2. Make sure that the operating environment and electrical installation meet the following standards.
- a. Indoor unconditioned/pollution degree 2.
- b. Overvoltage category 3.
3.
Review the wiring diagram. See step 1 in the Illustrations section.
All wiring must comply with local and national regulations regarding cross-section and ambient temperature require-
ments. Loose connections can cause equipment faults or reduced performance. Tighten the terminals according to the
proper torque value shown in step 8 in the Illustrations section.
4.
Review the fuse specifications. See step 2 in the Illustrations section.
The drive can be suitable for use on a ciruit capable of delivering up to 100 kA short circuit current rating (SCCR) at
480/600 V.
5.
Review the power cable specifications. See step 3 in the Illustrations section.
Use copper wire with a minimum 70 °C (158 °F).
6.
Install the drive following the numbered steps in the Illustrations section. Certain illustrations/steps pertain to specific frame
designations and are marked as such.
- a. Attach accessory bag components to the drive. (step 4)
- b. Mount the drive on or against a solid, non-combustible mounting surface such as a concrete or metal. Ensure

WIRING GUIDELINES
All wiring must comply with local and national regulations regarding cross-section and ambient temperature requirements. For
power connections, use copper wire with a minimum 70 °C (158 °F) rating. For aluminum wires, see the design guide.
-
Minimize interference by keeping control wires as short as possible and separate from high-power cables.
-
Loose connections can cause equipment faults or reduced performance. Tighten the terminals according to the proper tor-
que value shown in the illustrations.
• For control wire specifications, see step 7 in the Illustrations section.
•
For power cable specifications rated for 45 °C (113 °F) ambient temperature at 400 V, see step 3 in the Illustrations section.
•
For fuse ratings, see step 2 in the Illustrations section.
The drive is suitable for use on a circuit capable of delivering not more than 100 kA short circuit current rating (SCCR) at 480/600 V.
For circuit breaker and switch SCCR ratings, refer to the Operating Guide.
