User Guide
The secondary enclosure kit comprises the enclosure, an internal backplate with DIN rail mounted, and three
25mm conduit connection points: one for the antenna and two for the remainder of the wiring.
Metallic conduit must be bonded together and grounded. The backplane must also be grounded if a 110Vac
supply is used or switched by the MSD.

8.8.3 General Rules for Mounting the MSD
The MCU is designed for DIN rail mounting, is rated at IP30, and must be protected from moisture and dust.
Mount the MCU on a DIN rail in a secondary enclosure (se
) (a suitable option kit is available from
Cattron).
Select a location to minimize any possible interference from RF sources, such as motors. Ideally, install the MSD
enclosure close to the area where the hard-wired E-Stop is located and where it can be viewed easily by users
and maintainers. An approved enclosure with a window is ideal.
All wiring entering the enclosure must be terminated inside the enclosure.
To prevent interference on signal lines do not install high and low voltage cables in the same conduit.
The MSD ships with an external antenna kit. When installing the external antenna keep the antenna cable
separate from all other wiring, both inside and outside the secondary enclosure.
If the MSD is in a stand-alone application i.e. not being used with a PLC, it will be necessary to also have a
suitable DIN rail-mounting 24Vdc power supply (an option available at the time of order).
