Be careful not to use cables that seem worn or old.
•
Never, under any circumstances, make any changes or connections that are not shown in this
handbook. Improper use of the appliance can cause serious hazards, risking the safety of personnel
and of the installation.
•
Use only original spare parts. Non-original spare parts could cause fire, electrical discharge or other
hazards.
•
Before proceeding with installation, check the supplied material to make sure it corresponds to the order
specification by examining the identification labels.
•
This device was designed to be permanently secured and connected on a building or on a suitable
structure. The device must be permanently secured and connected before any operation.
•
The product is designed to house only cameras that are properly certified.
•
A power disconnect device must be included in the electrical installation, and it must be very quickly
recognizable and operated if needed.
•
The separate protective earthing terminal provided on this product shall be permanently connected to
earth.
•
Installation category (also called Overvoltage Category) specifies the level of mains voltage surges that
the equipment will be subjected to. The category depends upon the location of the equipment, and on
any surge voltage protection provided. Equipment in an industrial environment, directly connected to
major feeders/short branch circuits, is subjected to Installation Category III. If this is the case, a
reduction to Installation Category II is required. This can be achieved by use of an insulating transformer
with an earthed screen between primary and secondary windings, or by fitting UL listed Surge
Protective Devices (SPDs) from live to neutral and from neutral to earth. Listed SPDs shall be designed
for repeated limiting of transient voltage surges and the following rated operation conditions: Type 2
(SPDs permanently connected to the power network and intended for installation on the load side of the
service equipment); Nominal Discharge Current (In) 20 kA min.
For example: FERRAZ SHAWMUT, STT2240SPG-CN, STT2BL240SPG-CN rated
120 Vac / 240 Vac, (In=20 kA). Maximum distance between installation and reduction is 5 m (16.4 ft).
•
The device must be properly connected to the earth circuit.
•
Equipment intended for installation in Restricted Access Location performed by specialist technical staff.
•
Connect the device to a power source corresponding to the specification given in this document.
