2 Installation
All MC components are pre-loaded with all operating software and firmware before leaving the factory so it is
ready to install when you receive it. Before beginning installation, completely read through this section as well
as the following section (3. Power and Wiring) to gain an understanding of the entire installation process.
Consider the installation carefully. Plan the power, signal and control wiring before installing the MC. Also
consider the cabinet space, hardware dimensions, environmental conditions and use good wiring practices to
minimize problems that may occur due to electrical interference.
2.1 Enclosure Guidelines
The MC must be installed correctly for reliable operation. The MC controller is designed for installation within
a suitable enclosure. Do not install the MC outside of an enclosure. Care must be taken when locating
components to ensure that AC power wiring, contactors, starters, relays and other sources of electrical
interference are properly located to minimize their impact on the MC control system.
Particular note should be taken to the position of variable speed drives and switching power supplies. Their
input and load cables should be screened and properly grounded to a central equipment grounding point to
prevent radiated emissions from affecting MC operation.
2.1.1 Locating the MC Touch Screen Interface
It is recommended that the unit be mounted within the front panel of a steel enclosure, through an appropriately
sized opening. Proper enclosure depth is required to insure that there is adequate spacing between the rear
of the interface and the front of any high voltage devices mounted in the enclosure when the enclosure door is
closed. It is required that a minimum separation of 2” be maintained, so plan a depth to accommodate at least
4” (102mm) behind the front of the panel.
WARNING:

To avoid potential electric shock and other hazards, all mounting and
wiring for the MC must conform to the National Electric Code (NEC)
and other locally applicable codes.

Special expertise is required to install, wire, configure and operate the
MC controller. Personnel without such expertise should not install, wire
or operate the MC.
CAUTION:

Prevent metal fragments and pieces of wire from dropping inside the
housing of any MC component. If necessary, place a cover over the
components during installation and wiring. Ingress of such fragments
and chips may cause a fire hazard, damage or malfunction of the
device.

When handling the B42 series loop control boards, use proper ESD
(electro-static discharge) handling procedures to prevent damage to
board components.

Locate the MC and all related control components away from AC
power/motor wiring and sources of direct heat output such as
transformers, heaters or large capacity resistors.
