Installing the Processor and Modules
CAUTION:
Before unpacking and installing the electronic
modules into the Matrix rack, ensure that all
terminals have been correctly tightened, the rack is
clean and any protective plastic has been removed.
Identify the modules used in the system and separate the processor from the Matrix II modules.
Locate the operator manuals from the processor and modules as these will be required during the
installation process. If different styles of module are planned for racks within the system, refer to the
installation documentation to identify which modules are to be used in each rack.
Installing the Processor
Step 1: Locate the processor module and check that the MCBs on the front panel
are switched off (levers in the down position).
Step 2: Slide the processor into the appropriate wide slot in the front of rack. This
is the top position in a 1.6m rack, and the third row from the top in a 2m
high rack. Do not use excess force if resistance is felt from the connectors.
Remove the unit and check the sockets line up correctly and no pins are
bent. The processor should slide in and connect with its multi-pin
connector smoothly. When in place, the front panel of the processor will be
flush with the surrounding metalwork.
Step 3: Switch all MCBs on (levers to the up position).
Step 4: Observe the processor powering up which, after a short time, will be
displaying the default screen (details are given in the Matrix II Processor
Operator manual) and all three phase on indicators illuminated.
Step 3: Use the screws supplied with the processor to fix the unit in place.
Identifying modules
There is a wide range of modules available with the Matrix II system as listed in pages 2 and 3 , and it
is important to fit them in the correct slot if a selection of modules has been specified with the system.
Each type of module sharing the same capacity and quantity of channels will fit the same appropriate
slot in the rack, but modules of different capacity and quantity of channels are prevented by keyways
in the multipin sockets.
In mixed installations where, for example, sinewave dimmers are specified for particular circuits and
SCR dimmers for others, it is important to ensure they are in the correct slot for operational reasons.
Before starting to install the dimmer modules, check system schematics and design documentation for
a schedule of which module fits in each slot.
