Maintenance
Cleaning Cards
Cards should be removed from the system and cleaned once a year (more
often in installations where conductive dust is present). The cards must be
removed and cleaned in an antistatic work area, using an antistatic mat on
the work surface and an antistatic wrist strap. Clean cards with an air hose
or vacuum cleaner that is static protected.

To remove dust from cards:
1. Use an air hose to blow the dust off the cards and assemblies.
Use very dry air or an ionizing nozzle on the air hose to prevent
static damage to the cards. Air pressure should be limited to 2.1
Kg/cm
2
(30 PSI).
or
2. Use a vacuum cleaner. We recommend use of a dust attachment
with a wire wrapped around the brush bristles, connecting to
ground throug ha1megohm resistor to eliminate static buildup on
the brush.

To clean edge connectors:
CAUTION
Do not use a rubber eraser to clean edge connectors. A
rubber eraser wears away the thin gold coating on the
connector and will then allow the contacts to corrode.
1. Use a “RUSH BRUSH” or similarly designed edge connector
brush to remove oxidation and contaminants from the gold coated
edge connectors.
2. To remove contaminants, wipe connector contacts with a s oft
tissue w etted with denatured alcohol.
Storing Cards
Cards must be stored in a clean area, free of corrosives. Always store
cards in an approved antistatic bag.
