2.0 Installation Instructions:
1. The receiver should be mounted in a location that is convenient to the control box and is
securely attached to the equipment. The receiver is mounted by drilling four ¼” (6mm) holes
(see diagram below). Mount the receiver using the supplied hardware. It is best to keep the
receiver as far away as possible (approximately 6 feet) from variable frequency drives and the
motors and cables attached to them to avoid interference.

2. The receiver wires are numbered. The wires are identified on the label on the top of the
receiver.
3. All the contacts in the receiver are “dry” relay contacts. This means that is there is no internal
source of power to the contacts. You will need to connect the “common” lead for each output
or set of outputs that you plan to use to the same power supply that it would be connected to in
a corded pendant. For most cranes this wire is X1 (the 120 volt AC control transformer “hot”
side). Some cranes have separate hoist/trolley and bridge transformers. In these cases,
connect each transformer’s X1 to the function(s) it powers. There is no requirement that the
common leads be connected to a 120 volt AC supply- these are “dry” relay contacts; whatever
you put into the common wire, comes out each function’s wire when that relay closes. The
only restrictions are, do not exceed 10 amps or 250 volts AC. For DC applications call the
factory at 1-800-382-3558.
