2.1 Anti-static Precautions
WARNING:
Failure to take ESD precautions during the installation may result in
permanent damage to the product and severe injury to the user.
Electrostatic discharge (ESD) can cause serious damage to electronic components,
including the PM-PV-D4251/N4551/D5251. Dry climates are especially susceptible to
ESD. It is therefore critical that whenever the PM-PV-D4251/N4551/D5251 or any other
electrical component is handled, the following anti-static precautions are strictly adhered
to.
Wear an anti-static wristband: Wearing a simple anti-static wristband can
PM-PV-D4251/N4551/D5251 User Manual
help to prevent ESD from damaging the board.
Self-grounding: Before handling the board, touch any grounded conducting
material. During the time the board is handled, frequently touch any
conducting materials that are connected to the ground.
Use an anti-static pad: When configuring the PM-PV-D4251/N4551/D5251,
place it on an antic-static pad. This reduces the possibility of ESD damaging
the PM-PV-D4251/N4551/D5251.
Only handle the edges of the PCB: When handling the PCB, hold the PCB
by the edges.
2.2 Unpacking Precautions
When the PM-PV-D4251/N4551/D5251 is unpacked, please do the following:
Follow the anti-static precautions outlined in Section
Make sure the packing box is facing upwards so the
PM-PV-D4251/N4551/D5251 does not fall out of the box.
Make sure all the components shown in the unpacking section are present.
