Installation
Prevent Electrostatic Discharge
Mounting of Master Module
Protective Enclosure A suitable enclosure should be
used to protect the Master Module from atmospheric
contaminants such as oil, moisture, dust, and
corrosive vapors or other harmful airborne
substances; if not, a reduced service life can be
expected.
The enclosure should be mounted in a position that
allows the access doors to open fully. This will
provide easy access to the wiring of the Master
Module and related components. A suggested
method for spacing and wiring layout for the Master
Module is shown in Appendix B. Also, see Appendix
B for drilling template.
Installation and Orientation Normal installation
and orientation of the Master Module within its
protective enclosure is defined in Figure B.1,
Appendix B. This orientation will ensure adequate
free convection cooling of the Master Module’s
internal electronic components.
Important: Do not block ventilation holes of the
Master Module. All wiring and other
obstructions
The mounting hole pattern for the Master Module is
defined by the dimensional drawing in Figure B.2,
Appendix B. The Master Module can be mounted
with either four No. 10 or M5 bolts or screws with
flat washers and an internal lock washer or
equivalent.
Mounting of Display Module
Protective Enclosure A suitable enclosure should be
used to protect the rear surfaces of the Display
Module from atmospheric contaminants such as oil,
moisture, dust and corrosive vapors plus other
harmful airborne substances. The Display Module’s
gasketed front panel interface to the protective
enclosure is rated as an IP65 degree of protection
[National Electrical Manufacturer’s Association
(NEMA)/Underwriters Laboratories (UL) 508, Type
4X (Indoor)] per International Standard IEC 529.
Installation and Orientation The Display Module
can be oriented in any position. The most typical
orientation is shown in Figure B.1, Appendix B. The
Display Module is designed to fit into the protective
enclosure cutout with a minimum installation depth
of 50.8 mm (2.0 in.) behind the mounting panel as
shown in Figure B.2, Appendix B. The recommended
Display Module mounting hole pattern and
dimensions are defined in Figure B.3, Appendix B.
Ensure that the gasket provided is not contaminated
with foreign matter and is installed in the Display
Module correctly. Install the Display Module into the
protective enclosure’s front panel using four M4 nut/
lockwasher assemblies as shown in Figure B.4,
Appendix B. Tighten the M4 nut/lockwasher
assemblies to 0.9 to 1.1 Nm (8 to 10 lb-in.)
Note: Eight flat washers are provided for retrofit
applications with larger hole sizes.

ATTENTION: Electrostatic
discharge can damage integrated
circuits or semiconductors if you touch
backplane connector pins. Follow these
guidelines when you handle the
module.
•
Touch a grounded object to discharge static
potential.
•
Wear an approved wrist-strap grounding
device.
•
Do not touch the backplane connector or
connector pins.
•
Do not touch circuit components inside the
module.
•
If available, use a static-safe work station.
•
When not in use, keep the module in its
static-shield box.
