Special Considerations for Installations Requiring Compliance with UL Standards
Motor Overload Protection
An external motor overload protective device must be provided by the installer.
OR
Motor overload protection is provided in the controller by means of the thermal device in the motor winding. This
protection cannot be evaluated by UL hence it is the responsibility of the installer and/or the local inspector to
determine whether the overload protection is in compliance with the National Electrical Code or Local Code
requirements.
Branch Circuit/Short Circuit Protection Requirements
Model 584S Type 4 Series
UL Listed (JDDZ) non-renewable cartridge fuses or UL listed (JDRX) renewable cartridge fuses, rated 300Vac or
600Vac as appropriate (depending on the rated input voltage of the drive), must be installed upstream of the drive.
For fuse current ratings, see Chapter 1 “Electrical Ratings - Power Circuit”.
Model 584S Type 5 and 6 Series
UL Recognized Component (JFHR2) semiconductor fuses must be installed upstream of the drive. For fuse current
ratings, see Chapter 1 “Electrical Ratings - Power Circuit”. Refer to Table 1.2 below for recommended
semiconductor fuse manufacturer and model numbers.
