2.3.7 Instructions for UL, cUL
(Standard to comply with: UL 508C, CSA C22.2 No. 14)
(1) 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 ambient temperature, humidity and ambience of the
inverter will satisfy the above specifications.
Branch circuit protection
For installation in United States, the Class K5 or equivalent for the branch circuit
protection must be provided, in accordance with the National Electrical Code and any
applicable local codes.
For installation in Canada, the Class K5 or equivalent for the branch circuit protection
must be provided, in accordance with the Canada Electrical Code and any applicable
provincial codes.
(2) Wiring of the power supply and motor
Use the UL-listed cables (rated at 75
°
C (167
°
F)) and round crimping terminals to wire
the input (R (L
1
), S (L
2
), T (L
3
)) and output (U, V, W) terminals of the inverter. Crimp the
terminals with the crimping tool recommended by the terminal manufacturer.
(3) Short circuit ratings
Suitable For Use in A Circuit Capable of Delivering Not More Than 65 kA rms
Symmetrical Amperes, 632 V Maximum.
(4) 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".
When connecting two or more motors to the inverter, install external thermal relays for
individual motors
