Cautions for wiring
1. The input are all the no voltage contact
2. Use a contact which can guarantee minimum application load DC16V and 10mA
3. Do not use multicore cables with three or more cores
4. Use wires of sizes between 0.75mm
2
and 1.25mm

5. Do not bind the wire for control
6. Wirings for control must be isolated from the power lines
7. Terminals G are inter-connected. Connecting to either one is allowed, but the number of cables connectable
to one terminal is limited to 2 pieces
8. Wire length : Max 150m
Recommended wire size 0.75~1.25mm
