Cable Routing

The structure of the terminals conforms to JCS standards stipulated by the Japanese Electric Wire & Cable Makers'
Association. Route the cables according to the JCS standards appropriate for the input voltage used.
Cable routing examples are shown below.
Note: Secure the cables with cable brackets. Do not secure them at an intermediate point between the cable bracket and control circuit
terminals. Prepare cable brackets suitable for the size of the cables used.
u Main Circuit Cable Routing
Main Circuit Input-Side Cable
n
Route the input cable into the transformer panel through the drive cable inlet port at the bottom of the transformer panel.
Mount a cable bracket on the cable bracket clamp near the cable inlet port to secure the cables.
Main Circuit Output-Side Cable
n
Route the output cable into the Power Cell panel through the drive cable outlet port at the bottom of the transformer
panel.
Mount a cable bracket on the cable bracket clamp near the cable inlet port to secure the cables.
NOTICE: Keep the wiring for the main circuit separate from that for the control circuit. Select a power supply with a capacity larger
than that of the drive to be connected. When connecting multiple drives to a single power supply, select a power supply with a capacity
larger than the sum of the power required by all the drives to be connected. Even when the power supply has sufficient capacity, the
power supply voltage may drop when the power is turned on, causing malfunction of connected devices if the power supply has a large
power impedance.
NOTICE: Equipment Hazard. Verify all control wiring and main circuit wiring is properly terminated and correctly connected to the
proper terminals before applying power. Failure to comply may result in damage to the drive circuitry.
