In each kit you will find the following – please Contact Us if there are any parts missing:
2 x High Light 420 LED grow panels
1 x Anodsised aluminium Heatsink (960mm x 206mm)
1 x Mean Well HLG-320-48 A driver (340W Kit) or HLG-480-54 A driver (470W Kit) with quick-release waterproof male connector
2 x Black cable ties
1 x 4.5m German LAPP cable with quick-release male and female waterproof connectors
1 x Dual TE plug splitter (loom) with quick-release female waterproof connector and 16mm locking ring
24 x M3 mounting screws
2 x High Light Stainless Hangars
LED Panel to Heatsink
The High Light 420 LED panels can be screwed to the heatsink using the supplied M3 screws at any time during assembly as long as you are careful not to rest the LEDs face-down.
DO NOT REST LEDS ON ANY SURFACE
Orientate the panels so that the connector ends are in the middle of the heatsink, facing the 16mm connector hole. Use the black circles in the middle of the panel as a guide to centering the screws so that the panel fits exactly on to the heatsink. Tighten screws until they are snug, but not overly tight.
There is a risk of damaging the LEDs when you screw the boards to the heatsinks. Ensure that the screwdriver is the correct size and hold the screw with thumb and forefinger whilst tightening to prevent the screwdriver from jumping out of its slot and hitting an LED. Work slowly and carefully.
If there is any risk of damaging the LEDs during assembly, please move on to the next steps first and mount the High Light 420 panels to the heatsink last.
Push the white TE connectors through the 16mm hole in the middle of the heatsink one connector at a time (don’t try to push both through at once – they will not fit). Once the main body of the loom is in place, push the white connectors through the 16mm locking nut (one at a time) and then thread the locking nut onto the black connector body and tighten with your fingers.
DO NOT OVERTIGHTEN LOCKING RING
Only tighten plastic ring with a spanner 1/4 of a turn so that it is snug. If you overtighten, you make damage plastic threads.
Connect High Light 420 Boards
Once LED panels are in place, you can connect them. Be careful to hold each board connector with one hand as you push the plug in until it snaps into place. The plug will be a tight fit and it is important that you hold the connector on the board when plugging and unplugging to ensure it does not break from excessive force.
Once connected, you may use the supplied cable ties to hold the wiring loom in place. Push the cable ties through the 4mm holes in theheatsink and secure the wiring. The finished connectors should look like the photo above.
Connect the Driver
Driver cable plugs straight into the back of the heatsink. There is a quick-release tab on top of each cable connector that can be pressed down to release the connector. The male end of the driver cable plugs into the fixture whilst the female end plugs into the driver.
DO NOT PUT PRESSURE ON CONNECTOR
Ensure that driver cable is not bent at an excessive angle so as to put unwanted side pressure on the connector fitting.
Connect an External Dimmer
If you have bought the optional Mean Well AB driver with an external Dimmer, simply conect the blue wire to the positive (+) terminal and the white wire to the negative (–) terminal. Note: Dimmer is not waterproof, so please keep away from moisture.
No Dimmer, No Problem
If you do not wish to use an external dimmer with an AB driver, place each of the supplied heatshrink caps over the blue and white dimmer wires and use a heat source (hair drier, cigarette lighter, gas burner etc) to shrink the caps and seal the wires. Once properly shrunk, wires will be waterproof. You may notice small globs of clear glue at each end of the caps after being heat-shrunk – this is normal.
You can adjust the voltage (Vo) and current (Io) on the driver by removing the black rubber dust caps and inserting a small screwdriver (phillips head or flathead) into each slot.
On some drivers (ELG, XLG) the adjustment dials are on the bottom of the driver. On HLG drivers the dials are on top.
Locate internal dial with screwdriver and GENTLY turn clockwise to set maximum voltage and current. Turn anti-clockwise to dim. Normally voltage (Vo) is set to maximum and current (Io) is used to dim. If further dimming is required, voltage can also be dimmed.
When both Vo and Io dials are set, the optional external dimmer (potentiometer) can be used to dim the driver. Please note that the onboard dial will set the maximum current and that the external dimmer will not exceed this setting. If more current is required, the onboard current dial must be increased.
Do not force dials. If resistance is encountered (hard stop), then dial is set to maximum (clockwise) or minimum (anti-clockwise).
