Endress+Hauser Proline Prosonic Flow B 200 - Electrical Connection

Electrical connection Proline Prosonic Flow B 200 HART
24 Endress+Hauser
7 Electrical connection
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.
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: crimping tool for ferrule
• For removing cables from terminal: flat blade screwdriver ≤3 mm (0.12 in)
