Output Wiring - Emerson HVAC Drive H300 Installation And Commissioning Manual

Connect the main power supply, motor and control wiring using the following
recommended conduit locations. The input phase sequence does not affect the
output phase sequence of the VFD. It will affect bypass sequence and motor rotation
direction.

2.5.3 Output Wiring

The electronic bypass package is always supplied with a Class 10 motor O/L on its
output. However, the unit may be supplied with several different output options. The
following output options are available.
• Single motor O/L (Terminals T1, T2, and T3)
• Dual motor O/L (Terminals (Motor 1 – T1, T2, and T3)
(Motor 2 – T4, T5, and T6))
• Output reactor
Note: All contactors and relays supplied in the electronic bypass package are
suppressed with R/C snubbers. If adding additional inductive loads (i.e. magnetic
contactors, magnetic relays, magnetic valves, solenoids, magnetic brakes, etc.) in or
near the electronic bypass package, use an appropriate surge suppressor across the
coils to limit the transients on the supply lines.
