 High voltage must be strictly segregated from the AC 24 V safety extra low-voltage (SELV) when
wiring the system to protect against electric shock.
 When multiple controllers are connected to one power source, wrong wiring of AC / DC 24 V and
G0 will lead to damage or destruction of the controller and power supply.
 When DO is connected with an external intermediate relay, RWG universal controller’s M port
must be connected with the negative port of primary power supply, otherwise the controller will be
powered down in case of over current.
 The digital output must be connected with relays with double insulation to protect against electric
shock.
 Interconnecting devices with different reference potentials may generate unnecessary current,
which will lead to communication error or device damage.
 Please ensure that all the communication devices have the same reference potential , or add in-
sulation devices to avoid unnecessary current.
 Insulation devices need to be added for network stability and protection of communication inter-
face.
 Note: RWG1.M12 and RWG1.M8 don’t have the LCD display and buttons.
