Chapter 2 Installation and Wiring
2.1 Installation Environment
1） Ambient temperature is in the range of -10℃~ 40℃.
2） Drive should be installed on surface of flame retardant object, with adequate surrounding
space for heat dissipation.
3） Installation should be performed where vibration is less than 5.9m/s2 (0.6g).
4） Protect from moisture and direct sunlight.
5） Protect the cooling fan by avoiding oil, dust and metal particles.
6） Do not expose to an atmosphere with flammable gases, corrosive gases, explosive gases
or other harmful gases.
7） Prevent drilling residues, wire ends and screws falling into drive.
8） Ventilation part of the drive should be installed outside, away from harsh environment (e.g.
textile facilities with fiber particles and chemical facilities filled with corrosive gases).
2.2 Main Circuit Terminals and Wiring
WARNING
 Wiring should be in strict accordance with this manual, otherwise hazard of electric
shock or equipment damage exists.
 Since leakage current of the drive may exceed 3.5mA, for safety's sake, the drive and
the motor must be grounded so as to avoid hazard of electric shock.
 Be sure to perform wiring in strict accordance with the drive terminal marks. Never
connect three-phase power supply to output terminals U, V and W. Failure to comply
will result in equipment damage.
 Only mount braking resistors at terminals and BR when need. Failure to comply will
result in equipment damage.
 Signal wires should be far away from main power lines to the best of possibility. If this
cannot be ensured, vertical cross-arrangement shall be implemented, otherwise
interference noise to control signal may occur.
 If motor cables are longer than 50m, it is recommended output AC reactor be used.
Failure to comply may result in faults.

2.3 Control Terminal Wiring
WARNING
 AC 220V signal is prohibited from connecting to other terminals than control terminals
RA, RB and RC. Failure to comply may result in equipment damage.
 Shielded cables are highly recommended and the cables should be as short as possible
in order to avoid any faults caused by interference.
