisites for the safe operation of the device in a system
WARNING
Risk of injury and damage caused by electrical current!
As a result of equipotential bonding currents between the device and other grounded
devices in the system, faulty grounding of the device can give rise to the following dan‐
gers and faults:
■
Metal housings are vulnerable to dangerous currents.
■
Devices will behave incorrectly or be destroyed.
■
Cable shielding will be damaged by overheating and cause cable fires.
Remedial measures
b
Only skilled electricians should be permitted to carry out work on the electrical sys‐
tem.
b
Ensure that the ground potential is the same at all grounding points.
b
If the cable insulation is damaged, disconnect the voltage supply immediately and
have the damage repaired.
b
Where local conditions are unfavorable and thus do not meet conditions for a safe
earthing method (same ground potential at all grounding points), take measures
in accordance with the following formats.
