Local rail module installation

Please refer to the installation sheet that came with the product for installation instructions.

Equipment locations within a chassis are referred to as rail slots.

Figure 5-7 indicates the rail slot numbers for the various cabinet sizes available in the EST3 product line. The CPU module must always occupy rail slots 1 and 2. The primary power supply monitor module should occupy rail slot 3.

Figure 5-7: Local rail module slot identification

A 3-ASU Audio Source Unit occupies the first three slots on its chassis, and is identified using the lowest slot number of the three. When a Firefighters Telephone Control Unit is supplied as part of the 3-ASU/FT, the telephone control unit occupies the last four slots on the chassis, and is identified as the fourth slot number (11 or 18) on the chassis.

Connect the DC power cable (P/N 250187) to connector P2 on the power supply. For the 3-PPS Primary Power Supply, connect the 16-pin data ribbon cable (P/N 250188); (Booster = P/N

250189) to connector P3 on the power supply. For 3-BPS

Installation

Booster Power Supplies, connect a 14-pin data ribbon cable (P/N

250189) to connector P3 on the power supply. Route both cables up through the rails for later connection to the power supply/booster monitor module.

• Install any local rail module option cards required by your application. Option cards should be firmly seated in their connectors, and then secured to the rail module by pressing the snap rivet fastener.

• If a control/display module is required by your application, place the display in the recess on the front of the module.

Secure the display with the four supplied plastic rivets.

Install the display ribbon cable (P/N 250186) between the display’s connector and the module’s display connector. If no display is required, insert the blank plate supplied with the module.

• Locate the required rail slot positions on the rail chassis.

Remember, the module location must match the location entered in the System Definition Utility program.

• Position the module so that any option card(s) rests in the card guides slot. Push the module toward the rails, sliding the daughter card into the slot.

• When the four alignment pins match up with the guide holes in the module, push the module in to firmly seat the module on the rail connectors.

• Push in the snap rivets to lock the module on to the rail.

• Plug in terminal strips can be removed from LRMs to facilitate field wiring.

• Close the module display door. Latch the door by sliding the upper latch down and the lower latch up.

Note:

If there are empty rail spaces in a cabinet, you should consider installing 3-LRMF blank modules to fill up the spaces.
