(2) CR751 controller
Fig. 2-11 : Connecting the power cable and grounding cable (CR751)
1) Please prepare the following: Leakage current breaker (with the terminal cover), cable for connecting the
primary power supply (AWG #14 (2mm
2
or above), cables to ground the primary power supply (AWG #12
(3.5mm
2
or above).
The secondary power cable (with the ACIN connector) for single phase or three phase power is supplied
with the product to match the specifications. When you build a cable suitable for your environment using
the ACIN connector and the ACIN terminal supplied, prepare a secondary power cable (AWG #14 (2mm
2
) or
above).
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 secondary power cable.
a) When using the supplied power cable with the ACIN connector
and connect the cable from the secondary side of the earth leakage breaker.
b) When building a power cable using the ACIN connector and the ACIN terminals supplied
Connect the ACIN terminals with the secondary power cable (prepared by customers), and insert the
ACIN terminals to the ACIN connector pins with the following numbers. Crimping caulking is
recommended to connect the ACIN terminals.
For single phase: 1 and 3
For three phase: 1, 2, and 3
Connect the cable from the secondary side of the earth leakage breaker.
5) Connect this ACIN connector to the ACIN connector on the front of the controller.
6) Connect the grounding cable to the PE terminal. (M4 screw)
7) Connect the primary power cable to the primary side terminal of the earth leakage breaker.
This completes the connection of the power and grounding cables.

Note 2)
Note 1) Crimping swage is recommended for connecting the attachment ACIN connector (soldering is also possible)
Recommendation compression tools: 234171-1(Tyco Electronics)
Note 2) The earth leakage breaker is the customer preparation. Always use the cover below.
Recommendation: For single primary power supply ...... NV30FAU-2P-10A-AC100-240V-30mA, (Cover: TCS-05FA2)
For three primary power supply ....... NV30FAU-3P-10A-AC100-240V-30mA, (Cover: TCS-05FA3)
Note 3) If necessary, as shown in the figure, connects the noise filter between ACIN terminal blocks and primary power supply.
(Recommended noise filter: SUP-EL20-ER6 *OKAYA ELECTRIC INDUSTRIES)
