Precautions Before Use - Panasonic MICRO-IMAGECHECKER PV310 Use Manual

Precautions before Use

Installation Environment
Avoid installing and operating the PV310 in the following locations:
•
Location with direct sunlight or environmental temperatures that exceed a range of the "operating ambient
temperature" for each product.
•
Locations with a relative humidity exceeding a range of the "operating ambient humidity" for each product
or with a condensing due to a sharp temperature change.
•
Locations with an atmosphere containing corrosive gases or flammable gases.
•
Locations subject the main unit to direct vibration or impact.
•
Locations with a lot of fine particles, iron filings or salt.
•
Locations where the product can become wet with water, oil or chemicals.
•
Locations with an atmosphere likely to contain organic solvents (such as benzene, paint thinner, and
alcohol) or strongly alkaline materials (such as ammonia and caustic soda).
•
Locations where a load applies onto the unit.
•
Locations near the devices that generate large switching surges, high-voltage wires and devices,
power-driven lines and devices, and transmitting devices, such as radios.
Static Electricity
•
In dry environment, high voltages of static electricity might be generated. When you touch the product, you
should always discharge the accumulated static electricity through your body by touching a grounded
metal surface.
Cleaning
•
Never use thinners or similar solvents, as they may dissolve the board and lead to colors to run.
Power Supply Unit and Power Sequence
•
Use an insulated power supply with a built-in protection circuit. Applying an abnormal voltage might
damage the internal circuit. If you use a power supply unit without a protection circuit, supply power
through a protective device such as a fuse.
•
Consider the power supply sequence so that the power supply unit for the PV310 can be turned off before
the one for the input/output is turned off.
•
If you turn the input/output power off before turning off PV310, the device will detect a change in the input
signal level and may malfunction.
Before Turning on the PV310
•
Pay attentions to the followings when turning on the PV310 for the first time:
- Confirm no wiring waste or especially any conductive substance is on the printed circuit board.
- Confirm that the power wiring, input/output wiring and power supply voltage are correct.
- Confirm that the fixing and terminal screws are securely tightened.
