Safety Information
Safety Information in accordance with UL:
Note for UL approved system with integrated controllers: UL warnings are notes which apply to UL systems.
The documentation contains special information about UL.
Warnings!
• 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
ESV113xx2T, ESV153xx2T, ESV113xx4T, ESV153xx4T, ESV183xx4T, ESV223xx4T, ESV303xx4T,
ESV113xx6T, ESV153xx6T, ESV183xx6T, ESV223xx6T, and ESV303xx6T).
• 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 (in accordance with UL) are listed in section 3.2.1,
Power Connections and in 3.2.3, Control terminals
• Shall be installed in a pollution degree 2 macro-environment.
• NEMA 1 (IP31) models shall be installed in a pollution degree 2 macro-environment.
• All models are suitable for installation in a compartment handling Conditioned Air (i.e., plenum rated).
WARNING!
The opening of branch-circuit protective device may be an indication that a fault has been inter-
rupted. 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.
AVERTISSEMENT!
Le déclenchement du dispositif de protection du circuit de dérivation peut être dы а une coupure
qui résulte d’un courant de défaut. Pour limiter le risque d’incendie ou de choc électrique, examiner
les pièces porteuses de courant et les autres éléments du contrôleur et les remplacer s’ils sont
endommagés. En cas de grillage de l’élément traverse par le courant dans un relais de surcharge,
le relais tout entier doit être remplacé.
NOTE
Control and communications terminals provide reinforced insulation (i.e. considered SELV or PELV,
providing protection in case of direct contact) when the drive is connected to a power system rated
up to 300VAC between phase to ground (PE) and the applied voltage on Terminals 16 and 17 is less
than 150VAC between phase to ground. Otherwise, control and communications terminals provide
basic insulation.
