Changing And Replacing Light Bars And Modular Use; Installing The Fixture; Connecting The Manual Dimmer Or External Lighting Controller - Lumatek ZEUS 600W 2.6 Handbuch

6.4 Changing and replacing light bars and modular use

The LED fixture's modular design uses an intelligent LED driver which can decrease or increase power to match
the amount of 100W light bars installed in the fixture automatically. If not all light bars are required, the driver
will only draw power required for the amount of light bars connected eg if three light bars are connected the
driver will only draw 300W to power them.
Warning! At least one light bar must be installed in the fixture before switching on.

6.5 Installing the fixture

Warning! Mount the system to something that can hold the weight of the LED fixture.
Ensure all light bars are installed correctly and are secure. Carefully turn the fixture over and attach the metal
cable hangers to the mounting hooks. Hang the fixture in required position and height. For optimal perfor-
mance; position fixture 30 - 50cm above plant canopy for a 1.4 x 1.4m light spread. Ensure the fixture is hung
horizontally.

6.6 Connecting the manual dimmer or external lighting controller

The dimmer control or lighting controller is connected to the 'SIG IN' connector on the fixture frame. This
enables light intensity (PPF output) to be adjusted according to requirement. The LED fixture light
intensity can be adjusted without changing relative spectral power distribution or losing efficiency.
Remove dust cap and ensure male & female connectors are correctly aligned and then push together
until click-locked. To disconnect; turn twist-lock anti-clockwise and pull apart.
