Installation
1.The GL - CO - RFG65x should only be installed by a competent, suitably trained technician, experienced in installation with hazardous voltages.
(>50Vac & <1000Vac or >75Vdc & 1500Vdc)
2. Ensure that all power is disconnected before carrying out any work on the GL - CO - RFG365x. Maximum cable is 2.5mm², care must be
taken not to over tighten terminals.
3.Separate the base from the cover, if DIN rail mounting clip onto the DIN rail.
4. Make connections as required using the following cables:
— 1.5 mm² cross - section for power and relay control outputs,
— 1 mm² cross - section for sensors positioned up to a maximum distance of 50 meters; or
— 1.5 mm² cross - section for sensors positioned up to a maximum distance of 75 meters.
5.NB It is advised that no more than 2 cables be inserted into a single terminal. Use external junction boxes if necessary.
6. Select the “ link functions ” to adapt the detector to the desired type of operational control the replace the cover on the base using the 4
