Power wires (line wire (hot) and neutral wire) from the
installed fixture are terminated to the provided two-
position screw-terminal connectors preinstalled in the
output terminals on theArcLamp Driver. Termination is
available for up to four uniquely addressable outputs
(channels).
Note:
Power wiring should only be installed
and terminated by a qualified electrician and
should follow standard wiring installation
practices.
1. Make sure rack power is off.
2. See
Wire and Terminal Specifications on page 26
for specification of wire, strip length, and
terminal torque ratings. Prepare the wires accordingly.
3. Terminate neutral and line (hot) wires to an output.
a. Run a neutral wire (typically white) and a line wire (typically black) through conduit
from the fixture to the rack and route it to the ArcLamp Driver output terminals.
Output channels are labeled CH1, CH2, CH3, CH4.
b. Loosen the terminal screws on the provided two-position screw-terminal plug.
c. Terminate the neutral wire to the “-” terminal, securing the terminal screw onto the
wire.
d. Terminate the line (hot) wire to the “+” terminal, securing each terminal screw onto
the wire.
e. Tug gently on the wires to ensure they are secure.
Bridging Output Channels
It is acceptable to bridge multiple output channels together, ganging the maximum output
allowed into a single combined output channel. See
Bridge Output Channels on page 37
for
examples of the configurations made possible by bridging output channels.
For example, bridging all four output channels on an ArcLamp Driver 350 or two channels on an
ArcLamp Driver 700 creates a single bridged output channel that can support 60 ArcLamps. 60
ArcLamps on a bridged channel draw about 8 A, allowing the single bridged channel to support
the large number of ArcLamps.
Note:
This installation technique reduces the number of available output channels.
See
Bridge Output Channels on page 37
.
Note:
A maximum of two output channels can be bridged together on an
ArcLamp Driver 700 (standard or emergency model).
