For opening the casing, you turn
each of the 4 spring-loaded screws

Now the cover can be opened to

connected to the casing).
ATTENTION:
When opening the
cover, make sure not to damage the
connection film (3) between casing
and cover and the flat cable (4) to
the membrane keys (see illustration

Ill. 1: Casing of RZ-24 central
4b) Opening the Casing
The RZ-24 central is the power supply with integrated tripping device of
the DICTATOR hold-open system on fire doors, smoke evacuation flaps
etc. also in
hazardous areas.
When using the RZ-24, it is mandatory to respect in addition to the re-
gulations for hazardous areas also the regulations of the general type
approval Z-6.500-2443.
The RZ-24 central itself is not ex-proof and
therefore must be moun-
ted outside the hazardous area
.
When choosing the mounting place, please make sure that
- the indications on the cover of the casing are clearly visible,
- the keys can easily be reached,
- the warning of the horn can well be heard.
Furthermore you have to pay attention to the IP rating of the casing which
is required for the choosen mounting place.
By default the casing of the RZ-24 central has 4 borings with M16 thread
for the included cable inlets IP 64. When these are used, the whole casing
corresponds to the IP rating IP 64 (when mounted with the cable inlets
pointing downwards!).
IMPORTANT:
After mounting, all not used cable inlets have to be closed
professionally according to the required protection type (blind plugs)!
