Endress+Hauser Hart Proline Promag P 500 - Electrical Connection; Connection Conditions; Requirements for Connecting Cable

Electrical connection Proline Promag P 500 HART
38 Endress+Hauser
7 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 10 A) should be integrated into the system installation.
7.1 Connection conditions
7.1.1 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)
