Electrical connection

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 16 A) should be integrated into the system installation.
