FR series 4 - 9
4.2 Mains connection and grounding
Refer to Section 3.6 on how to ground the robot arm.
4.2.1 CR800 controller
Make sure that the mains voltage and the power switch of the controller are switched off.
Prepare the mains line (feed) and the grounding cable. Use cable with a minimum cross-section
of 2 mm².
Connect the ACIN cable to the breaker. Connect the power terminals of the ACIN cable to the
secondary side terminals of the earth leakage breaker. Also, ground the FG terminal of the cable.
Connect the ACIN cable to the ACIN connector on the rear of the controller.
Connect one end of the grounding cable to the PE (protective earth) terminal on the controller
and ground the other end.
Connect the primary power cable to the primary side terminal of the earth leakage breaker.
Recommended earth leakage breaker:
Single phase: NV30FAU-2P-10A-AC100-240V-30mA, (Terminal cover: TCS-05FA2)
Three phase: NV30FAU-3P-10A-AC100-240V-30mA, (Terminal cover: TCS-05FA3)

CAUTION:
●
Only carry out connection work at the controller when the main switch for the power supply
is switched off and protected against being switched back on.
●
Please install the earth leakage breaker in the primary side power supply of the controller
because of leakage protection.
