Section 3: INSTALLATION
Installation Prints:
Drawings and information contained in this section and the appendix of the manual are applicable to most installations.
However in some special cases, Ransburg may supply custom installation drawings for your specific site. It is highly
recommended that if your installation differs significantly from the installation drawings supplied by Ransburg, you notify
your Ransburg representative to ensure that standard installation practices are not violated and to have your prints up-
dated to reflect the installation accurately for future reference.
Equipment Locations:
The GMS control panel must be located outside of the hazardous area. If in doubt, contact your Ransburg representa-
tive for clarification.
MOUNTING THE CONTROL UNIT
The GMS control panel has an optional mounting kit available 79527-00. This kit allows either top mounting or back
mounting, with either swing-away or fixed attachment. There are four convenient ways of mounting the enclosure assem-
bly using the included hardware. See the Appendix section for the different mounting configurations available.
C A U T I O N
When mounting the control unit to a wall or ceiling, the 79527-00 Mounting Kit
should be used. If mounting to a non-metallic wall or ceiling, the mounting screws
must be secured to the wall or ceiling studs. If mounting to a metal wall or ceiling
(such as a spray booth) the wall or ceiling must be at least 0.050” (1.2mm) thick. In
both cases, the customer must supply the screws to attach the brackets to the wall
or ceiling. These screws should be at least 1/4” (6mm) in diameter.
I/O CONNECTIONS
For maximum noise immunity, I/O wiring should be run in conduit or cables having a foil shield with an overall braided
shield. The foil shield provides 100% shielding, while the braid provides a means of making proper 360° shield termina-
tions at the cable to cabinet connection points. To make I/O connections using shielded cable, perform the following:
1. Remove the cable grommet hardware from the I/O connector housing.
2. Route the desired length of I/O cable through the connector housing and mark 1” span of cable that passes
through connector housing to be stripped to braid.
3. Remove cable and strip marked 1” section to cable braid.
4. Slide the cable grommet hardware onto the cable.
5. Route the cable back through the connector housing and connect its wires to the desired I/O terminals inside
the GMS Control Unit or power supply.
6. Tighten the cable grommet ensuring the grommet spring makes 360° contact with the exposed braid of the
cable, for maximum noise immunity.
7. For maximum noise immunity, connect the braid of the cable to earth ground at the end opposite the control
unit or power supply.
