1.3 Safety Precautions
To ensure the most effective and extended use of all equipment, adhere to the following precautions:
Wiring
• Use only the specified cables for all system connections.
• Do not use a high voltage circuit as a frame ground (FG). Also, the frame ground should be
separate from the power ground. The use of a grounding rod located as close as possible to
the enclosure housing the AFC1500 Multi-2 Unit is preferable.
• Circuit breakers or fuses are required on branch circuit power feeds to the Multi-2 Unit.
• PLC I/O cables must be run separate from any high voltage sources or cabling, and must not
exceed 50 feet.
Installation Environment
• The AFC1500 Multi-2 Unit should be placed in a NEMA 12 enclosure.
• Using the equipment in the following locations may lead to malfunction or breakdown. Avoid
using in these areas or use an air conditioner.
Areas under direct sunlight or if the environmental temperature is out of the 32~122
¡ 0~50
¢
) range.
Areas where relative humidity is out of the 20-90% range, the temperature change is
drastic or where the area is exposed to mist and water drops.
• Do not use at the following locations. (Contact FEC Inc. if necessary for clarification)
Areas where conductive powder, oil, mist, salt or organic solvents exist.
Areas that have corrosive or combustible gases.
Areas that have strong electric or magnetic fields.
Areas where strong vibration or shock could be transmitted directly to a Multi 2 Unit.
Static Electricity
• The AFC1500 Multi-2 Unit incorporates many electronic Surface Mounted Devices (SMD). It
is advisable to strictly adhere to practices for safe electrostatic discharge in order to prevent
damage to the system components when handling them.
Cleaning
• Do not use any organic solvents, such as thinner, to clean a Multi-2 Unit. The solvent could
melt the surface paint, or penetrate inside and cause damage. A cloth dampened with alcohol
or warm water should be used to lightly wipe the components.
Electrical Noise Prevention
• Multi-2 Units must be located a minimum of 600mm from high transient voltage sources such
as transformers, motor starters, AC inverters and AC contactors. If it cannot be avoided, the
unit must be shielded.
• If high powered devices are used inside the enclosure, they must use a surge suppression
device.
• Make sure that the power supply lines and cables for connecting the unit and tool are not run
together inside the same duct.
Handling and Shipping
• It is critical that AFC1500 System components are properly handled and shipped in order to
maintain the system’s integrity. Adhere to the following requirements for shipping and
handling:
Loose AFC1500 Multi-2 Units must be individually packaged and shipped in anti-static
containers or wrap to prevent damage from electrostatic discharge.
If the Multi Unit is to be shipped in an enclosure, tighten all mounting screws to prevent
the unit from being dislodged.
Do not ship or store the unit in environments where the temperature is out of the
23~131 (-5~55
¢
) range or where the humidity is above 90%.
