1.1 Important Safeguards and Warnings
Electrical safety
•
Install the unit in accordance with the manufacturer’s instructions and in accordance with
applicable local codes.
•
All installation and operation must conform to your local electrical safety codes.
•
Do not overload outlets and extension cords, which may cause fire or electrical shock.
•
Do not place the camera near or in a place where the camera may contact overhead power lines,
power circuits, or electrical lights.
•
Ensure power conforms to SELV (Safety Extra Low Voltage) and that the limited power source is
rated AC 24V as specified in IEC60950-1. (Power supply requirement is subject to the device
label).
•
All input/output ports are SELV circuits. Ensure that SELV circuits are connected only to other
SELV circuits.
•
Ground the unit using the ground connection of the power supply to protect the unit from damage,
especially in damp environments.
•
Protect the plug and power cord from foot traffic, being pinched, and its exit from the unit.
•
Units with or without an ON/OFF switch have power supplied to the unit whenever the power
cord is inserted into the power source; however, the unit is operational only when the ON/OFF
switch is in the ON position. The power cord is the main power disconnect device for switching
off the voltage for all units.
•
Operate the unit only from the type of power source indicated on the label. Before proceeding,
disconnect the power from the cable to be installed into the unit.
•
For external power supplied units, use only the recommended or approved power supplies.
•
Limited power sources must comply with EN 60950. Substitutions may damage the unit or
cause fire or shock.
•
For 24 VAC units, voltage applied to the unit’s input power should not exceed ±25%. User-
supplied wiring must comply with local codes (Class 2 power levels). Do not ground the
supply at the terminals or at the unit’s power supply terminal.
•
Contact the local dealer or the power company to verify the correct power supply.
•
Do not supply power via the Ethernet connection (PoE) when power is already supplied via the
power connector.
•
Do not attempt to service the unit. Opening or removing covers may expose you to dangerous
voltage or other hazards. Refer all servicing to qualified personnel.
