 Low Voltage Wiring for Control Circuit Terminals
Wire low voltage wires with NEC Class 1 circuit conductors; refer to national state or local
codes for wiring. Use a class 2 (UL listed) power supply for the control circuit terminal.
Table 2 Control Circuit Terminal Power Supply

Drive Short-Circuit Rating
This drive has undergone the UL short-circuit test, which certifies that during a short circuit
in the power supply the current flow will not rise above 31,000 Amps maximum at 240 V for
200 V class drives and 440 V for 400 V class drives.
• The MCCB and breaker protection and fuse ratings (refer to the preceding table) shall be
equal to or greater than the short-circuit tolerance of the power supply being used.
• Suitable for use on a circuit capable of delivering not more than 31,000 RMS symmetrical
amperes for 240 V in 200 V class drives (up to 440 V for 400 V class drives) motor
overload protection
 Drive Motor Overload Protection
Set parameter E2-01 (motor rated current) to the appropriate value to enable motor overload
protection. The internal motor overload protection is UL listed and in accordance with the
NEC and CEC.
