• This equipment is considered Group 1, Class A industrial
equipment according to IEC/CISPR 11. Without appropriate
precautions, there may be difficulties with electromagnetic
compatibility in residential and other environments due to

• Be careful when stripping wires. Wire fragments that fall into the
controller could cause damage. Once wiring is complete, make
sure the controller is free of all metal fragments before removing
the protective debris strip.
