Installation and

Installation and connection 2 Connection diagram Special precautions b Never connect or disconnect a connector while the device is energised. b Check voltages before connecting. b Always energise the RM12T multiplexer before the Vigirex RMH. Protection of the device b The Vigirex RMH is supplied by 220/240 V AC 50/60 Hz power. b Recommended protection for wiring of the Vigirex RMH: v C60N phase + neutral or 2-pole circuit breaker or DPN phase + neutral circuit breaker (1 A, curve C or D) v STI isolatable fuse carrier (with 1 A fuse). Types of toroids to be used Two types of toroids may be connected: types A and OA. The toroid characteristics are indicated in the Vigirex catalogue. Compatibility with E toroids in existing installations: b TE (Ø 30 mm) ; PE (Ø 50 mm) : total compatibility b IE (Ø 80 mm) ; ME (Ø 120 mm) ; SE (Ø 200 mm) ATTENTION The thresholds should never be set to less than 300mA for these threetoroids, IE, ME and SE. b Maximum cable lengths between toroid and RM12T multiplexer 10 m. Connecting the toroids: The toroids (12 maximum) are connected to the RMH via a RM12T selector. Requirements concerning the cable connecting the RMH to the RM12T: b maximum length of 10 metres. four wires (two twisted pairs). b The Vigirex RMH automatically recognises any new toroid added when it is energised.
