3.5. Electrical
Installation
The laser unit interface cable and all other wiring should be run in separate 1/2" or 3/4" conduit. Do not
run any other cables in the same conduit with the laser head cable.
A suitable disconnect should be provided by the installer.
Run conduit between the laser support unit and the crane's control panel.
Run conduit from the LSU to about 1 ft. from the laser. Putting a slight downward bend in the conduit at
the laser transceiver will help keep dirt and water out. Place a protective end piece on the open end of the
conduit to protect the laser cable from sharp edges.
Pull the supplied laser cable by the end that does not have a connector on it through the conduit, starting
from the opened laser unit end and into the LSU. Leave enough cable on the laser end so that it is twice
as long as the distance between the end of the conduit and the laser unit (about 2 ft. to 3 ft.). This will
produce a service loop, which will also help keep dirt and water out of the open end of conduit (refer to
Figure 9). This cable consists of four wires. See Figure 10 through Figure 12 for wiring information for this
cable. Plug the connector into the laser unit. The connector is keyed; do not force.
