Installation Manual

Pluggable equipment - Install the socket outlet near the equipment so it is easily accessible.
Rack-mount
– Elevated Operating Ambient - If installed in a closed or multi-unit rack assembly, the
operating ambient temperature 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 maximum ambient temperature (Tma) specified by the
manufacturer.
– 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.
– Mechanical loading - Mounting of the equipment in the rack should be such that a
hazardous condition is not achieved due to uneven mechanical loading.
– Circuit Overloading - Consideration should be given to the connection of the equipment
to the supply circuit and the effect that overloading of the circuits might have on
overcurrent protection and supply wiring. Appropriate consideration of equipment
nameplate ratings should be used when addressing this concern.
– Reliable Earthing - Reliable earthing of rack-mounted equipment should be maintained.
Particular attention should be given to supply connections other than direct connections
to the branch circuit (e.g. use of power strips).
System ground/Safety ground
System (video) ground is indicated by the symbol .
Safety (power) ground is indicated by the symbol
.
The system ground is only used to comply with safety standards or installation practices in
certain countries. Bosch does not recommend connecting system ground to safety ground
unless it is explicitly required. However, if the system ground and safety ground are connected
and grounding loops are causing interference in the video signal, use an isolation transformer
(available separately from Bosch).
!
Caution!
Connecting System ground to Safety ground may result in ground loops that can disrupt the
CCTV system.
Video loss - Video loss is inherent to digital video recording; therefore, Bosch Security
Systems cannot be held liable for any damage that results from missing video information. To
minimize the risk of lost digital information, Bosch Security Systems recommends multiple,
redundant recording systems, and a procedure to back up all analog and digital information.
