WARNING 
High Temperature Risk. 
Setting Default Continuous Power for a standard Copley regen resistor to a value greater 
than the default of 65 W may cause the resistor casing to heat to temperatures that could 
cause injury. If higher settings are required, contact Copley Controls customer support. 
Failure to heed this warning can cause equipment damage or injury.
