CHAPTER-12: UL INSTRUCTIONS
The Axpert-Eazy Series AC Variable Frequency Drives AMT-055-4 to AMT-355-4 complies with
UL508C and CSA C22.2 No.14.
The UL and cUL marks are indicated on the rating nameplate for UL compliant parts.
Observe the following matters when using the inverter as an UL/cUL Standard compatible product.
(1) Use the inverter in an installation environment, where maximum surrounding air temperature does
not exceed 50 Degree C.
(2) For the main circuit connected to the inverter, use a "75°C CU" "voltage rating 600V or higher"
copper wire.
(3) Use the wire sizes given in Table 2-1 for the main circuit wiring. Use a UL/CSA Listed round crimp
terminal, which matches the wire diameter for the terminal connection. Crimp the crimp terminal
with a crimping tool recommended by the maker.
(4) When wiring the circuit, tighten with the torque given in Table 2-1.
(5) Always provide a UL Certified fuse on the input side of the inverter. When protected by Class fuse
as indicated below, these devices have the following short circuit rating.
