Oct 22, 2026

Upload by fresh2021

SmartVFD Three Contactor and Three Contactor Auto-Bypass Assemblies installation instructions explain how the bypass assemblies route electrical power through or around a variable frequency drive (VFD). The guide covers application verification, pre-install checks, required trained technician qualifications, and safety warnings including disconnecting power before work. It specifies location, ventilation and ambient temperature limits, branch protection, copper wiring requirements, and detailed three-phase wiring and jumper configurations for auto and manual bypass, plus grounding and correct parameter setup during operation.

SmartVFD Three Contactor and Three Contactor Auto-Bypass Assemblies INSTALLATION INSTRUCTIONS APPLICATION Three Contactor Bypass The Smart VFD Three Contactor Bypass Assemblies channel electrical power either through or around the variable frequency drive (VFD) . INSTALLATION When Installing This Product 1. Read these instructions carefully. Failure to follow them could damage the product or cause a hazardous condition. 2. Check the ratings given in the instructions, Honeywell SmartVFD manual’s and on the product to make sure the product is suitable for your application. 3. Verify bypass model is correct; no damage has been incurred; no screws, connections, terminations are loose. 4. Installer must be a trained, experienced service Technician, with VFD operation experience. 5. After installation is complete, check out product operation as provided in these instructions. WARNING Can Cause Serious Injury or Death 1. Installation requires work with voltages that may cause serious injury or death. 2. This instruction manual is intended as a guide only. End user is responsible for proper application of this assembly, insuring proper conformance, directives, intended use and maintaining all safety practices as described in Honeywell SmartVFD manual, local codes, and local safety authorities. 3. Disconnect power supply before installation, and before any servicing. CAUTION Equipment Damage Hazard. Can short equipment circuitry. Disconnect power supply before installation Location and Mounting Locate the device in a clean, dry, well-ventilated area with an ambient temperature below 104°F (40C) . Refer to SmartVFD user manual for free air space requirements above and to the sides of SmartVFD’s. Insure proper branch/short circuit protection is provided. WIRING IMPORTANT All wiring must agree with applicable codes, ordinances and regulations. Variable frequency drive can store energy. Refer to VFD manual for safe work practices and appropriate wait times before servicing after equipment power has been de-energized. All safety, warning and caution information located in Honeywell SmartVFD manuals must be read, understood and followed. 1. Ensure that bypass panel voltage corresponds with that of the power supply. 2. To access the bypass panel wiring compartment: a. Ensure the main disconnect handle is in the OFF position. b. Open the cover. c. Test for power. 3. Refer to SmartVFD user manual “Power Cabling” and“Control Unit” for proper power and control wire sizing information. 4. Terminate input three phase power wiring to line side of main fused disconnect. Refer to bypass panel schematic. 5. Terminate three phase motor wiring to motor terminals “T1”,“T2”,“T3”. Refer to bypass panel schematic. 6. Terminate VFD control wiring to proper terminal in bypass panel. Refer to bypass panel schematic. 7. If equipped with Auto bypass, leave jumper J2 on bypass panel terminals 4 & 5 for auto bypass operation. Remover jumper J2 for manual bypass operation. 8. Leave jumper J1 on bypass panel terminals 1 & 3 if fire/smoke/safety shutdown not used. If this shutdown is used, remove jumper J1 and terminate fire/ smoke/safety shutdown to bypass panel terminals 1 & 3. Refer to schematic for typical wiring. IMPORTANT Use only copper wire with 167 °F (75 °C) minimum. 62-2032-02 SMARTVFD THREE CONTACTOR AND THREE CONTACTOR AUTO-BYPASS ASSEMBLIES OPERATION 1. Make sure bypass panel and motor are properly grounded. 2. Make sure all connection points are tight, including all bypass panel connection points. 3. Make sure all safeties (customer’s option) are connected and in working order. 4. Double-check correct voltage is being applied and power and motor wiring are terminated in the correct place. 5. Verify motor FLA does not exceed VFD output amp rating and bypass starter overload relay setting dial. 6. Set bypass starter overload relay adjustment dial to

FAQs

What must be verified before installation of the SmartVFD bypass assembly?

Confirm the bypass model is correct, check for any damage, and ensure no screws, connections, or terminations are loose. Verify the ratings match the product and the intended application.

What safety steps are required before wiring or servicing?

Disconnect the power supply before installation or any servicing, and confirm personnel and debris are clear before applying power. Follow SmartVFD manual safety, warning, and caution information and allow appropriate wait time for stored energy to dissipate.

How is wiring handled for auto bypass versus manual bypass?

For auto bypass operation, leave jumper J2 on bypass panel terminals 4 and 5. For manual bypass operation, remove jumper J2. Jumper J1 on terminals 1 and 3 is used unless fire/smoke/safety shutdown is required, in which case it must be removed and shutdown wiring connected.
