Operating considerations
 Power supply
Check that the supplied voltage is between 10.5
and 15 VDC. Inadequate voltage can affect
color fidelity and cause noise, while voltage over
15 V can damage the camera.
 Connectors
Confirm the power is off before connecting or
disconnecting a signal cable. Grasp connectors
by the body, not the attached wires.
 Lens
The correct lens is important for deriving
optimum performance from the camera.
Consult a Hitachi Denshi dealer for a selection of
fine lenses according to the application.
 Installation and storage sites
The following types of environment can impair
performance, lead to damage, pose safety hazards
and shorten the useful life of the camera. Select
the sites for installing the storing the camera
carefully.
• Direct sunlight, rain or snow
• Flammable or corrosive gasses
• Very hot or cold (beyond -10 to 45 ℃
operating, -20 to 60 ℃ storage)
• Humid or dusty
• Exposed to vibration or shock
• Strong electrical or magnetic fields
• Exceptionally strong light
Continuous operation
In situations where the camera is used
continuously for long periods of time, the
ambient temperature should be kept below 40 ℃
in order to avoid accelerated deterioration of
internal parts and to derive maximum long-term
reliability.
