Mounting of Multi 9 format relays RH10M-21M-99M The relay can be mounted in three ways: b on a DIN rail b on a mounting plate using 3 M4 screws (not supplied) and 3 removable mounting accessories (supplied) b on a slotted mounting plate with M4 clip-on nuts (part no : 20 nuts). Mounting of front-panel mount relays RH10P-21P-99P, RHUs, RHU and RMH No special tools are required to mount the relay. Simply insert the device through the cutout. The size of the cutout complies with standard DIN Front panel thickness: 1 mm minimum / 2.5 mm maximum. The relay clips onto the panel. Mounting of RM12T multiplexer The multiplexer must always be mounted on a DIN rail. E90289 E92033 Front-panel mount. RHUs, RHU and RMH detail. Front-panel mount. RH10P, RH21P and RH99P detail.

Cable type Standard twisted pair (not to be run alongside power cables). E94433 In highly disturbed environments: Wiring Shielded twisted pair (not to be run alongside power cables). The shielding must be earthed at both ends by to the equipotential bonding circuit. The cable between the toroid and the relay should be as short as possible. If this is not sufficient, use a transformer with high frequency (HF) shielding. E94434 Auxiliary power supply via external transformer. 433E3100.fm/58
