Variable Frequency Drive Option (VFD)

￿WARNING

Control and LineVoltage!

Control and line voltage wiring from the VFD to the unit must be in accordance with all local and National Electric Codes. Do not touch circuit components until main power has been turned off and “charge” lamp is extinguished.The capacitors are still charged and could

result in death or serious injury.

Mounting Requirements

Proper location of theVFD is important to achieve proper performance and normal operating life. Installation must be in an area where it will be protected from:

•Direct sunlight, rain or moisture.

•Corrosive gases or liquids.

•Vibration, airborne dust, or metallic particles.

For effective cooling as well as proper maintenance, install theVFD vertically to the ground using four mounting screws.

There must be a minimum eight inch clearance above and below theVFD. A minimum two inch clearance is required on each side.

Also, allow enough clearance for opening theVFD cabinet door.This will ensure sufficient air space for cooling.

Refer to the “Dimensions andWeights” section beginning on page 19 forVFD dimensions and weights.

￿WARNING

HazardousVoltage w/Capacitors!

Disconnect all electric power, including remote disconnects before servicing. Follow proper lockout/tagout proce- dures to ensure the power cannot be inadvertently energized. For variable frequency drives or other energy storing components provided byTrane 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.

Note: For additional information regard- ing the safe discharge of capacitors, see

PROD-SVB06A-EN or PROD-SVB06A-FR.

NOTICE

Use Copper Conductors Only!

Unit terminals are not designed to accept other types of conductors. Failure to use copper conductors may result in equipment damage.

The variable frequency drive (VFD) option can only be used with IntelliPak units.The VFD andVFD w/bypass is available from

5to 25 hp and is aTraneTR1. AllVFD’s are pre-configured and run tested at the factory prior to shipping.TheVFD is wall mounted.
