• IP 54 / UL type 12 enclosure, indoor use only. This enclosure provides protection from
airborne dust and light sprays or splashing water from all directions.
• UL Type 3R- Enclosures are intended for outdoor use to provide a degree of protection
from falling rain. Undamaged by the formation of ice on the enclosure. May be cooled by
forced air and louvers for vents.
• IP 56 / UL type 4 enclosure. Constructed for outdoor use or hose down applications.
Provides a degree of protection against falling dirt, rain, sleet, snow, windblown dust and
splashing water. Not suitable for direct sun. A sun shield or canopy may be required.
Suitable Mounting Location
Confirm that the mounting location meets the following constraints:
• The drive must be mounted vertically on a smooth, solid surface, and in a suitable
environment as defined above.
• The minimum space requirements for the drive are the outside dimensions (see “Outside
Dimensions” on page 141 and 143), plus air flow space around the unit (see “Cooling” on
page 137).
• The distance between the motor and the drive is limited by the maximum motor cable
length. See “Motor Connection” on page 136.
• The mounting site must support the drive’s modest weight and noise output. See
“Dimensions and Weights” on page 141.
Wiring and EMC Considerations
Determine electromagnetic compliance (EMC) requirements per local codes. In general,
always follow the NEC in the absence of a local code.
• Follow local codes for cable size, conduit, grounding and motors.
• Keep these four classes of wiring separated: input power wiring, motor wiring, control/
communications wiring. Always use separate conduit for motor/control wires.
• Refer to the specifications/recommendations in:
“Cable Sizing/Rating” on page 131, “Cable Terminals” on page 135, “Input Power (Mains)
Connection” on page 136 and “Motor Connection” on page 136.
• Multiple motor wire should always be run in separate conduit. Shielded and grounded!
Control Cables
General Recommendations
Use shielded cables, temperature rated at 60º C (140º F) or above:
• Control cables must be multi-core cables with a braided copper wire screen.
Double Shielded Single Shielded
Example: JAMAK by Draka NK Cables Example: NOMAK by Draka NK Cables
• The screen must be twisted together into a bundle not longer than five times its width and
connected to terminal X1-1 (for digital and analog I/O cables) or to either X1-28 or X1-32
(for RS485 cables).
