4. Compliance to UL-standards
Das folgende Kapitel ist aufgrund von UL-Anforderungen in englischer Sprache ausgeführt.
UL Cautions
This section summarizes the items required for UL standard compliant inverter installation.
GENERAL:
WJ series C1 inverter is open type AC Inverter with three/single phase input and three phase output. It is intended
to be used in an enclosure. It is used to provide both an adjustable voltage and adjustable frequency to the AC
motor. The inverter automatically maintains the required volts-Hz ratio allowing the capability through the motor
speed range. It is multi-rated device, and the ratings are selectable according to load types by operator with
keypad operation.
