2 Application and handling instructions
Please provide static discharge protection during handling. As long as the board is not completely
assembled, the input terminals have to be short-circuited. Persons working with devices have to wear a
grounded bracelet. Any synthetic floor coverings must not be statically chargeable. Even during
transportation the input terminals have to be short-circuited using, for example, conductive rubber.
Worktables have to be grounded.
When first operating a newly developed circuit, SEMIKRON recommends to apply low collector voltage
and load current in the beginning and to increase these values gradually, observing the turn-off
behavior of the free-wheeling diode and the turn-off voltage spikes generated across the IGBT. An
oscillographic control will be necessary. Additionally, the case temperature of the module has to be
monitored. When the circuit works correctly under rated operation conditions, short-circuit testing may
be done, starting again with low collector voltage.
It is important to feed any errors back to the control circuit and to switch off the device immediately in
failure events. Repeated turn-on of the IGBT into a short circuit with a high frequency may destroy the
device.

3 General description
The SKiiP®4 F-Option Board allows the controlling of SKiiP®4 system by means of fiber optics. There are three
variants of SKiiP®4 F-Option available:
- Variant 1: L5066401 SKiiP®4 F-Option with D-Sub connector, no plastic case
- Variant 2: L5066402 SKiiP®4 F-Option with D-Sub connector
- Variant 3: L5066403 SKiiP®4 F-Option without D-Sub connector
In case of using SKiiP®4 F-Option the two switching signals (TOP/BOT) and the GPIO error signal are
transferred via optical connection. In addition the analogue signals as well as the CAN-Bus signals are
available on the D-Sub connector X2 for Variants 1 and 2 of F-option boards described above.
The electrical connection between SKiiP®4 F-Option board and SKiiP®4 driver must be realized by 25-wired
ribbon cable. The built-in connector of the SKiiP®4 F-Option board can be directly plugged in case of mounting
SKiiP®4 F-Option on the SKiiP®4 top cover (Variants 2 and 3) or on SKiiP®4 Paralleling Board (Variant 1). In
other cases the usage of cable extention up to 1,5m is allowed. On the other side it must always be connected
to the SEMIKRON “SKiFace Standard” interface of SKiiP®4 driver by a 25-pin D-Sub female connector. Please
refer to the Technical Explanation SKiiP®4 for pin assignment of connector X1.
The example of SKiiP®4 F-Option board application for Variant 1 is shown in the Figure 3.1.
Figure 3.1: SKiiP4 F-Option board (Variant 1) application example with connected SKiiP®4 system
Please note that in case of mounting SKiiP®4 F-Option board (Variant 1) on the SKiiP®4 Parallel board the
SKiiP®4 Parallel board variant compatible to the F-Option board should be chosen. The following SKiiP®4
Parallel boards are compatible to the F-Option Board (Variant 1):
L5064204 (paralleling of 4 SKiiP®4 systems),
L5064205 (paralleling of 3 SKiiP®4 systems),
L5064206 (paralleling of 2 SKiiP®4 systems).
Pollution degree class 2 and IP00 shall be considered for all SKiiP®4 F-Option boards.

6 Mounting Instruction
6.1 Mounting Instruction for F-Option Board Variants 2 and 3
The mounting process for both Variants 2 and 3 is identic, the description below is shown on example of F-
Option board Variants 2.
The F-Option plastic housing consists of two parts: bottom part (Figure 6.1, left) and top cover (Figure 6.3, left).
1. The bottom part should be placed on the SKiiP®4 top cover so that the snap-fits with larger distance (see
green arrows Figure 6.1) match to the slots of SKiiP®4 top cover. Afterwards the other side should be
pressed inside applying slight pressure (see red arrows Figure 6.1) till the click is audible.
Figure 6.1: Mounting of bottom part of plastic cover SKiiP4 F-option board
2. The PCB can now be inserted in the bottom part of the F-Option housing (Figure 6.2), where it will be fixed
by pressure parts at the sides (see blue arrows Figure 6.2). One edge of the PCB and housing is cut off
(see red arrow Figure 6.2) to avoid the reversed placing of PCB. It is recommended to insert the PCB into
the housing at the beginning on one side and then to press it inside on the other side applying slight
pressure. Please check the screw holes on PCB match to the holes of bottom part of plastic cover.

3. The next step is mounting of the top part of the plastic housing SKiiP®4 F-Option. Please take care that the
snap-fits of bottom part match to the snap-fits of the top cover of the housing (see red arrows Figure 6.3,
the cable connection between F-option Board and SKiiP®4 is not shown).

Figure 6.4: Mounting of the top part of the plastic cover SKiiP®4 F-option board, final view
4. The PCB should now be fixed with 4 screws Ejot Delta PT 40x18 T20, order number: 4230435809, in the
bottom part of the F-Option housing (please see Figure 6.4, blue arrows). Please use the screws included
in delivery. The screwing parameters should be set up as follows:
Screwer to be used (Bit): T20 Torx
Rpm: 500 –600 U\min
Torque for the first time screwing: 1,8 Nm
Torque for the next screwing (manually, without rpm control): 1,2 - 1,4 Nm
By inadequate setting of screwing parameters mounting problems can occur, e.g. loosing of top cover or
thread damage.
6.2 Mounting Instruction for F-Option Board Variant 1
Please refer to the Technical Explanation SKiiP®4 Parallel Board for information about mounting of F-Option
SKiiP®4 Variant 1 on the SKiiP®4 Parallel Board.
It is also possible to use F-Option SKiiP®4 Variant 1 as a spare part replacement for Varant 2. In this case it
must be inserted into the plastic housing as decribed in the chapter 6.1.

10 Optical Input/Output Signals
10.1 PWM TOP/BOT Signals
The PWM TOP/BOT optical signals could be described as follow: by recognised incoming light the IGBT will be
switched on, by no light the IGBTwill be switched off. Please see Table 4.
Table 4: PWM TOP/BOT optical signals
Optical Receiver receives light
Optical Receiver receives no light
IGBT ON
IGBT OFF
Please note: A non-connected optical link will be considered as LOW signal (IGBT OFF).
If the light intensity is not sufficient the IGBT might stay off and an ERROR_OUT signal might be set. To avoid
this the minimal transmitter current IFdc at the controller side should be at least 50 mA. Please see Figure 10.1
for example of the circuit for transmitter LED at the controller side.

The HALT signals of all SKiiPs in the application and from other hardware components can also be connected
together. That means that the HALT signal is set to LOW state when one of the connected SKiiPs is not ready
to operate. In this case only one receiver circuit on the user controller board is necessary. In case of failure the
switch off time for all such connected susystems will be shorter, than for SKiiPs with separately processed
HALT-signals.
