11.3 Conditions of utilization for UL certification 638B
Temperature rating of field installed conductors shall be at least 60/ 75°C. Use copper
Conductors only.
Only for use in WYE 480/277V or 400V/230V supply sources.
Suitable for use on a circuit capable of delivering not more than 5000 rms symmetrical
amperes, 480V ac maximum when protected by Branch circuit protection as below.
These Device needs Branch Circuit Protection (BCP) with the following nominal fuse ratings:

UL listed (JDDZ) Fusible cut-out Class J or Class CC.
PARKER Hannifin recommends Bussmann LPJ-Series or Littlefuse JTD-Series.
The maximum surrounding air temperature is 40°C.
The drive provides internal motor overload protection.
This must be set so that 600% of the nominal motor current is not exceeded.
Integral solid state short circuit protection does not provide branch circuit protection. Branch
circuit protection must be provided in accordance with the National Electric Code and any
additional local codes.
Aux. Control circuits for connection to “class 2” power supply only.
The device are only to be installed in a degree of contamination 2 environment (maximum)
During the UL evaluation, only Risk of Electrical Shock and Risk of Fire aspects were
investigated. Functional Safety aspects were not evaluated.
Motor overtemperature sensing is not provided and is required at installation.
For 638B10 and 15A-Type: With S1 full load operation > 5,5KW the linechoke Block
Transformer-Elektronik GmbH LR3 40-4/16 has to be used.
