5.3.1 Preparations for start-up
WARNING!
Danger from electricity!
Touching live components at the instrument terminals and connecting
cables can cause serious injury or may even be life-threatening.
– It must be verified that the PQC is installed and connected in accordance
with its intended use before power is switched on.
– Cover the instrument terminals
ATTENTION!
Risk to equipment!
If the PQC terminals are wrongly connected, or if the wrong voltages or
signals are applied to them, this can damage the instrument itself and the
installation.
– Verify that all the connections are correct before switching on the power.
1. Verify that the PQC has been correctly installed and connected as described
in Section 5.1 “Mounting at the desired location” and Section 5.2 “Electrical
installation” and that all the connectors supplied with the instrument have been
plugged in.
2. Verify that the earth connection has been made.
3. Ensure, for example by means of a closed door or a suitable cover, that the
instrument terminals can no longer be touched.
4. Switch on the instrument power.
5. Carry out the initial start-up (see Section 5.3.2 “PQC initial start-up”)
