c. CIRCUIT-CARD INSERTION AND REMOVAL
All of the new Daytronic “AA” Conditioner Cards are “hot-pluggable”—as are all
of the standard “10A” Conditioner Cards whose model number ends in
“C.” This
means that you need NOT turn off mainframe power before inserting or removing
the card.
FOR ALL OTHER CONDITIONER CARDS, HOWEVER, ALWAYS MAKE SURE
THAT MAINFR
AME POWER IS OFF BEFORE CHANGING THE POSITION OF
THE ACTUATING LEVER OF THE CARD’S SLOT.
For complete instructions on “Card Insertion and Removal,” see Section 1.B.
d. HANDLING CARDS WITH INTERNAL BATTERY
NEVER LAY DOWN A CIRCUIT BOARD CONTAINING A LITHIUM BATTERY ON
ANY METAL OR OTHER CONDUCTIVE SURFACE, UNLESS THE BOARD HAS
PROTECTIVE, VELCRO-ATTACHED MYLAR SHEETS (WHICH SHOULD NEVER BE
REMOVED). Short-circuiting of the battery could occur, with possible severe
damage to the instrument.
e. AIR COOLING REQUIREMENTS
ALL MAINFRAMES REQUIRE COOLING. The cooling air intake is at the bottom of
each unit. When rack-mounting a System 10 mainframe, you should provide at
least 1.75 inches of clearance below the unit, to ensure proper air flow. When the
mainframe is used as a bench-top instrument, the installed 0.5-inch rubber feet
will allow sufficient air flow.
ALSO, TO MAINTAIN PROPER AIR COOLING, THE MAINFRAME SHOULD NEVER
BE OPERATED FOR ANY LENGTH OF TIME WITH ITS FRONT BEZEL(S) OFF.
f. DUST COVERS
Be sure to keep a protective “T” insert in every unused SLOT CONNECTOR, to
prevent the accumulation of dust in the connector (see Section 1.B).
