Esd Handling Precautions - Honeywell CNI2 Operating And Installation Manual

ESD HANDLING PRECAUTIONS

Any electronics device contains components sensitive to ESD (electrostatic discharge). For
example people experience up to 35kV ESD, typically while walking on a carpet in low humidity
environments. In the same manner many electronic components can be damaged by less than
1000 volts of ESD. For this reason you must observe the following handling precautions when
servicing this equipment:
1) Always wear a conductive wrist strap.
2) Eliminate static generators (plastics, Styrofoam, and so on) in the work area.
3) Remove nylon or polyester jackets, roll up long sleeves, and remove or tie back loose
hanging neckties, jewelry, and long hair.
4) Store and transport all static sensitive components in ESD protective containers.
5) Disconnect all power from the unit before ESD sensitive components are removed or
inserted, unless noted.
6) Use a static safeguarded workstation, which can be set up by using an anti-static kit
(Motorola part number 0180386A82). This kit includes a writes strap, two ground cords,
a static control tablemat, and a static control floor mat. The Motorola part number for a
replacement wrist strap that connects to the tablemat is 4280385A59.
7) When anti-static facilities are unavailable, use the following technique to minimize the
chance of damaging the equipment:
8) Let the static sensitive component rest on a conductive surface when you are not
holding it.
9) When setting down or picking up the static sensitive component, make skin contact with
a conductive work surface first and maintain this contact while handling the component.
10) If possible, maintain relative humidity of 70-75% in development labs and service shops.
Less humidity is more conducive towards static charge buildup and subsequent
discharge.
