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 (

" or

") 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.
