4.3 WIRING DIAGRAM - IPVB 350 - 500
IPVB 350 can operate at either 3x208-230 VAC or 3x440-
480 VAC (default) based on the configuration of the terminals
in the motor junction box.
The motor wiring terminals shown in Fig. 9 shows default
jumper positions for 3x440-480VAC operation. If the
application requires 3x208-230VAC operation, the jumper
positions must be changed according to Fig. 10.
Verify power supply voltage and motor terminal
configuration BEFORE connection to fan.
