The device power supply must not simultaneously supply machines or
equipment that cause grid interference (motors, relays, heaters, etc.). Even
brief surges or drops in the voltage supply can adversely affect how the device
functions or lead to damage. An uninterruptible power supply (UPS) or voltage
stabilizer can prevent this.
The device must be incorporated into the potential equalization of the system.
There is a threaded bolt on back for this purpose.
4.4 General cable assembly
All connection cables are directed through the bolted cable connection on the
bottom of the device to the inside of the housing.

► Slide the swivel nut over the cable sheath.
► Push the plastic insert over the cable sheath until the right edge of the
insert meets the end of the cable sheath.
► Unbraid the shield and lay it as flat as possible over the right part of the
plastic insert so that the shield is conductively connected with the housing.
The shield wires must not be longer than the right part of the insert.
Otherwise the bolted cable connection no longer provides a reliable seal.
