Wiring

WARNING
Hazardous Voltage w/Capacitors!
Disconnect all electric power, including remote
disconnects and discharge all motor start/run capacitors
before servicing. Follow proper lockout/tagout
procedures to ensure the power cannot be inadvertently
energized. For variable frequency drives or other energy
storing components provided by Trane or others, refer to
the appropriate manufacturer's literature for allowable
waiting periods for discharge of capacitors. Verify with
an appropriate voltmeter that all capacitors have
discharged. Failure to disconnect power and discharge
capacitors before servicing could result in death or
serious injury.
For additional information regarding the safe discharge
of capacitors, see PROD-SVB06A-EN.
NOTICE
Starter Damage!
Use of power factor correction or surge capacitors on
the load side of the starter will result in serious damage
to the starter that will NOT be covered by the starter
warranty. The capacitors MUST be connected to the
line side of the starter. The up-to-speed (UTS) contact
can be used to energize the capacitors after the motor
has reached full speed. Do NOT connect the capacitors
between the starter and motor. See RTHC-SVD02*-EN
for further details.
Low Voltage
The next step is the interconnecting wiring between the
existing controls and the new Benshaw Redistart starter.
Each unit specific chapter includes a basic schematic
showing the necessary wiring for the controls. Use the
same wire size that was used for the original wiring.
Note: 14 gauge wire is sufficient for most applications.
Adhere to all state and local electrical codes.
High Voltage
Wire the high voltage/power supply from the starter to the
compressor. Use the specified Starter Power Lead Kit
listed in Table 7, p. 47. Follow the schematic in unit
specific chapters.
