Model MLE-6
Enclosure for the MXL/MXLV Control Panel
INTRODUCTION
Model MLE-6 from Siemens Industry, Inc. is a
large-size enclosure for the MXL/MXLV System.
The enclosure consists of a backbox and front
door that is shipped assembled. Note that the
backbox has a flanged lip to permit semi-flush
mounting in addition to the usual surface
mounting.
Consider the following when mounting the
backbox:
• Mounting height for visual and manual
access to the MKB-2 Keyboard/annunciator
• Weight and size of enclosure
• Local mounting codes
Fasten the backbox securely to a clean, dry,
shock-free, and vibration-free surface. MLE-6
enclosure is for indoor use only in dry environ-
ments. Position the backbox clear of obstruc-
tions so that the front door opens freely and so
that the indicators and controls are easily
accessible.
NOTE: When the backbox is mounted semi-
flush, be sure that the position of the
backbox permits the front door to
swing fully open.
To install the MLE-6 backbox:
(Refer to Figure 1.)
1. Slip the front door off the hinges of the box
and put it to one side temporarily.
2. Remove the knockouts in the backbox
where field wiring is required.
