CONDITIONS OF ACCEPTABILITY:
Use - For use only in complete equipment where the acceptability of the combination is determined by
Underwriters Laboratories Inc.
1. These drives are incomplete in construction and have to be attached to an external heatsink in the
end-use. Unless operated with the heatsink as noted in item 2 of the conditions of acceptability
below, temperature test shall be conducted in the end-use.
2. Temperature test was conducted with drive installed on aluminum heatsink, overall dimensions
and ribs shape as outlined below:
3. Suitability of grounding for the combination of drive and heatsink needs to be verified in accordance
with the end-use standard.
4. Temperature test was not conducted on models INV MD 4. Suitability of drive - heatsink combina-
tion shall be determined by subjecting to temperature test in the end-use.
Required Markings
Internal Overload Protection Operates within 60 seconds when reaching 150 % of the Motor Full Load Current.
Suitable for use on a circuit capable of delivering not more than 5 kA rms symmetrical amperes, 230 Volts
for INV Mx 2 or 480 Volts for INV Mx 4, maximum when protected by fuses.
"Warning" – Use fuses rated 600 V/30 A for INV MB 4 only.
"Warning" – Use fuses rated 600 V/30 A for INV MC 4 only.
"Warning" – Use fuses rated 600 V/70 A for INV MD 4 only.
Integral solid state short circuit protection does not provide branch circuit protection. Branch circuit protec-
tion must be provided in accordance with the Manufacturer Instructions, National Electrical Code and any
additional local codes.
All wiring terminals marked to indicate proper connections for the power supply, load and control circuitry.
