6.1.2 Note on the swivel connector
NOTICE
Damage to the connector from over-rotation!
The swivel connector has two opposite end positions.
■
Do not rotate the connector from either of the two end positions by more than
180° in the opposite direction. Do not exceed the respective limit position.
■
Carry out the rotational movement slowly.

6.1.3 Prerequisites for safe operation of the device
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:
■
Dangerous voltages are applied to the metal housings.
■
Devices will behave incorrectly or be destroyed.
■
Cable shielding will be damaged by overheating and cause cable fires.
Remedial measures
■
Only skilled electricians should be permitted to carry out work on the electrical sys‐
tem.
■
If the cable insulation is damaged, disconnect the voltage supply immediately and
have the damage repaired.
■
Ensure that the ground potential is the same at all grounding points.
■
Where local conditions do not meet the requirements for a safe earthing method,
take appropriate measures (e.g., ensuring low-impedance and current-carrying
equipotential bonding).
