* Only for versions with outside diameters 22 mm and 42 mm.
• Comply with the installation and safety instructions in the Operating Instructions.
• Install the device according to the manufacturer's instructions and any other valid standards and regulations.
• Do not operate the device outside the specified electrical, thermal and mechanical parameters.
• Connect cable screen to earth ground of the installation.
• The circuit of the device is isolated from ground potential and has a dielectric strength of at least 500 V
with respect to it.
When shortening the length of the cable ensure that this dielectric strength is maintained for connection
wires and earth grounded screen.
• Avoid impact and friction sparks (anchor equipment if necessary/secure against swinging).
• Do not disconnect electrical connections under voltage in an explosive atmosphere.
