Rack Installation (Cont.)
Rack-mount Considerations
A. Elevated Operating Ambient
If installed in a closed or multi-unit rack
assembly, the operating ambient tempera-
ture of the rack environment may be greater
than room ambient. Therefore, consideration
should be given to installing the equipment
in an environment compatible with the maxi-
mum ambient temperature (Tma) specified by
the manufacturer (see “Specifications” infor-
mation in this document).
B. Reduced Air Flow
Installation of the equipment in a rack should
be such that the amount of air flow required
for safe operation of the equipment is not
compromised. Do NOT stack other equipment
on the top of the PCS100R unit.
C. Circuit Overloading
Consideration should be given to the con-
nection of the equipment to the supply circuit
and the effect that overloading of the circuits
might have on overcurrent protection and
supply wiring.
D. Reliable Earthing
Maintain reliable earthing of rack-mounted
equipment. Particular attention should be
given to supply connections other than direct
connections to the branch circuit (e.g. use of
power strips).
E. Mains Outlet Earthing
The apparatus with Class I construction must
be connected to a mains socket outlet with a
protective earthing connection.
