Dimmer Room Requirements
Location
o A clean (not dusty) temperature-controlled environment
o Restricted public access to prevent any unauthorised tampering with the dimmer
settings
o Soundproofing or performance area separation to muffle ventilation fan noise.
Please see Appendix B: Matrix Mk.II+ Rack Specifications , for environmental
details.
Ventilation
o The dimmer room requires adequate ventilation to accommodate the heat
generated by the dimming system and to maintain a working temperature of less
than 35degC. For planning purposes allow for a thermal output of 3% of the
available power. Air conditioning is recommended. Ventilation input is through the
rear door grille and a grille at the bottom of the front of the rack. The hot air
exhaust is through the front of each module.
Please see Appendix B: Matrix Mk.II+ Rack Specifications , for environmental
details.
Access to dimmer room
o Before attempting to move the rack(s) into the final position, check access routes
to the dimmer room for space to manoeuvre through doorways and around
corridor corners. Dimmer rack dimensions are provided in Appendix B.
Electrical
o A main circuit breaker cabinet or other readily accessible input power disconnect
device is required. Main breakers which are not located in the same room must
have a physical means to be locked off and disabled.
o It is recommended that during the installation process all disconnected isolation
devices associated with the racks are clearly marked so they will not be switched
on in error.
Floor Surface
o Matrix II racks require a flat, stable and solid floor surface which can
accommodate a load of 1000 kg/m
2
[230lb/ft
2
]. If cable entry is required from
beneath, a plinth with a suitable load carrying capacity is required in advance of
the introduction of the racks to the dimmer room. This can be achieved by using a
computer floor or optional Matrix II rack plinths.
CAUTION:
It is important to ensure that the rack is vertical, as even a minor
amount of structural distortion in the framework can prevent the
modules from being inserted or removed esily. This is particularly
important in the case of swing frame racks, as any distortion of the
chassis frame will prevent the swing frame opening and closing
correctly.
