Bridge Output Channels
45
Bridging Procedure
The steps below describe how to bridge output channels on wall-mount and rack-mount
ArcLamp Driver models. Wall-mount ArcLamp Driver models have four two-position screw-
terminal connections located inside the enclosure. Rack-mount ArcLamp Driver 350 and 700
models have four two-position screw-terminal plugs installed in the back of the enclosure.
Outputs are labeled "LED OUT 1", "LED OUT 2", "LED OUT 3" and "LED OUT 4" (ArcLamp
Driver 150) or "CH 1", "CH 2", "CH 3", and "CH 4" (ArcLamp Drivers 350/700). See the
illustrated examples in
Example Bridge Configurations on page 42
.
1. Set the Output Channel Control Switches
Wall-Mount ArcLamp Driver:
a. Turn off power to the ArcLamp Driver.
b. Using a Phillips screwdriver, remove the two screws securing the lid to the
enclosure.
•
Set the cover and screws aside to reinstall after you complete the briding
procedure.
c. Set switches 2–5 of switch blocks S1–S4 to the same output channel setting for
each set of output channels that you want to bridge. See the explanation and
examples in
Output Channel Control Switches on page 40
Rack-Mount ArcLamp Driver:
a. Turn off power to the equipment rack.
b. Remove the rack-mount ArcLamp Driver to access its cover.
c. Use a Phillips screwdriver to remove the four screws securing the ArcLamp Driver
cover.
d. Set switches 2–5 of switch blocks S1–S4 to the same output channel setting for
each set of output channels that you want to bridge. See the explanation and
examples in
Output Channel Control Switches on page 40
e. Replace the cover on the rack-mount ArcLamp Driver and reinstall the driver in the
equipment rack.
2. Choose a WAGO connector from the bridging kit with at least one more position than the
number of channels to be bridged.
3. Bus the negative poles of the output channel connectors. Output channels are labeled
"LED OUT 1", "LED OUT 2", "LED OUT 3", and "LED OUT 4" on ArcLamp Driver 150 or
"CH 1", "CH 2", "CH 3", and "CH 4" on ArcLamp 350 and 700.
•
Terminate one jumper wire to each negative terminal (“-”) of the output channels to
be bridged, securing each terminal screw onto the fork (wall-mount ArcLamp Driver
350 and 700) or wire (ArcLamp Driver 150 and rack-mount ArcLamp Driver 350 and
700). Tug gently to make sure the wires are secure.
3. Use a free position on the WAGO connector as the negative terminal of the new output
channel. Terminate the neutral wire (typically white) from the installed fixture to the
negative terminal.
•
Run a neutral wire through conduit from the fixture to a free position on the WAGO
connector. Lift up the orange clip, insert the wire, and press the clip down onto the
wire. Tug gently to make sure the wire is secure.
4. Remove any unused wires from the WAGO connector.
5. Use any positive terminal (“+”) from a bridged channel as the positive terminal for the
new output channel. Terminate the line (hot) wire (typically black) from the installed
fixture to the “+” terminal of any bridged channel. For wall-mount drivers, see
and for rack-mount drivers, see
for further instructions on wiring an installed fixture to the output channel “+”
terminal.
6. Wall-Mount ArcLamp Driver: Reinstall the lid with the two screws removed in step 2.
