The MACH C3000/C4000 boiler power block is located in the junction box in the front of the boiler, at the lower left
corner (pictured to the right). This junction box houses the transformer, the fuses, the power block terminal strip
circuit breakers, and the blower relay.
The three space terminal strip circuit breakers are mounted on DIN rail and are for connection of the three power
wires. There is an additional space on the DIN rail for a ground connection. This boiler requires either 208-240 V,
three phase, 60 Hz or 480 V, three phase, 60 Hz. The boiler requires a dedicated ground wire. Do not ground
through the conduit.
