Removing the MCA Assembly for Service

NOTE!

Refer to

as this procedure is performed.

1.

These steps require wearing a grounding strap as previously described.

2.

Remove the following cables from the MCA Interface Option circuit card (if installed).

a)

Various MCA Interface Options are available, remove any cable(s) connected to the circuit card.

3.

Remove the following cables from the Rectifier Shelf Interface circuit card.

a)

Separate the cable connected to the pigtail cable permanently connected to the circuit card.

b)

Disconnect the cable from connector J2.

c)

Disconnect the cable from connector J4.

4.

Remove the following cables from the MCA Main Controller circuit card.

a)

Disconnect the cable from connector J8.

b)

Disconnect the cable from connector J9. To do so, grasp the ejector tabs at each end of the
connector and pivot outward, forcing the plug out of the connector.

c)

If a Battery Ambient Temperature Probe or TXM is installed, remove the connector from J4.

5.

Using a 5/16” nut driver, remove the two hex nuts and ground washers that secure the MCA assembly to
the floor of the Distribution Cabinet.

6.

Lift the front of the MCA assembly and pull straight out of the Distribution Cabinet. Remove the MCA
Assembly to a static-safe work surface.

MCA Power Supply Circuit Card Assembly Replacement Procedure

NOTE!

Refer to

and

as this procedure is performed.

1.

Remove the MCA assembly to a static-safe work surface as describe in the

“

Removing

the MCA

Assembly for Service”

procedure.

WARNING!

Damage to the MCA may result if the next step is not followed.

2.

Connect an approved grounding strap to your wrist. Attach the other end to a suitable ground.

3.

Locate the metal bracket that is under the Rectifier Shelf Interface circuit card. Loosen but do not
remove the four Phillips screws that secure the metal bracket. Remove the metal bracket with the
Rectifier Shelf Interface circuit card by sliding toward the rear of the MCA assembly until the screw
heads clear the slots in the bracket. Lift the bracket and circuit card from the MCA assembly, and set
aside.

4.

Remove the ribbon cable permanently connected to the MCA Power Supply circuit card from connector
J2 on the rear edge of the MCA Main Controller circuit card.
