Chapter 5 Main Circuit Terminals MS300 (High Speed Model) Frame F Main circuit terminals: R/L1, S/L2, T/L3, U/T1, V/T2, W/T3, , DC-, DC+/+1, +2/B1, B2, VFD45AMS43AFSHA If you install at Ta 45 ° C above environment, please select copper wire which have voltage rating 600V and temperature resistant 90 ° C or above. If you install at Ta 45 ° C environment, please select copper wire which have voltage rating 600V and temperature resistant 75 ° C or 90 ° C. For UL installation compliant, you have to use copper wires when installation, the wire gauge is based on temperature resistant 75 ° C which is according to the requirements and recommendations from UL.
Do not reduce the wire gauge when using higher temperature wire. 5-10 Models Max. Wire Gauge Min. Wire Gauge Screw Torque (±10%) VFD65AMS23ANSHA VFD65AMS23ENSHA 2 AWG [33.6 mm2] VFD38AMS43ANSHA 6 AWG [13.3 mm2] VFD38AMS43ENSHA VFD38AMS43AFSHA VFD45AMS43ANSHA VFD45AMS43ENSHA
