2.1 Anti-static Precautions
WARNING:
Failure to take ESD precautions during installation may result in permanent
damage to the DRPC-124-EHL Series and severe injury to the user.
Electrostatic discharge (ESD) can cause serious damage to electronic components,
including the DRPC-124-EHL Series. Dry climates are especially susceptible to ESD. It is
therefore critical that whenever the DRPC-124-EHL Series 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
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 DRPC-124-EHL Series, place
it on an antic-static pad. This reduces the possibility of ESD damaging the
DRPC-124-EHL Series.
2.2 Unpacking Precautions
When the DRPC-124-EHL Series is unpacked, please do the following:
▪Follow the anti-static precautions outlined in Section 2.1.
▪Make sure the packing box is facing upwards that the DRPC-124-EHL Series
does not fall out of the box.
▪Make sure all the components shown in Section 2.2 are present.
