intrinsically safe (EEx-). The isolation amplifier and speed monitor must not be located in the potentially explosive area. If an isolation amplifier is used for the potentially explosive environment, only the wire-breakage identification must be active for the power supply lines. Wire breakage and short circuit on the output conductor of the pick-up are not signalled via the fault signal relay but via the output relay through too low speed. 6.1 Isolation amplifier6.1.1 Connection values Potentially explosive area NAMUR Bi5-G1-Y1MK1--Ex0/2VDC EWD/2...2VUC The EWD complete system must not be used in potentially explosive environments as defined in Directive 9/9/EC!Caution!
