Manual

CAUTION: The MPAX main circuit board and the option cards
contain static sensitive components. Before handling the module
or the cards, discharge static charges from your body by
touching a grounded bare metal object. Handle the module by
the rear plastic cover only, and the option cards by the board
edges. Dirt, oil or other contaminants that contact the circuit
boards or components can adversely affect circuit operation.
WARNING: Exposed line voltage exists on the MPAX main circuit
board and the option cards. DO NOT apply power to the
module OR load circuits until the module is properly installed
in the EPAX case.
NOTE: All module and option card labels must be installed as
shown for safety purposes.

Removing The MPAX Module
To remove the MPAX Module from the EPAX Display, first remove all
power and load circuits. Then insert a flat screwdriver blade (
3
/
16
"
or
1
/
4
") into the narrow slot between the EPAX rear cover plate
and the module’s plastic cover as illustrated in Figure 2.
Twist the screwdriver in the direction shown to
disengage the internal connectors while firmly
squeezing and pulling back on the rear
finger tabs (top and bottom).
Carefully slide the module out
of the EPAX case, keeping
it properly aligned
with the case
opening.
1.0 ASSEMBLING THE DISPLAY
Prior to installing the EPAX Display, it is recommended that
the MPAX and any option cards be assembled first. This will
allow you the opportunity to insure all the boards are fitted
properly into their connectors.
Installing the Option Cards
If your application requires option cards, they should be
installed into the MPAX before it is installed into the EPAX
Display. Refer to the literature enclosed with the option cards for
installation instruction.
Installing the MPAX
Remove the MPAX case (plastic) from the rear of the
EPAX by removing the two screws and pulling off the metal
holding bracket. Install the MPAX into plastic case by
aligning the front connector of the MPAX with the hole in
the front of the plastic case. The module must be oriented
as shown with terminal #1 toward the top of the EPAX
case. Next, insert the MPAX case into the EPAX by lightly
pushing the connector of the MPAX into the connector of
the EPAX PC board. Place holding bracket over the plastic
case and install the two screws.
Installing the Labels
Each option card and the MPAX are shipped with a connection
label. These labels must be applied to the rear of the EPAX in the
positions shown in the drawing.
