(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 FR-A802 inverters with the below types of converter unit 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 page
 Wiring protection
For installation in the United States, Class T, Class J, Class CC, or Class L fuse must be provided, in accordance with the
National Electrical Code and any applicable local codes.
For installation in Canada, Class T, Class J, Class CC, or Class L fuse must be provided, in accordance with the Canadian

Rated fuse voltage (V)
Fuse allowable rating (A)
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.
Short circuit ratings
Suitable for use in a circuit capable of delivering not more than 100 kA rms symmetrical amperes, 500 V maximum.
Motor overload protection
When using the electronic thermal relay function as motor overload protection, set the rated motor current in Pr.9 Electronic
thermal O/L relay.
