Cable model code: CB-ERC3P-PWBIOƑƑƑ
ERC3 possesses a built-in controller in the actuator body. The frame ground line for this
controller is equipped in the PIO type power and I/O cable. Connect this to the ground terminal
using a relay terminal block.
For the grounding line after the relay terminal apply a low carbon steel wire with the diameter
1.6mm (AWG14: 2mm 2 ) or more.
