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.
Multiple hazards. Only qualified personnel must conduct the tasks described in this section of the
document.
Install the device in a location and position that gives easy access to the disconnect device and its operation.
Potential Instrument Damage. Delicate internal electronic components can be damaged by static electricity,
resulting in degraded performance or eventual failure.
4.1 Portable mounting
Install the instrument on a laboratory table, on a clean flat surface in a safe area. Locate the
instrument convenient to the power source connectors, supplies and the PC. When carrying the
instrument, grip the top handle firmly, and gently place it on the working surface. Avoid putting the
instrument on the floor. The instrument provides two folded legs hidden in the lower frame. Pull them
out to modify the display angle.
