Quick-Start Guide
1.4 Control Module Installation
A rack or panel mounted chassis will be required when installing any Zero Two Series
Module. These chassis' should be mounted in non-hazardous, weather-protected
locations and should be subjected to minimal shock and vibrations. The rack and panel
mounted chassis are available in 4, 8, and 16 channel sizes. Multiple 16-channel
chassis may be connected to each other to form larger systems.
In installations where two or more module types are to be mixed in the same chassis,
ensure that the individual coding strips match the channel application. The coding
strips are pre-configured at the factory and the male portion is already on each module.
The female portion, if un-mounted, must be fastened into position on the mounting strip
of the desired chassis channel so as to mate with its counterpart on the module (see
Figure 1).

NOTE - Zero Two series modules require air circulation to avoid excessive heat build-
up. If chassis are stacked vertically within an enclosure, forced air circulation may be
required. The Control Modules are, to a great extent, immune to electromagnetic
interference (EMI). However, they should not be mounted in close proximity to radio
transmitters or similar equipment.
