(08/04) GEM80-500 Technical Manual (T2025En) Page 6-3
an Optional Panel Mounting Kit type 8890-4900 available from ALSTOM. Each
method of mounting is now described. Whichever method of mounting is used ensure
that:
(a) The selected mounting position will have a gap above and below the controller of
at least 50 mm for the free flow convection cooling air.
(b) The selected mounting position provides sufficient space at the front of the
controller for cabling access and viewing of the controller status LEDs.
6.6 Panel Mounting the Controller
6.6.1 Direct Mounting (without using a Panel Mounting Kit)
The GEM80-500 Controller has four M5 size tapped inserts in its rear face that allow it
to be panel mounted. This method of mounting is suitable for locations where access
is available to the front and rear of the panel on which the controller is to be mounted.
Figure 6-1 shows the fixing hole dimensions for this type of mounting.
The controller is mounted with four M5 screws (of maximum length 10 mm) through
the panel, from the rear, into the tapped inserts in the controller rear face.
6.6.2 Using a 8890-4900 Panel Mounting Kit
If access can only be gained to the front face of the panel on which the controller is to
be mounted, then use of an Optional Panel Mounting Kit 8890-4900 is recommended.
This kit consists of a metal Mounting Panel, four M5 x 10 mm screws and spring
washers, and four M5 Taptite screws. The Mounting Panel includes four keyhole slots
for fixing the Mounting Panel, with controller attached, in its preferred position.
Refer to Figure 6-2 and use the Mounting Kit 8890-4900 as follows:
(a) Drill the panel as shown at Figure 6-2 and fit the four M5 Taptite screws to
approximately half their thread depth.
(b) Fix the metal Mounting Panel to the rear face of the controller with the four M5 x
10 mm size screws and spring washers. The screws fit into tapped inserts on the
rear face of the controller.
Note:
Ensure that the keyhole slots are in the correct vertical orientation.
(c) Locate the keyhole slots in the Mounting Panel over the heads of the four M5
Taptite screws. Now fully tighten the four Taptite screws.
