3.4 Operating altitude
This instrument is rated for an altitude of 2000 m (6562 ft) maximum. Use of this instrument at an
altitude higher than 2000 m can slightly increase the potential for the electrical insulation to break
down, which can result in an electric shock hazard. The manufacturer recommends that users with
concerns contact technical support.
Section 4 Installation
This section provides necessary information to install and connect the analyzer. The installation of
the analyzer should be performed in accordance with relevant local regulations.
Electrocution hazard. Do not connect AC power directly to a DC powered instrument.
Electrocution hazard. Always remove power to the instrument before making electrical
connections.
Electrocution hazard. If this equipment is used outdoors or in potentially wet locations, a
Ground Fault Circuit Interrupt (GFCI/GFI) device must be used for connecting the
equipment to its main power source.
Potential Electrocution Hazard. A protective earth (PE) ground connection is required for
both 100-240 VAC and 5 VDC wiring applications. Failure to connect a good PE ground
connection can result in shock hazards and poor performance due to electromagnetic
interferences. ALWAYS connect a good PE ground to the controller terminal.
