Safety Information
Note for UL approved system with integrated controllers
UL warnings are notes which apply to UL systems. The documentation contains special information
about UL.
• Integral solid state protection does not provide branch circuit protection. Branch
circuit protection must be provided in accordance with the National Electrical
Code and any additional local codes. The use of fuses or circuit breakers is the
only approved means for branch circuit protection.
• When protected by CC and T Class Fuses, suitable for use on a circuit capable
of delivering not more than 200,000 rms symmetrical amperes, at the maximum
voltage rating marked on the drive.
• Additionally suitable when protected by a circuit breaker having an interrupting
rating not less than 200,000 rms symmetrical amperes, at the maximum
voltage rating marked on the drive. (Excludes ESMD113_4T_, ESMD112_2Y_,
ESMD113_2T_, ESMD152_2Y_, ESMD153_2T_, ESMD222_2Y_, ESMD223_4T_,
ESMD402_2T_, ESMD552_2T_, ESMD752_2T_, ESMD153_4T_, and
ESMD183_4T_).
• Use minimum 75°C copper wire only, except for control circuits.
• For control circuits, use wiring suitable for NEC Class 1 circuits only.
• Torque Requirements are listed in section 3.2.3, Connection diagram.
• Shall be installed in a pollution degree 2 macro-environment.
Warnings!
DANGER!
Risk of Electric Shock! Capacitors retain charge for approximately 180
seconds after power is removed. Disconnect incoming power and wait at
least 3 minutes before touching the drive.
WARNING!
The opening of branch-circuit protective device may be an indication that a
fault has been interrupted. To reduce the risk of fire or electric shock, current
carrying parts and other components of the controller should be examined
and replaced if damaged.
