4 INSTALLATION
4.1 CHOOSING A MOUNTING LOCATION
There are a few items to consider when selecting a location to install the MCU enclosure.
First, the MCU enclosure must be installed in a location that allows easy access for
maintenance and service. Adequate clearance must be allowed to remove the cover for
access. The location must also provide adequate RF reception range and a clear ‘line of sight’
to the transmitter.
Select a location to minimize any possible interference from RF sources such as motors.
Ideally, the MCU enclosure should be installed as close as practical to the controlled
machine’s electrical cabinet with a minimum of 48 inches clearance from obstructions in front
of and on either side of the enclosure. If this clearance is not possible, the installation must be
tested to ensure that interference does not impact the system’s performance. Contact the

service department for more information or for help in resolving any problems –

All wiring entering the enclosure must be terminated inside the enclosure. Do not install any
pass-through wiring.
To prevent interference on signal lines, do not install high and low voltage cables in the same
conduit. The standard MCU is shipped with an internal antenna. However, if an optional
external antenna is required, keep the antenna wire separate from all other wiring, both inside
and outside the MCU enclosure.
Figure 7 overleaf shows the mounting footprint drawings for both types of IP 67 MCU
enclosures.
Note that optional shock mounting brackets are available. Contact the factory for this option -
