 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.
WARNING
Operation of this equipment requires detailed installation and operation instructions provided in the installation/Operation
manual intended for use with this product.
WARNING
The opening of the branch-circuit protective device may be an indication that a fault current has been interrupted. To reduce
the risk of fire or electric shock, current-carrying parts and other components of the controller should be examined and replaced
if damaged.
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

 Installation
The below types of inverter have been approved as products for use in enclosure.
Design the enclosure so that the surrounding air temperature, humidity and ambience of the inverter will satisfy the
specifications. (refer to
 Branch circuit protection
Short circuit protection of the inverter cannot be used as branch circuit protection.
For installation in the United States, the semiconductor fuses shown in the following table must be provided, in accordance
with the National Electrical Code and any applicable local codes.
For installation in Canada, the semiconductor fuses shown in the following table must be provided, in accordance with the

*1 "xx" in a model name is "41, 46, 51, or 56".
 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) terminals of the converter unit and output (U, V, W) terminals of the inverter, use the UL
listed copper, stranded wires (rated at 75°C) and round crimp terminals. Crimp the terminals with the crimping tool
recommended by the terminal manufacturer.
