Delta ASDA-A3 Series User Manual page 5

Main Circuit Wiring
 Do not put the power cable and signal cable in the same channel or bond them together.
Separate the power cable and signal cable by at least 30 centimeters (11.8 inches).
 Please use stranded wires and multi-core shielded-pair wires for signal cables and encoder
feedback cables. The maximum length of signal input cable is 3 meters (9.84 feet) and the
maximum length of feedback cable is 20 meters (65.62 feet).
 The high voltage may remain in the servo drive immediately after the power is turned off.
Please wait for 10 minutes before touching the terminals.
Do not repeatedly turn the power on and off. If it is necessary to turn the power on and off,
make sure that you wait one minute at least before turning the power on or off again.
Terminal Wiring of the Main Circuit
 When wiring the servo drive, please remove the terminal blocks from the servo drive.
 Insert only one electric wire per terminal socket.
 When inserting the electric wires, do not short circuit the adjacent conductors.

Leakage Current
 The leakage current of the servo drive is greater than 3.5 mA.
 According to the IEC 61800-5-1 standards, the wires must comply with one of the
following specifications to ensure proper grounding:
1. Copper wire cross-sectional area is at least 10 mm
2. Aluminum wire cross-sectional area is at least 16 mm
 Failure to comply with the specifications may result in personnel injury.
Before applying power, please inspect and ensure that the wiring is correct.
