DANGER
To reduce the risks associated with fire and explosion which, if not
avoided, will cause death or serious injury and/or property damage:
Do not open the ET unit (or hatch, if applicable) while the circuit is live
unless the area is known to be non-hazardous.
Do not use an external keyboard or mouse unless the area is known to be
non-hazardous.
Do not operate the ET unit’s OSD switches, DIP switch, KVM extender
remote board, or potentiometer on the KVM extender remote board unless
the area is known to be non-hazardous.
Do not disconnect equipment unless power has been switched off or the
area is known to be non-hazardous.
Do not replace the fuse unless the power has been disconnected and the
area is known to be non-hazardous.
Do not use the ET unit in Class I, Division 1; Zone 0; or Zone 1 hazardous
locations.
WARNING
To reduce the risks associated with electrical shock, fire, or
explosion which, if not avoided, could result in death or serious
injury and/or property damage:
Follow all product and accessory installation instructions, including
instructions for mounting the unit with a NEMA 4X panel gasket (ships with
all ET 355 monitors) and instructions that accompany the NEMA 4X hatch
kit.
The procedures described in this document should be performed only by
trained personnel. Failure to perform all operations correctly could
damage the unit and invalidate the warranty.
For servicing or other procedures not described in this document, in the
ET 350 Monitor User’s Installation Guide, or in other ET 35X instructions,
return the ET unit to 3M Touch Systems for servicing.
Read and understand all safety information before installing and using the
ET unit.
Engineer the installation of the ET unit to take into account the operating
environment (e.g., hazardous location, shock/vibration factors).
Properly install the ET unit with a NEMA 4X gasket that is clean,
undamaged, and effective.
Do not modify the ET unit.
Do not substitute components. Substitution of components may impair
suitability for a Class I, Division 2; Class II, Division 2; or Zone 2 hazardous
location.
When replacing a fuse or other part, use a part of the type and rating
specified by 3M Touch Systems.
Provide a clean, reliable ground.
Use locking devices on connectors.
To ensure compliance with electrical codes and safe operation of the
monitor, have a licensed journeyman electrician familiar with local codes
perform all wiring and installation tasks.
When connecting power with fixed field wiring in the NEMA 4X hatch, the
field wiring must be double insulated. A clear, flexible insulator (supplied)
must cover the portion of the cable that is not double insulated when
connecting to a terminal strip connector.
After making an opening in the NEMA 4X hatch, make sure that there are
no metal shavings in the hatch.
When installing the ET unit, ensure that specifications for supply circuit
overcurrent protection and wiring are not exceeded.
Choose listed (UL) conduit hub or Notified Body Certified gland rated
NEMA 4X/IP66 that is suitable for use in hazardous locations, and provide
adequate strain relief for wiring.
Properly install the ET unit so that it is environmentally sealed to the
NEMA 4X/IP66 standard. Do not use the ET unit with mounting options
that are not rated for NEMA 4X/IP66 in environments that require such a
seal. Use the NEMA 4X hatch with ET 35X monitors with heater.
If a KVM extender is used with the ET unit, the KVM local unit should be
located in an area known to be non-hazardous.
Do not use flammable or combustible cleaners on or near the ET unit.
WARNING
To reduce the risks associated with electrical shock or fire which, if
not avoided, could result in death or serious injury and/or property
damage:
If the ET unit is mounted using a NEMA 4X panel gasket, install the unit in
a Listed (UL) enclosure.
If the ET unit will be used in corrosive environments, it is the responsibility
of the user to test and evaluate the unit in those environments. The
monitor, as shipped, has not been evaluated for use in excessively
corrosive environments. Using it in such environments, without evaluation
and testing, may lead to unsafe conditions.
WARNING
To reduce the risks associated with electric shock and/or burn-
related injury that could result in death or serious injury and/or
property damage:
Avoid contact with connectors on power terminal strip unless the power
has been disconnected.
Avoid exposed electrical contacts inside the ET unit.
WARNING
To reduce the risks associated with electrical shock which, if not
avoided, could result in death or serious injury and/or property
damage:
Make sure that the ground potential difference between the ET unit and
the host computer is less than 2V.
Before removing the ET unit from its mounting or performing any other
service to the monitor, disconnect power to the unit.
Provide adequate strain relief for all field wiring in accordance with Class
I, Division 2 wiring methods Article 501-4(b) of the National Electric Code,
NFPA 70 for installations in the U.S., or as specified in Section 18-1J2 of
the Canadian Electrical Code for installations within Canada and in
accordance with the authority having jurisdiction.
WARNING
To reduce the risks associated with electrical shock or mechanical
function which, if not avoided, could result in death or serious injury
and/or property damage:
Apply a “safe touch” setting, especially if the ET unit is running an
application or is in a setting where safety is a concern.
Do not use a non-Windows operating system screen saver that may affect
the “safe touch” setting and could in turn cause connected peripheral
equipment to start or stop inadvertently.
Set the safe touch setting correctly, with the number of minutes entered
for the Windows operating system’s energy saver being at least one
minute greater than the time entered for the Windows operating system
screen saver.
If your ET unit has a display power management system (DPMS) that is
configurable from the display’s on-screen Utility menu, do not turn off the
DPMS.
WARNING
To reduce the risks associated with electric shock and/or burn-
related injury that could result in death or serious injury and/or
property damage:
Do not open the power supply in the ET unit. It contains hazardous
voltage/hazardous energy. The power supply has no user-serviceable
parts or adjustments inside.
WARNING
To reduce the risks associated with mechanical function which, if not
avoided, could result in property damage:
Do not operate the ET unit in conditions outside of the operational
specifications.
