￭ North America
Installations must meet the requirements of UL (UL 508C) and/or CSA (C22.2 No. 14)
and be compliant with NFPA 70 (NEC)
1)
and/or Canadian Electrical Code (CE) along
with state and local codes for your location and application.
1)
National Fire Protection Association 70 (National Electric Code).
￭ Other regions
The disconnecting device must conform to the applicable local safety regulations.
Selecting the main contactor
You can equip the drive with a main contactor.
Obey these guidelines when you select a customer-defined main contactor:
• Dimension the contactor according to the nominal voltage and current of the drive.
Also consider the environmental conditions such as surrounding air temperature.
• Select contactor with utilization category AC-1 (number of operations under load)
according to IEC 60947-4, Low-voltage switch gear and control gear.
• Consider the application life time requirements.
Checking the compatibility of the motor and drive
Use asynchronous AC induction motor, permanent magnet synchronous motor or ABB
synchronous reluctance motor (SynRM motors) with the drive. Multiple induction motors
can be connected to the drive at a time when using the scalar motor control mode.
Make sure that the motor(s) and the drive are compatible according to the rating table
in the technical data.
Selecting the power cables
￭ General guidelines
Select the input power and motor cables according to local regulations.
• Current: Select a cable capable of carrying the maximum load current.
• Temperature: For an IEC installation, select a cable rated for at least 70 °C (158 °F)
maximum permissible temperature of conductor in continuous use. For North
America, select a cable rated for at least 75 °C (167 °F).
• Voltage: 600 V AC cable is accepted for up to 500 V AC. 750 V AC cable is accepted
for up to 600 V AC. 1000 V AC cable is accepted for up to 690 V AC.
To comply with the EMC requirements of the CE mark, use one of the preferred cable
types. See Preferred power cable types (page 48).
