2.3.7 Instructions for compliance with the UL and CSA standards

(Since we obtained the approval of the UL and CSA Standards from the UL, the products conforming to the
Standards carry the UL and cUL marks.)
( 1 ) Installation
The above types have been approved as products for use in enclosure and approval tests were conducted
under the following conditions. In enclosure design, refer to these conditions so that the ambient temperature
of the inverter becomes 50°C or less.

( 2 ) Wiring of the power supply and motor
Use the UL-approved power supply and round crimping terminals to wire the input (R, S, T) 〈L
(U, V, W) terminals of the inverter. Crimp the terminals with the crimping tool recommended by the terminal
manufacturer.
( 3 ) Fuse
On the input side, use any of the UL Class K5 fuses having the ratings as listed below:
