(Standard to comply with: UL 508C, CSA C22.2 No.274-13)
 General precaution
CAUTION - Risk of Electric Shock -
The bus capacitor discharge time is 10 minutes. Before starting wiring or inspection, switch power off, wait for more than 10 minutes, and check for residual
voltage between terminal P/+ and N/- with a meter etc., to avoid a hazard of electrical shock.
ATTENTION - Risque de choc électrique -
La durée de décharge du condensateur de bus est de 10 minutes. Avant de commencer le câblage ou l'inspection, mettez l'appareil hors tension et attendez plus
de 10 minutes.
 Installation
The below types of inverter have been approved as products for use in enclosure and approval tests were conducted under the following conditions.
Design the enclosure so that the surrounding air temperature, humidity and ambience of the inverter will satisfy the specifications. (Refer to
 Branch circuit protection
For installation in the United States, Class T, Class J, Class CC, or Class L fuse, UL 489 Molded Case Circuit Breaker (MCCB), or Type E combination motor

Select an appropriate molded case circuit breaker with a rating that is suitable for the size of the cable.

For UL/cUL certification, use the following product.
Model
MMP-T32

Suitable for use in a circuit capable of delivering not more than 50 or 25 kA rms symmetrical amperes, 480Y/277 volts maximum when protected by the Type E
combination motor controllers indicated in the above table.

Type E combination motor controller is combination of Manual motor starter, Short-circuit Display Unit "UT-TU" and Power Side Terminal Cover Kit "UT-CV3".
 Wiring to the power supply and the motor
Refer to the National Electrical Code (Article 310) regarding the allowable current of the cable. Select the cable size for 125% of the rated current according to the
National Electrical Code (Article 430).
For wiring the input (R/L1, S/L2, T/L3) and output (U, V, W) terminals of the inverter, use the UL listed copper, stranded wires (rated at 75
terminals. Crimp the terminals with the crimping tool recommended by the terminal manufacturer.
