5 Electrical Installation
5.1 Safety Instructions
See 2.3 Safety Precautions for general safety warnings.
NOTICE
APPLICATIONS WITH MULTIPLE MOTORS
To provide overcurrent protection, extra protective equipment such as short-circuit protection or motor thermal protection
between drive and motor is required for applications with multiple motors.
NOTICE
WIRE TYPE AND RATINGS
All wiring must comply with local and national regulations regarding cross-section and ambient temperature requirements. For
power connections, minimum 75 °C (167 °F) rated copper wire is recommended.
WARNING
INDUCED VOLTAGE
Induced voltage from output motor cables that run together can charge equipment capacitors, even with the equipment
turned off and locked out. Failure to run output motor cables separately or to use shielded cables could result in death or
serious injury.
-
Run output motor cables separately.
-
Use shielded cables.
WARNING
SHOCK HAZARD
The drive can cause a DC current in the PE conductor. Failure to use a Type B residual current-operated protective device (RCD)
may lead to the RCD not providing the intended protection and therefore may result in death or serious injury.
-
When an RCD is used for protection against electrical shock, only a Type B device is allowed on the supply side.
CAUTION
MOTOR OVERLOAD
Protection against motor overload is not included in the default setting. For the North American market, the ETR function
provides class 20 motor overload protection in accordance with NEC. Failure to set the ETR function means that motor overload
protection is not provided and property damage can occur if the motor overheats.
-
Enable the ETR function by setting parameter 1-90 Motor Thermal Protection to [ETR trip] or [ETR warning].
5.2 EMC-compliant Installation
To obtain an EMC-compliant installation, be sure to follow all electrical installation instructions.
