Installation Notes
The MPC is a microprocessor-based controller that uses electro-static
sensitive CMOS components. Do not make any (low or extra-low
voltage) electrical connections without adequately grounding the MPC
and the worker to eliminate an electro-static charge between the two. A
conductive wrist strap worn by the worker and attached to the MPC
enclosure is adequate to satisfy this requirement.
Conduit connections can carry fluids and vapors into the MPC causing
damage and void the warranty. Care should be taken when installing
conduit to protect against fluid/vapor entry. If necessary, provide sealed
entries or conduit drains near the point of entry. The controller comes
equipped with liquid-tight connectors for signal cable entry points. The
user must supply the correct connection for the power entry, as per the
local codes and requirements. Any cable entrances that are not used
should be appropriately sealed against moisture and vapors.
The safety of any system incorporating the MPC is the responsibility of the
assembler of the system.
