Arrival of Equipment
Receiving
Upon arrival of the equipment, inspect it for damage. Promptly report all vis-
ible damage to the carrier. All shipping damage claims must be filed with the
carrier.
Storing
During storage in a warehouse or on the job site, precautions should be taken to
protect the equipment from dust, dirt, moisture, and temperature extremes.
Static Protection Guidelines
Read this page before working with electronic circuit boards.
Elevator systems use electronic circuit boards to control various functions of
the elevator. These boards have components that are extremely sensitive to
electrostatic voltage, which can cause board damage or failure.
Proper handling and shipping of boards is important to ensure their reliability
and long-term operation. For this reason, manufacturing bases warranty deci-
sions on the guidelines below.
Handling
• Store boards in separate, sealed, anti-static bags until time for installation.
• When handling boards, wear an anti-static wrist strap with ground wire.
Acceptable straps are available through local electronics parts suppliers.
Typical anti-static wrist straps are intended for applications below 240 VAC.
• Do not place boards on any surface without adequate static protection.
• Handle boards only by their edges using proper anti-static techniques.
Avoid touching components, traces, and connectors.
• Take extra care when handling individual components, such as integrated
chips, metal oxide semiconductors, and field-effect transistors. These com-
ponents can be destroyed with as little as 30 volts of electrostatic dis-
charge.
Shipping
• Complete the included board discrepancy sheet.
• Any board returned to manufacturing must be packaged in a closed,
sealed anti-static bag designed for the board, and packaged in a sturdy
protective shipping carton.
• Clear bubble wrap and Styrofoam are unacceptable packing materials.
Failure to adhere to the above guidelines will void the board warranty.
