Static Protection Guidelines
IMPORTANT!
Read this page before working with electronic circuit boards.
Elevator control systems use a number of electronic cards to control various functions of the
elevator. These cards have components that are extremely sensitive to static electricity and are
susceptible to damage by static discharge.
Immediate and long-term operation of an electronic-based system depends upon the proper
handling and shipping of its cards. For this reason, the factory bases warranty decisions on the
guidelines below.
Handling
•
Cards shipped from the factory in separate static bags must remain in the bags until time for
installation.
•
Anti-static protection devices, such as wrist straps with ground wire, are required when
handling circuit boards.
•
Cards must not be placed on any surface without adequate static protection.
•
Only handle circuit cards by their edges, and only after discharging personal static electricity to
a grounding source. DO NOT touch the components or traces on the circuit card.
•
Extra care must be taken when handling individual, discrete components such as EPROMS
(which do not have circuit card traces and components for suppression).
Shipping
•
Complete the included board discrepancy sheet.
•
Any card returned to the factory must be packaged in a static bag designed for the card.
•
Any card returned to the factory must be packaged in a shipping carton designed for the card.
•
“Peanuts” and styrofoam are unacceptable packing materials.
Note:
Refer to the
Vertical Express Replacement Parts Catalog
to order extra static bags and
shipping cartons for each card.
Failure to adhere to the above guidelines will VOID the card warranty!
