Section 4 – Installation Procedure (Continued)
14
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.

4-7. Receiver Unit Cabinet Mounting.
Mounting brackets are provided. See next page
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 next page Figure 4-2. Receiver
Mounting Details.
4-8. Receiver Installation.
1. Normally it should not be necessary to set
the access codes, they are preset. Program
the unit for any special crane configurations
or other parameters, if desired, see Section
7. Programming for details.
2. Position the receiver. Locate as far as
possible from exposed trolley wire and
sources of electromagnetic or radiated noise.
Cabinet mounting dimensions and mounting
template is on next page see Figure 4-2A
and B. Receiver Mounting Details. Antenna
at top of unit should be kept as clear as
possible of any metal object.
3. Mount the receiver. Mounting brackets are
provided to accommodate mounting on to a
metal strut mounting system. The four deep
mounting holes in corners of the receiver
mounting brackets use quantity four #10-24
combo drive round head screws 1 ½ “ in
length, four #10 lock washers and four #10-
24 hex nuts to mount to the mounting
brackets. Lock washers should be used in
front of hex nuts. Four flat washers are .400
I.D. x 1 ½” O.D. are supplied with use for
mounting the mounting brackets to a metal
strut.
4. Wire the unit using the appropriate electrical
drawings for the specific transmitter and
crane orientation selected, see Section 6.
Wiring. For the Membrane or Pendant
transmitter determine crane orientation; if
the direction pair labeled on the transmitter
better describes the equipment movement.
Use this pair to wire the motor directionals
respectively. If you need to remove the main
board (4 screws) the antenna unplugs from
the RF Receiver, be sure to dress the
antenna cable under the hook on the RF
Receiver when reinstalling the antenna
cable.
5. Wire the power to J1 input power connector.
The connections are Ground (GND), Neutral
(N) and 120 VAC 50-60 Hz (120V). See
Figure 4-1. Input Power Connections.
6. Wiring of the system should now be
complete.
7. Stand clear of the crane and apply AC power
to receiver unit. Turn switch SW2 OFF (MR
relay control) and SW1 ON (main power
switch). Check to see if four LEDs are lit:
(green; DS22, DS23 and DS24) and (red; RF
Receiver ON). If none are lit check AC
power, power switch SW1 and fuse.
