Electrostatic Discharge (Esd) Considerations; Wiring For Power - Hach LANGE WDMP sc Manual Del Usuario

D A N G E R
Electrocution hazard. Do not connect AC power directly to a DC
powered instrument.
D A N G E R
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.
D A N G E R
Electrocution hazard. Protective Earth Ground (PE) connection is
required.
D A N G E R
Electrocution hazard. Use only fittings that have the specified
environmental enclosure rating. Obey the requirements in the
Specifications section.
W A R N I N G
Electrical shock hazard. Externally connected equipment must have an
applicable country safety standard assessment.
W A R N I N G
Electrical shock and fire hazards. A local disconnect is needed for a
conduit installation.
W A R N I N G
Electrical shock and fire hazards. Make sure to identify the local
disconnect clearly for the conduit installation.

W A R N I N G
Electrical shock and fire hazards. For a cord-connected instrument,
make sure to install the instrument so that the cord can be
disconnected easily from the supply socket.
N O T I C E
Make sure that the equipment is connected to the instrument in accordance with
local, regional and national requirements.

Electrostatic discharge (ESD) considerations

N O T I C E
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.

Wiring for power

D A N G E R
Electrocution hazard. Always remove power to the instrument before
making electrical connections.
N O T I C E
Install a local disconnect switch or circuit breaker with sufficient current capacity
for the panel and that breaks all mains powered (hot) conductors. Clearly mark
the disconnect or circuit breaker for the panel.
