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.

Safety
WARNING! Obey the safety instructions during the start-up procedure. See chapter Safety
instructions on page 13.
Checks/Settings with no voltage connected
Check the mechanical and electrical installation of the drive.See Installation checklist on page 105.
Drives with Pt100 relays (oL506):
• 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.
Powering up the drive
Close the cabinet doors.
