3. Environment and Installation
3.1. Wire Gauges and Tightening Torque
To comply with UL standards, use UL approved copper wires (rated 75° C) and round crimp terminals (UL List-
ed products) as shown in table below when connecting to the main circuit terminals. Gefran recommends using
crimp terminals manufactured by NICHIFU Terminal Industry Co., Ltd and the terminal crimping tool recom-
mended by the manufacturer for crimping terminals and the insulating sleeve.

3.2. Wiring Peripheral Power Devices
• After power is shut off to the inverter the capacitors will slowly discharge. Do NOT touch the inverter circuit
or replace any components until the “CHARGE” indicator is off.
• Do NOT wire or connect/disconnect internal connectors of the inverter when the inverter is powered up or
after power off but the “CHARGE”” indicator is on.
• Do NOT connect inverter output U, V and W to the AC power source. This will result in damage to the
inverter.
• The inverter must be properly grounded. Use terminal E to connect earth ground and comply with local
standards.
• It is required to disconnect the ground wire in the control board if the inverter is not grounded.
