NOTE
THE RECEIVER UNIT SHOULD NOT BE CONNECTED TO LINES CONTAINING EXCESSIVE
POWER UP TRANSIENTS OR CONTINUOUS COMMUTATOR NOISE. A LINE CONDITIONER
MAY BE NECESSARY IN SOME INSTALLATIONS.
4-5.
Wiring Considerations.
1.
Read this manual before installation.
2.
Please observe appropriate local and National Electrical Codes when wiring electrical devices.
3.
Do not connect or disconnect wiring, or perform circuit checks while the power is turned on.
4.
The motor wiring should be in a separate metal conduit from the power wiring, which should also be
in metal conduit.
5.
Low voltage wires shall be wired with proper low voltage class wiring procedures.
6.
Control wiring as well as antenna wiring shall be in separate conduit and shall be kept as short as
possible.
7.
All terminals shall be tightened to specified terminal torque 4.4 IN-LBS (.5 N·m), unless otherwise
specified.
8.
Remove excess metal screws, metal filings and wire clippings from inside of unit.
9.
Inspect to make sure no exposed wire has contact with any other wiring or terminals.
10.
Suppressors are strongly recommended on all contactors.
4-6.
Receiver/Equipment Interface Considerations.
All output relay contacts are rated at 16 amps 250 VAC; however, the system rating for the contacts is 5
Amps. Connection to equipment or contactors with higher voltage or current requirements will require
intermediate relays.
All relay outputs are normally open, momentary contact. Since a relay closure is only active while the
transmitter unit key is pressed and held, devices such as lights or lifting magnet must use a mechanical
auxiliary latching relay.
NOTE
FOR INFORMATION ON INTERFACING WITH SYSTEMS WITH HIGH IMPEDANCE INPUTS SEE
SECTION 6-8. CONNECTING OUTPUTS TO DRIVES OR CONTACT TELEMOTIVE.
4-7.
Receiver Unit Cabinet Mounting.
Mounting brackets are provided. See Figure 4-2. Receiver Mounting Details. Allow room in mounting the
receiver for the door to swing open
Mount receiver unit cabinet securely to mounting surface. Actual cabinet mounting dimensions are shown
on Figure 4-2. Receiver Mounting Details.
4-8.
Receiver Installation.
1.
Normally it should not be necessary to set the access codes, as they are preset. Program the unit for any
special crane configurations or other parameters; if desired, see Section 7. Programming for details.
