Electrostatic Discharge (Esd) Considerations; Prepare The Wiring - Hach 2200 PCX User Manual

Electrical shock and fire hazards. Make sure to identify the local disconnect clearly for the conduit
installation.
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.
Electrical shock and fire hazards. Make sure that the user-supplied power cord and non-locking plug
meet the applicable country code requirements.
Electrocution hazard. Make sure that there is easy access to the local power disconnect.
Electrical shock hazard. Externally connected equipment must have an applicable country safety
standard assessment.
Install the cover after all the connections are made to keep the environmental enclosure rating.
The electrical connections to power the instrument are made at the factory. Make sure to use an
electrical outlet that is above flood stage areas. It is necessary to set the power to off and then to on
for some programming functions. When all of the connections are made, connect the power cord to
an electrical outlet.. Refer to

Electrostatic discharge (ESD) considerations

Potential Instrument Damage. Delicate internal electronic components can be damaged by static
electricity, resulting in degraded performance or eventual failure.
Refer to the steps in this procedure to prevent ESD damage to the instrument:
• Touch an earth-grounded metal surface such as the chassis of an instrument, a metal conduit or
pipe to discharge static electricity from the body.
• Avoid excessive movement. Transport static-sensitive components in anti-static containers or
packages.
• Wear a wrist strap connected by a wire to earth ground.
• Work in a static-safe area with anti-static floor pads and work bench pads.

Prepare the wiring

Figure 8 shows the wire connection to the terminal blocks. Remove the wire insulation by 6.35 mm
(0.25 in.) before the installation. Make sure that the wire is fully installed in the connector so that no
bare wire shows.
