3.7 RECEIVER UNIT ENCLOSURE MOUNTING
When mounting the receiver, make sure to allow room for the door to swing open if it is mounted within an
enclosure. Mount the receiver unit cabinet securely to the mounting surface.
3.8 RECEIVER INSTALLATION
1. Be sure to mount the receiver antenna in direct line-of-sight of the operator and free from all
obstructions. Refer to Section 3.4 for recommendations regarding antenna mounting.
2. Do not mount the receiver near high levels of electrical noise, such as unshielded variable
frequency drives, as they may cause minor interference. When mounting the Flex M near
unshielded variable frequency drives Magnetek typically recommends that the Flex M and all
antenna cable routing be mounted a minimum of 24 inches from all unshielded variable frequency
drives and cables.
3. Allow adequate room for mounting the receiver. Be sure to allow a minimum of 5” between the
connector and nearest surface to allow for cable harness connections.
4. For best reception, and to help protect connectors from moisture and water damage, mount the
receiver in an upright position.
5. If obstructions cannot be cleared, or if the unit must be mounted inside of a metal enclosure, the
remote antenna should be used.
6. Do not enclose the antenna in steel. If the receiver is mounted within an enclosure, an external
antenna MUST be used. For the best reception, keep all metal objects away from the antenna.
Consult the factory for more information regarding your application.
7. The power source to the Flex M system must have a master disconnect and should be fused.
8. It should not be necessary to set the Access Code or channel, as they are preset. If special field
programming is needed, power the unit up on the bench and program the unit for any special
configurations or other parameters (see Section 5 for details). The unit can be re-programmed
after it is installed if necessary.
9. Position the receiver; make sure to locate it as far as possible from exposed trolley wire and
sources of electromagnetic or radiated noise.
