Electrostatic-sensitive device - Use proper CMOS/MOS-FET handling precautions to avoid
electrostatic discharge.
NOTE: Wear required grounded wrist straps and observe proper ESD safety precautions when
handling the electrostatic-sensitive printed circuit boards.
Environmental statement - Bosch has a strong commitment towards the environment. This
unit has been designed to respect the environment as much as possible.
Fuse rating - For protection of the device, the branch circuit protection must be secured with
a maximum fuse rating of 16A. This must be in accordance with NEC800 (CEC Section 60) .
Grounding and polarization - This unit may be equipped with a polarized alternating current
line plug (a plug with one blade wider than the other blade). This safety feature allows the
plug to fit into the power outlet in only one way. If unable to insert the plug fully into the
outlet, contact a locally certified electrician to replace the obsolete outlet. Do not defeat the
safety purpose of the polarized plug.
Alternately, this unit may be equipped with a 3-pole grounding plug (a plug with a third pin for
earth grounding). This safety feature allows the plug to fit into a grounded power outlet only.
If unable to insert the plug into the outlet, contact a locally certified electrician to replace the
obsolete outlet. Do not defeat the safety purpose of the grounding plug.
Moving - Disconnect the power before moving the unit. Move the unit with care. Excessive
force or shock may damage the unit and the hard disk drives.
Outdoor signals - The installation for outdoor signals, especially regarding clearance from
power and lightning conductors and transient protection, must be in accordance with NEC725
and NEC800 (CEC Rule 16-224 and CEC Section 60) .
Permanently connected equipment - Incorporate a readily accessible disconnect device
external to the equipment.
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).
SELV - All the input/output ports are Safety Extra Low Voltage (SELV) circuits. SELV circuits
should only be connected to other SELV circuits.
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.
