Issue Number: 4
13 UL Information
13.1 UL file reference
Unidrive M Frame size 3, 4, 5, 6, 7, 8, 9, 10 and 11 are UL Listed to both Canadian and US requirements'. The UL file reference is: NMMS/7.E171230.
Products that incorporate the Safe Torque Off (STO) function are Certified for Functional Safety. The UL file reference is: FSPC.E171230.
13.2 Option modules, kits and accessories
Option Modules, Control Pods, Installation Kits and other accessories for use with these drives are UL Listed.
13.3 Enclosure ratings
With the exception of free-standing cubicle drives, all models are Open Type as supplied.
The drive enclosure is not classified as a fire enclosure. A separate fire enclosure must be provided. A UL/ NEMA Type 12 enclosure is suitable.
When fitted with a conduit box the drives meet the requirements for UL Type 1. Type 1 enclosures are intended for indoor use, primarily to provide a
degree of protection against limited amounts of falling dirt.
The drives meet the requirements for UL Type 12 when installed inside a Type 12 enclosure and through-hole mounted using the sealing kit and the
high-IP insert (where provided).
When through-hole mounted, the drives have been evaluated as suitable for use in surrounding air temperatures up to 40 °C.
Remote Keypads are UL Type 12 when installed with the sealing washer and fixing kit provided.
When installed in a Type 1 or Type 12 enclosure, the drives may be operated in a compartment handling conditioned air.
13.4 Mounting
Drives may be surface, through-panel or tile mounted using the appropriate brackets. Drives may be mounted singly or side by side with suitable
space between them (bookcase mounting).
13.5 Environment
Drives must be installed in a Pollution Degree 2 environment or better (dry, non-conductive pollution only).
The drives have been evaluated for use at ambient temperatures up to 40 °C. The drives have additionally been evaluated for 50 °C and 55 °C
ambient air temperatures with a derated output.
13.6 Electrical Installation
OVERVOLTAGE CATEGORY
OVC III
SUPPLY
The drives are suitable for use on a circuit capable of delivering not more than 100,000 RMS symmetrical amperes, 600 Vac Maximum.
TERMINAL TORQUE
Terminals must be tightened to the rated torque as specified in the Installation Instructions.
WIRING TERMINALS
Drives must be installed using cables rated for 75 °C operation, copper wire only.
Where possible, UL Listed closed-loop connectors sized according to the field wiring shall be used for all field power wiring connections.
GROUND CONNECTION INSTRUCTIONS
UL Listed closed-loop connectors sized according to the field wiring shall be used for grounding connections.
BRANCH CIRCUIT PROTECTION
The fuses and circuit breakers required for branch circuit protection are specified in the Installation Instructions.
OPENING OF BRANCH CIRCUIT
Opening of the branch-circuit protective device may be an indication that a fault has been interrupted. To reduce the risk of fire or electric shock, the
equipment should be examined and replaced if damaged. If burnout of the current element of an overload relay occurs, the complete overload relay
must be replaced.
Integral solid state short circuit protection does not provide branch circuit protection. Branch circuit protection must be provided in accordance with
the National Electrical Code (NEC), The Canadian Electrical Code, and any additional local codes.
DYNAMIC BRAKING
M100, M101, M200, M201, M300 or M400, frame sizes 1 to 4 have been evaluated for dynamic braking applications. Other drive models have not
been evaluated for dynamic braking.
