CHECKING THE INSTALLATION ENVIRONMENT
This product is a top-notch security device that is equipped
with a high-capacity HDD and other key circuit boards.
Note that an excessive internal temperature of the product
may cause a system failure or a shortened product life (see
the right figure). Keep in mind the following instructions
before installing the product.
When mounting the product on a rack, comply with the following instructions.
1. Please ensure that the rack inside is not sealed.
2. Please ensure the air is circulated through the inlet/outlet as shown in the picture.
3. If you pile up the prudcts or other rack-mount devices as shown in figure 2, secure
room for ventilation or install a vent.
4. For natural air convection, place the inlet at the bottom of the rack and the outlet on
top.
5. It is strongly recommended that a fan motor is installed at the inlet and the outlet for
air circulation. (Please fit a filter at the inlet to screen dust or foreign substances.)
6. Please maintain the temperature inside the rack or surrounding areas between 0°C ~
40°C (32°F ~ 104°F) as shown in the figure 1.
Rack Mount Instructions - The following or similar rack-mount instructions are
included with the installation instructions :
A) 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.
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.
C) Mechanical Loading - Mounting of the equipment in the rack should be such that a hazardous
condition is not achieved due to uneven mechanical loading.

D) 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.
E) 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).
RACK INSTALLATION
Install the Bracket-Rack as shown in the figure, and then fasten
the screws on both sides.
` Fix the screws not to be loosened by vibrations.
Cautions when Installing in the Rack
To install multiple NVRs in the rack, make sure to separate the FOOT at the bottom of each NVR.
1. There are four FOOTs at the bottom of a NVR.
Press the projected parts at both-ends of each
“FOOT” and turn it counterclockwise.
2. “FOOT” is separated from the main body when it is
turned to the end of fastening groove.
