3.4 Electrical Conduit Installation
The laser sensor cable and all other wiring should be run in separate 1/2 in. or 3/4 in. conduit. Do not run
any other cables in the same conduit as the laser sensor cable.
The installer should provide a suitable disconnect to allow a controlled power-down.
Run conduit between the laser sensor and the crane’s control panel. 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.
Locate the supplied laser cable by the end that does not have a connector on it. Pull the cable through the
conduit, starting from the opened laser sensor end. 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 [0.6 m to 0.9 m]).
This will produce a service loop, which will also help keep dirt and water out of the open end of the conduit.
See Figure 3-15 and Figure 3-16 on page 33 .
This laser cable consists of four wires. See Figure 2-1 on page 15 for wiring information for this cable.
Plug the connector into the laser sensor. The connector is keyed; do not force it.
