4 Commissioning, SK 200E
The SK 200E inverter series can be commissioned in various ways:
a) For simple applications (e.g conveyor applications) by means of the DIP switches integrated into the
SK 200E (inside) and potentiometers (externally accessible).
In this configuration the plug-in EEPROM is not required.
b) Through adaptation of parameters using software via the ParameterBox (SK CSX-3H or SK PAR-
3H) or NordCon PC - supported software.
Here, the parameterised data is stored in the plug-in EEPROM. This must therefore always remain
plugged in during operation.
ATTENTION
DANGER TO LIFE!
The frequency inverter is not equipped with a line main switch and is therefore always live when
connected to the power supply. Live voltages may therefore be connected to a connected motor
at standstill.
NOTE
For commissioning standard applications, a limited number of the frequency inverter inputs and
outputs (physical and I/O bits) have predefined functions. These settings may need to be
changed (Parameters (P420), (P434), (P480), (P481)).
4.1 Commissioning stages
4.1.1
Connection
After mounting the frequency inverter Adapter
Unit on the motor or the wall mounting kit, the
mains and motor cables must be connected to
the relevant terminals (PE, L1, N (/L2, L3)
und U, V, W).
In addition, a 24V DC control voltage supply to
the frequency inverter is essential (connection
to terminals 44/40).
In principle, the frequency inverter can be
operated in this configuration.
(See Section 4.1.3)
NOTE
The necessary 24V control voltage can be implemented by in integrated SK CU4-…-24V) or an
external (SK TU4-…-24V) optional mains unit or a comparable power source (min. 200mA).
