11. Connecting fixtures to the PSU
The KNV PSU drives up to five (5) KNV Dot fixtures or one (1) KNV Line fixture at each of
its five power/data outputs. In other words, one KNV PSU can drive up to 25 pixels.
Important! The maximum permitted distance from a PSU power/data output to the last
device on a power/data link is 50 m / 164 ft.
The KNV Dot and Line system’s power/data connections are hot-pluggable, but it is still
good practice to shut down power to the PSU before cabling and connecting KNV
fixtures.
To connect KNV Dot or Line fixtures to the PSU:
Shut down power to the installation.
Obtain enough KNV 6-pin ODS DC power/data extension cables from GLP to
create a cable run from each PSU output to either:
• the first of up to five (5) interconnected KNV Dots or
•
one KNV Line.
Removing rubber sealing caps from connectors where necessary, connect
data/DC power extension cables to the PSU and to the KNV Dot fixtures or KNV Line
fixtures.
In outdoor installations or any installation where there may be water projections or
high humidity levels, check that all unused connectors are sealed with their caps.
Install rubber seals on the unused THRU cable tails of the last KNV Dot in each group
of Dots.
Do not allow any weight (in the form of cable runs, for example) to hang from
connectors, as this may affect their sealing ability and allow water to enter
connections.
