Wiring precautions
General To ensure the best performance, inputs I0 to I5 are rapid inputs. If the actuator is a dry contact, the inputs must be connected by a twisted pair, or by a shielded cable if the sensor is a two or threewire proximity detector. The module includes as standard basic protection against short circuits or voltage inversions. However, the module cannot remain operational for long with an error. You must therefore ensure that the fuses in series with the supply carry out their protective function. These are 1A maximum fast-blow fuses, the supply energy must be sufficient to ensure their fusion.

Important note: wiring of Q0 static outputs The actuator connected to the Q0 brake output has its shared pin connected to supply 0 V. If for any reason there is a 0 V outage of the output amplifier supply (e.g. poor contact or accidental unplugging), when the 0 V of the actuators remains connected to the 0 V supply, there may be enough mA output current from the amplifier to keep low-power actuators triggered. Illustration:
Connection via TELEFAST If the shared actuators are connected to the bar for shared points 200 to 215 (jumper wire in position 1-2), there can be no outage of the shared module without an outage of the shared actuators.
Connection using a TSX CDP 301 / 501 pre-wired strand This kind of connection must be carried out with the greatest care and attention. It is recommended that you take special care in wiring this cable, for example using the cable ferules on screw terminals. It may be necessary to double the connections in order to ensure permanent contacts. When the actuator supply is a long distance away from the modules and close to the shared actuators, there may be an accidental break of the link between the latter and the 0 V terminal of the module(s). Illustration:
If there is a break of the supply section between A and B, there is a risk that the RL actuators may not remain operational. You must, if possible, double connections of 0 V supply to the modules.
