information are at the end of this document (starting on
page 8). Definitions of safety symbols that are used on the

Intended Use
The ET 355 Monitor HL (hereafter, ET 355 monitor) is
intended to provide touch screen functions for industrial
applications in hazardous locations when the monitor is
connected to a host computer.
The ET 355 monitor is suitable for use in non-hazardous
locations and also in the following types of hazardous
locations. Using the monitor in locations other than these
will invalidate the warranty and will be solely the user’s
risk and responsibility:
Class I, Division 2, Groups A, B, C, and D hazardous locations;
temperature code T6 (less than or equal to 85°C).
Where:
volatile flammable liquids or flammable gases or vapors
exist, but are normally confined within closed containers;
ignitable concentrations of gases, vapors or liquids are
normally prevented by positive mechanical ventilation;
adjacent to a Class I, Division 1 location, where ignitable
concentrations might be occasionally communicated.
Class II, Division 2, Groups F and G hazardous locations;
temperature code T6 (less than or equal to 85°C)
. Where:
combustible dust is not normally in the air in ignitable
concentrations;
dust accumulations are normally insufficient to interfere
with normal operation of electrical equipment;
dust may be in suspension in the air as the result of
infrequent malfunctioning of equipment; or
dust accumulation may be sufficient to interfere with safe
dissipation of heat or may be ignitable by abnormal
operation.
Wiring methods must be 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.
Accessory connections must be evaluated in the end
application (i.e. nonincendive circuits).
Important
If there appears to be a conflict between information in the ET
350 Monitor User’s Installation Guide and this Installation
Addendum: ET 355 Industrial Monitor HL (for hazardous
locations), this addendum takes precedence.
If there appears to be a conflict between information in this
addendum and the Installation Addendum for the ET 350 Monitor
with Heater and ET 355 Monitor HL with Heater, the latter takes
precedence.
Important
For more detailed definitions of hazardous locations, refer to the
UL web site <http://www.ul.com>.
Important
The ET 355 monitor HL is a component. After the monitor is
installed in a hazardous location for which it is certified, the whole
system or end product of which it is a part must be inspected to
confirm seal ratings and compliance with all electrical codes. If
your ET 355 monitor HL comes with the KVM extender option, it
is not necessary to have the KVM local unit evaluated since the
local unit is not to be situated in a hazardous location.
