About this guide

This guide contains the very basic information about the mechanical and electrical
installation and start-up of the NETA-21 remote monitoring tool.

Safety instructions

If you need to connect the remote monitoring tool to a control board inside the
drive/converter/inverter, follow the Safety instructions below.
WARNING! Ignoring the following instructions can cause physical injury or
death, or damage to the equipment.
• Only qualified electricians are allowed to install and maintain the drive, converter
and/or inverter!
• Disconnect the drive, converter or inverter to which the option module will be
installed or connected from all possible power sources. After disconnecting,
always wait for 5 minutes to let the intermediate circuit capacitors discharge
before you proceed.
• Switch off all dangerous voltages connected to any control signal connectors in
reach. For example, 230 V AC may be connected from outside to a relay output of
the drive, inverter or converter.
• Always ensure by measuring with a multimeter (impedance at least 1 Mohm) that
there are no parts under voltage in reach.
