3 Installation
Positioning of
the choke
h The choke should be installed close to the converter.
Connection
h Check the data given on the nameplate (voltage supply to the control
section, voltage supply to the power section, load voltage and load current)
against the system data.
v Chapter 2.3 „Order details“
h Check the adaptation of the setpoint inputs.
h Check the switch settings.
PE connection/
FB connection
h Provide a direct connection between the PE of the IPC and the PE of the
supply network. Connect to the PE terminal
of the IPC.
h If necessary, interference emission of the IPC can also be minimised by a
function equipotential bonding. The function equipotential bonding is
connected to the FB terminal of the IPC.
v Chapter 3.1.1 „Correctly wire all components“
Choke
connection
h The choke is connected to terminals C and 1C.
Voltage
supply
h Connect the voltage supply to the control section to terminals L1 and N(L2)
(X109).
h Connect the voltage supply of the power section to terminals U and N(V).
Load
connection
h The load is connected to terminals D and 1D.
h The cable between the load and the IPC should be as short as possible and
not exceed 50 m.
Control inputs The terminal strip for control connections (inputs and outputs) have been laid
out for safe isolation from the supply. To prevent the safe isolation from being
impaired, ensure that all connected current circuits are also safely isolated.
The required auxiliary supplies must be SELV voltages.
Switch-on
sequence The voltage supplies to the control section and to the power section must be
switched on simultaneously.
A
An isolation switch as per VDE 0160/5.3.1 must be wired between
the supply and the converter to be able to disconnect the
converter (all poles) from the voltage supply prior to starting
internal work!
The connection must only be carried out by qualified personnel!
