2.3 Connection
2.3.1 Connecting the power cable and the grounding cable
The following shows how to connect the power cables and grounding cables.
Please install the earth leakage breaker in the primary side power supply of the
controller because of leakage protection.
1)
Prepare the following items.
2) Confirm that the primary power matches the specifications.
3) Confirm that the primary power is OFF and that the earth leakage breaker power switch is OFF.
4) 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.
5) Connect the ACIN cable to the ACIN connector on the rear of the controller.
<1> Face the main key on the ACIN cable plug upwards. (Refer to the "ACIN cable connection" illustration.)
<2> Align the main key of the ACIN cable plug with the grooves on the ACIN connector. Push the plug into the connec
-
tor as far as it will go.
The plug may be damaged if it is not correctly aligned with the connector.
<3> Tighten the coupling on the ACIN cable, turning it to the right until it locks.
6) Connect one end of the grounding cable to the PE (protective earth) terminal on the controller and ground the other end
(2-point grounding) in order to comply with the requirements of EN 61800-5-1 for the touch current of 3.5 mA AC or
more.
7) Connect the primary power cable to the primary side terminal of the earth leakage breaker.
