Warnings when handling
Static electricity
Static electricity may damage the product. The integrated circuits operates with
very low voltages, and that makes the product extremely sensetive to static
electricity.
Static-protective field service kit
A static-protective field service kit must always be used when the product is
disassembled or modules are being handled, since the internal electronics are very
sensitive to static electricity.
Follow the instructions in the Service Manual and use the ESD-mat for both old
and new modules.
When mains voltage on the product is required, remove the connection between
the product and the ESD-mat. This is important to avoid getting injured by mains
voltage.
