Installation Guide for Acuity Brands Factor Series Horticulture LED Lighting System

Quick Guide from the Manual

The Acuity Brands Factor Series is a professional horticulture LED lighting system. Before installation, ensure the power is off. The system requires specific ambient temperature ranges: 32°F-86°F (0-30°C) for VAFS 2, and 32°F-104°F (0-40°C) for VAFS 4, 5, or 6. Mechanical ventilation is required to maintain these temperatures. A critical step for operation is the installation of the shorting cap on the final lightbar in the array; without it, the system will not light.

Safety Warnings

• Electric Shock: Turn off power before installation, inspection, cleaning, or removal. Follow lock-out/tag-out procedures.
• Fire Hazard: Maintain a minimum 3-inch distance from the lightbar and driver to any combustible material. Maintain a 3-inch clearance between lightbars and drivers.
• Installation: The lightbar must be installed lens down with a minimum 6-inch distance to anything below.
• Cables: Do not conceal or extend cables through walls, floors, or ceilings.
• Photobiological Safety: Possibly hazardous optical radiation. Do not stare at the operating lamp.

Components

The system consists of:

• Factor Series lightbars.
• GEPSC210-600 series LED Driver.
• Optional interconnection cables (VAFEX3FT, VAFEX).
• Mounting accessories (Rolling Rack Mounts, Suspended Wire Form Supports).

Mounting Instructions

Rolling Rack Mount

1. Attach the horizontal bracket to the rack strut.
2. Secure the bracket to the strut by tightening the two screws at each end.
3. Place the lightbar on the mount.
4. Use a screwdriver to push down and secure the lightbar onto the bracket.
5. Adjust leveling screws to level the lightbar, then tighten the bottom screws.

Suspended Mount

1. Use two wireform supports (VAFMTSB).
2. Attach supports by pushing them up into the slots on the underside of the lightbar.
3. Suspend the lightbar from the support structure or cables.

Electrical Connections

Important: Do not make or break electrical connections while power is applied.

• Connect the driver output to the first lightbar using a 30-inch interconnection cable.
• Daisy-chain subsequent lightbars using the 6-inch cables.
• Shorting Cap: You must connect the shorting cap to the last lightbar's 6-inch cable. The array will not function without this.
• VAFS 2: Only 2 lightbars should be connected.
• VAFS 4, 5, or 6: A minimum of 4 and a maximum of 6 lightbars can be connected.

Wired Dimming Connections

The system supports 0-10V dimming. To connect:

1. Remove the junction box cover using a #1 Phillips screwdriver.
2. Remove the sealed gland and install a 1/2-inch NPT fitting.
3. Bring dimming network conductors into the fitting.
4. Connect wiring to Dim+ and Dim- terminals.
5. Insulate unused wires (black-white, pink, blue-white, or white-purple depending on driver version).
6. Replace the junction box cover, ensuring the gasket is seated correctly.

Maintenance

To maximize longevity, ensure the lightbar and driver are kept clean and free of dust, oil, or debris. Do not apply film to the lens or cover the driver.
