6 Installation
6.1 Free Standing
The HUB24 is primarily convection cooled, with the main air intake at the bottom and
air exhaust at the back and sides - these openings must not be obstructed.
Correct positioning and adequate ventilation are essential. The HUB24 must be in the
upright position, standing on its feet. Allow at least 100mm behind, at least 200mm
above and at least 100mm on each side of the dimmer.
Allowing for good airflow will serve to further reduce internal dimmer temperatures and
will enhance the dimmer’s operational reliability.
6.2 Wall Mounting
The HUB24 may also be wall mounted in non-enclosed spaces. Mounting within
cupboards is not recommended.
When wall mounted, allow at least 300mm above and at least 100mm on each side of
the dimmer. It should be at least 200mm from the floor to avoid excessive ingress of
dust and fluff.
Multiple HUB arrays should be spaced vertically with at least 300mm gap between the
dimmers and no more than three dimmers high, to avoid excessive heating of the top
dimmer. Horizontally there must be at least 150mm space between each dimmer.
The wall mounting bracket is an optional accessory. Place the wall mounting bracket
against the wall, orienting it so the tabs are at the top. Mark and drill at least four fixing
points and attach the bracket to the wall.
The HUB24 is attached to the pre-mounted bracket as follows:
1. Pull out the three phase cable from the cable tray.
2. While tilting, lift the HUB24 up and insert the tabs through slots in the top of the
rear panel.
3. Pivot down the HUB24 fully onto the bracket, being careful to position the three
phase cable in the cable groove.
4. Lock the HUB24 in place with two M4 screws through the bottom of the bracket.
