Start-up

Contents of this chapter

This chapter contains the start-up procedure of the drive. The default device designations
(if any) are given in brackets after the name, for example "main switch-disconnector (Q1)".
The same device designations are also used in the circuit diagrams, typically.

Checks/Settings with no voltage connected

Check the mechanical and electrical installation of the drive.See
Drives with ground fault monitoring for IT (ungrounded) systems (option +Q954): Adjust the settings
of the ground fault monitor to suit the installation. See the circuit diagrams of the delivery and
IRDH275B Ground Fault Monitor Operating Manual by Bender (code: TGH1386en).
Drives with Pt100 relays (options +L506):
• Check the connections against the circuit diagrams of the delivery.
• Set the alarm and trip levels of the Pt100 relays.
Set the alarm and trip levels of the Pt100 relay as low as possible based on the operating
temperature and test results of the machine. The trip level can be set, for example, 10 °C higher than
what the temperature of the machine is at maximal load in the maximum environmental temperature.
We recommend to set the operating temperatures of the relay, typically for example, as follows:
• 120...140 °C when only tripping is in use
• alarm 120...140 °C and trip 130...150 °C when both alarm and tripping are used.
