Internally Mounted Modutrol IV™ Motor Transformer Kits

SERIES 2—50017460-001, 50017460-003

INSTALLATION INSTRUCTIONS

APPLICATION

The 50017460-001, -003 transformer kits are used to convert line voltage to 24 Vac to power Honeywell Modutrol IV Series 2 motors. The 50017460-001 kit provides 24 Vac isolation, mainly for M734 and M934 replacement motors. See Table 1. Color-coded taps on the transformer primary leads permit selection of 24 Vac, 120 Vac, or 230 Vac to match the power supply. See Table 2. Each assembly includes a transformer and 2 transformer mounting screws. The barrier strip in the motor’s wiring box separates line voltage wiring from low voltage wiring.
