Pluggable equipment - Install the socket outlet near the equipment so it is easily accessible.
Power resupply - If the unit is forced to power down due to exceeding the specified operating
temperatures, disconnect the power cord, wait for at least 30 seconds, and then reconnect
the power cord.
Power lines - Do not locate the unit near overhead power lines, power circuits, or electrical
lights, nor where it may contact such power lines, circuits, or lights.
SELV - All the input/output ports are Safety Extra Low Voltage (SELV) circuits. SELV circuits
should only be connected to other SELV circuits.
Because the ISDN circuits are treated like telephone-network voltage, avoid connecting the
SELV circuit to the Telephone Network Voltage (TNV) circuits.
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.
Notice!
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 losing information, we recommend multiple, redundant recording
systems, and a procedure to back up all analog and digital information.
