CLEANING INSTRUCTIONS

If dust accumulates on the NGC-30-CRM/-CRMS circuit board use
dried compressed air to remove the dust. Turn off all power to the
NGC-30 panel. Carefully disconnect all cables from a single NGC-
30-CRM/-CRMS card, making sure to label cables so that they can
be reconnected after board cleaning. Wear an anti-static wrist
strap connected to ground in order to avoid component damage.
Remove the CRM/CRMS circuit card from the card cage and place
on a clean lint-free surface.
Use dry compressed air from a can for cleaning circuit boards.
(Avoid factory compressed air since it may contain enough
moisture or oil to cause permanent damage.) Use short quick
blasts to remove dust build-up as necessary. After cleaning,
replace the CRM/CRMS in the same card cage position and
reconnect all cables. Remove only one card at a time for cleaning
to avoid any problems during re-installation.

NGC-30-CR INSTALLATION INSTRUCTIONS
Mounting of Card Rack
Use the mounting template (on page 7) to mount the rack on a
panel backplane. There are four holes (0,48 cm dia.) to secure it
to the mounting surface using #8 screws.
Once the card
rack is installed,
a earth bonding
wire must be
connected to the
card rack using
the ground screw
provided.
Note: The card
rack must be
installed on a
non-combustible
surface.
