Peripheral devices/cable size list
Check the model name of the drive unit you purchased. Appropriate peripheral devices must be selected according to the
capacity.
Refer to the following list and prepare appropriate peripheral devices.


Select an MCCB according to the drive unit power supply capacity.
Install one MCCB per drive unit.

For the use in the United States or Canada, select a UL and cUL certified fuse with Class T fuse equivalent
cut-off speed or faster with the appropriate rating for branch circuit protection. Alternatively, select a UL489
molded case circuit breaker (MCCB).

Magnetic contactor is selected based on the AC-1 class. The electrical durability of magnetic contactor is 500,000 times. When the magnetic contactor is used
for emergency stop during motor driving, the electrical durability is 25 times.
If using an MC for emergency stop during motor driving, select an MC regarding the drive unit input side current as JEM1038-AC-3 class rated current.

The power factor may be slightly lower.

The cable size is that of the cable (HIV cable (600V class 2 vinyl-insulated cable) etc.) with continuous maximum permissible temperature of 75°C. It assumes
that the surrounding air temperature is 50°C or less and the wiring distance is 20m or less.


The gauge is 0.75mm (AWG19 or AWG18) for the motor power supply cable for the MM-GKR series (MR-PWS1CBLM-A-).
Note
 When the breaker on the drive unit input side trips, check for the wiring fault (short circuit), damage to internal parts
of the drive unit, etc. Identify the cause of the trip, then remove the cause and power on the breaker.
REMARKS
 The following table indicates a selection example for the 600V grade heat-resistant PVC insulated cable (HIV cable) with the
reference wiring length of 30m.


Use a fluorinated resin cable (0.75mm

The gauge is for the wiring length of 10m. For the wiring length longer than 10m, use MR-PWS2CBL03M-A_-L and an HIV cable having the gauge of
2
1.25mm (AWG16) for extension.

For compliance with UL/CSA standard, use MR-PWS2CBL03M-A_-L and an HIV cable having the gauge of 2mm
