6.3 Tubing Connections
Connect the sample LFE inlet in Fig. 4 to the aerosol source or other inlet using the black
conductive tubing supplied.

6.4 Electrical Connections

When connecting the ribbon cable in Fig. 4 be very careful that it is inserted perpendic-
ular to the mating brown connector on the circuit board. Be sure to connect the provided
display ribbon cable to the main board before applying power if the instrument will be
configured using the user interface via the display.
Warning: Be sure the blue or black colored side at the ends of the rib-
bon cable is against the darker brown connector clamping piece on the
mating connector. Do NOT connect or disconnect the ribbon cable while
power is applied.
NOTE: except for the Model 9404 mSEMS, the front panel display for the
mini-OPC is NOT compatible with other 9400 series ACCESS instruments.
It employs a wider, 12 conductor cable instead of the 10 conductor cable
used on other devices.
Connect the AC-DC power supply from the ship kit to the power input connector on the
two-pin connector shown in Fig. 4. To facilitate the use of a battery to power the mini-
OPC, DC voltages between 9 and 16 Volts may be used and should be connected to the
Molex power in connector provided with the unit. Any AC adapter with an output of 9-
16 Volts DC at 1 AMP can be used to power the mini-OPC. The instrument firmware au-
tomatically runs when power is connected. Ensure the power plug is fully seated in the
connector before connecting the instrument to a computer.
