Chapter 2 - Installation of Monitor
This monitor is intended to be mounted in and used where NEMA 4 and NEMA 12 type
enclosures are employed. Enclosures made of heavier gauge metal work better because they won’t
deform or bend as easily when the monitor’s sealing gasket is compressed. The monitor meets NEMA
4/12 sealing specifications when properly installed in an approved NEMA enclosure constructed from 14gauge or heavier steel. The monitor uses “U”-shaped clips and a special gasket to achieve the proper
seal.
When selecting an enclosure remember to allow adequate space around the rear of the monitor
for good air flow. Do not block air flow from below or above the monitor. If possible mount the monitor in a
vertical orientation. The monitor is designed to work in environments up to 50 degrees Centigrade.
Remember to account for heat dissipated from other equipment that may be inside the same enclosure.
To install the monitor, make a cutout according to the diagram below in one of the walls of your
NEMA enclosure. Next hold the monitor in place while you install the mounting clips. Tighten the clips
to the point were the back of the monitor’s front bezel just begins to contact the front of the NEMA
enclosure. The use of an adjustable torque driver is recommended. The screws should be tightened to 8
inch-pounds. Tighten the clips in a cross pattern. This will help to develop an even pressure on the
sealing gasket. DO NOT OVER TIGHTEN AS DAMAGE CAN RESULT IN THE MONITOR CAUSING
LOSS OF SEALING INTEGRITY.

Connecting Power
The VISIO15 monitor is powered from 100-240 VAC, 50/60 Hz or optionally from 24 VDC.
Damage will occur if 100-240 VAC power is connected to an VISIO15 equipped with the 24 VDC
input power option. VISIO15’s equipped with the 24 VDC option will have a “-24” suffix in their model
number such as VISIO15-24 or VISIO15T-24.
Because the VISIO15 is UL 1604 listed for Hazardous Location use, (Class I Division2, Groups A,
B, C, D; Class II Division 2 Groups F and G: Temperature Code T4A), it has no power switch for switching
off supplied power. Please read the functional description of the POWER button on page 12.
Consideration should be give to the installation of an appropriately rated external power switch if the
application requires powering off the VISIO15.
Power is connected to the VISIO15 through a removable Phoenix Contact plug (Phoenix Contact
P.N. 1777992) that allows for screw termination of field wiring. The use of 18 AWG or greater (12 AWG
maximum) is recommended. Connect the field wiring according to the appropriate table below. After the
connections are made, make sure the plug retention screws (the two screws shown in the “Front View”
below) are securely tightened. This will prevent the plug from pulling out.

Connection of VGA and Touch Screen Cables
Connect the VGA cable and either the RS-232 or USB cable if the monitor is equipped with a
touch screen. All communication cables should include a chassis ground shield. Hazardous location,
Division 2, requires that all cables have adequate strain relief. For this reason, tighten all connector thumb
screws securely. If a USB cable is being used, install the provided USB retention bracket. Insert the USB
connector through the square cutout in the base of the bracket and pull the cable and body of the
connector back through the round hole in the bracket flange. Now insert the bracket into the two slots on
the rear of the monitor and side it forward so the connector is fully inserted in the mating bulkhead
connector. Install and tighten two 4-40 x .25” Philips screws.

Turning on the Computer and Monitor
With power applied to the monitor and all cables connected you may power up the computer and
press the POWER button on the rear of the monitor. The POWER LED will switch from off to green. The
monitor will perform an automatic self configuration and begin displaying an image. If the computer is
subsequently powered off, the monitor will remain on and display the NO SIGNAL error message (page
22) indefinitely. The POWER LED remains green. The touch screen remains active during this time.
When the computer is powered on again, the NO SIGNAL message disappears and normal image
display resumes.
Selection of PC Video Settings
Although the VISIO15 can display several different video modes, the optimum display image
performance occurs when the PC’s video settings match the native resolution of the VISIO15’s LCD. For
this reason it is recommended that you set the video mode to 1024 x 768 with a screen refresh rate of 60
Hz.
This can be done using Window’s control panel or by right clicking on the desktop and choosing
“Properties”. This will bring up the “Display Properties” menu. From this menu, select the “Setting” tab and
choose 1024 x 768 for the Screen resolution. From the Settings menu, choose “Advanced” and then click
on the “Monitor” tab to set the Screen refresh rate to 60 Hz.

The following OSD message will appear if the horizontal or vertical refresh rate of the incoming
video signal is outside the range of the monitor.
NO SIGNAL
When the monitor is first turned on it performs a set of self diagnostics. If no incoming video
signal is detected immediately following self diagnostics, the following message will appear. This
message will remain indefinitely until a valid signal is detected. The LED remains green.
POWER SAVER MODE
The following message appears when the monitor is on but in DPMS (Display Power
Management Signaling) mode. This occurs after a valid incoming video signal is no longer preset or when
