REPLACING THE GATEWAY (A-B20-750-20COMM OPTION CARD) — The following are the steps for remov- ing and replacing the existing gateway.

1.Disconnect power to the drive. Before removing the en- closure, open the access door on the front of the drive. See Fig. 16.

2.Check to be sure that the voltage between DC+ and DC- and from each DC terminal to the chassis is zero before proceeding. See Fig. 17.

3.Remove the enclosure. See Fig. 18.

4.Remove the 2 screws securing the mounting plate and re- move the mounting plate and COMM card. See Fig. 21.

5.Mount the new COMM card and mounting plate and at- tach with the 2 screws removed in Step 4. See Fig. 22.

6.Use the shorter ribbon cable to connect the plug on the COMM card to the connector on the mounting plate. See Fig. 21.

7.Install the enclosure. See Fig. 18.
