Removing The Rear Covers: EMC 6/4, 6/4M, 6/4MT, EMC 10/4, EMC 10/4T
The rear covers are attached to the peripheral frame with plastic tabs in
the front of the covers and with machine screws on the backside of the covers.
All covers are removed and reinstalled in the same manner, however, they
must follow a specific sequence since some of the covers overlap others.
Rear cover #4 covers the Controller Section which houses the EMI
(Electro-Magnetic Interference) box and its printed circuit boards. As with
other covers, it is attached with screws at the rear and tabs on the front.
Cover #4 overlaps covers #3 and #5, and is the first of the 5 covers to be
removed and becomes the last cover installed.
After removing cover #4 you will remove cover #5, which covers the Z motor
and encoder area; then remove covers #3, #2, and then #1 in that order in the
other direction. (Refer to the figure below for an illustration of the covers
and their removal/installation sequence.

Use a small brush or can of compressed air to clean any dust or accumulated
lint from inside the caps themselves, as well as the electronic components.
