(3) How to use the control circuit terminal block (Phoenix Contact make)
1) Termination of the cables
Solid wire: After the sheath has been stripped, the cable can be
used as it is. (Cable size: 0.2 to 2.5mm
Twisted wire: Use the cable after stripping the sheath and twisting the core. At this time, take care
to avoid a short caused by the loose wires of the core and the adjacent pole. Do not
solder the core as it may cause a contact fault. (Cable size: 0.2 to 2.5mm
Alternatively, a bar terminal may be used to put the wires together.(Phoenix Contact
make)

Main circuit power input terminals
Supply L1, L2 and L3 with the following power:
For single-phase 230VAC, connect the power supply L1/L2 and
leave L3 open.

230VAC, 50/60Hz
Note: Cannot be used for combination with the servo motor
HC-SF52.
Control circuit power input terminals
Supply L11 and L21 with single-phase 200-230VAC, 50/60Hz
power.
L11 and L21 should be in phase with L1 and L2, respectively.
Regenerative brake option connection terminals
C and D are factory-connected.
When using the regenerative brake option, always remove
wiring from across P-D and connect the regenerative brake
option across P-C.
Servo motor power output terminals
Connect to the servo motor power supply terminals (U, V, W).
Do not connect.
Ground terminal
Connect this terminal to the protective earth (PE) terminals of
the servo motor and control box for grounding.
