2-2.2.2.3. Multipoint Module. The GENII MP REM Multipoint Module is a
DIN Rail-mounted device that provides input/output expansion capability for the
associated Genesis II Digital Controller or GENII MPC. It is designed to be located at a
remote location. The GENII MP REM is enclosed in a square case made of flame-
resistant Astrene M650 IR plastic. It is identical in appearance and dimensions to the
GENII MPC (Figure 2-3).
NOTE
Unless otherwise noted, Installation Instructions are based on the
assumption that the system to be installed is a local Genesis II System
consisting of one Genesis II Digital Controller and three types of
LEMs. Installation Instructions for other types of hardware, such as:
Genesis I Digital Controllers, GENII MPCs, and REMs are contained
in Paragraph 2-4 - Difference Data.
2-3. INSTALLATION INSTRUCTIONS.
A steel enclosure is recommended to contain the system with the aim of minimising EMI from
surrounding equipment. To facilitate the number of cables entering and leaving the enclosure, the
minimum dimensions of slotted cable ducts should be 45mm x 45mm with 65mm clearance from
the cable ducts to the terminals of the units.
Where LEMs are used, every effort should be made to locate these units adjacent to the controller
to minimise problems with connecting cables due to the critical lengths and segregation
requirements.
The communications cable between the Digital Controller and the LEMs is an Innotech-
manufactured item; part number GenII LEM Cable. The cable is made in 150mm segments;
therefore, it is important that the LEMs are located as close as possible to the Digital Controller
and placed side-by-side on the DIN rail.
Figure 2-8 shows an example of a typical Genesis System layout in an equipment enclosure.
