 Control Circuit Terminal
A UL Listed, Class 2 power supply must be used for the control circuits. See below table.
.
 Interrupting Rating
Varispeed G7 is suitable for use on a circuit capable of delivering not more than 100,000 RMS symmetrical
amperes, 240 VAC maximum (200 V Class) and 480 VAC maximum (400 V Class).
Use a circuit breaker (ELCB or MCCB) or fuses having an interrupting rating not less than 100,000 RMS
symmetrical amperes, 600 VAC maximum.
 Motor Overload Protection
To protect the motor from overload, set the E2-01 constant in the Inverter to the same value as the level of the
motor rated current.
 Compliance with Supplemental Requirements in UL Standards
This product is not equipped with motor overload protection (i.e., a function to retain values from before shut-
down when the power supply is interrupted) that conforms with UL standards (effective as of May 9, 2013).
To make this product comply with UL standards, install a motor overload protection circuit outside of the
product as defined in 430.126, Chapter X, Article 430 of the National Electrical Code (NEC/NFPA 70) of the
United States of America.
To make this product comply with UL standards, install a circuit protection device as defined in 430.52, Chap-
ter IV, Article 430 of the National Electrical Code (NEC/NFPA 70) of the United States of America.

IMPORTANT
The insulation cap must be examined for cracking, tearing or other reduction in the integrity of the insulation
cap certainly after installation. The appropriate size insulation cap shall be used which does not allow slip-
page or require undue force to apply.
