NOTICE
The measuring device does not have an internal circuit breaker.
‣
For this reason, assign the measuring device a switch or power-circuit breaker so that
the power supply line can be easily disconnected from the mains.
‣
Although the measuring device is equipped with a fuse, additional overcurrent
protection (maximum 10 A) should be integrated into the system installation.
6.1
Electrical safety
In accordance with applicable federal/national regulations.
6.2
Connection conditions
6.2.1
Required tools
• For cable entries: Use corresponding tools
• For securing clamp: Allen key 3 mm
• Wire stripper
• When using stranded cables: Crimper for wire end ferrule
• For removing cables from terminal: Flat blade screwdriver ≤ 3 mm (0.12 in)
6.2.2
Requirements for connecting cable
The connecting cables provided by the customer must fulfill the following requirements.
Protective grounding cable for the outer ground terminal
Conductor cross-section ≤2.08 mm
