1. Safety instructions
Danger: Risk of fatal injury from electric shock
Parts of the system are live. During installation and connection:
►Do not touch parts of the system.
►Make sure that the power supply has been disconnected and the
system is dead.
►Switch the ATICS® to manual mode and to switch position "0".
►Lock the changeover device with a padlock to prevent it starting
accidently.
Warning: Risk of destruction if mains voltage incorrect
►The permissible mains voltage is indicated on the nameplate.
Caution: Avoiding incorrect insulation measurements
Only one insulation monitoring device may exist in an IT system to pre-
vent erroneous measurements. ATICS® includes an insulation monitor-
ing device.
►Do not connect additional insulation monitoring devices.
Danger: Risk of fatal injury from electric shock
Connecting wires can come loose and fall out if the ferrules being used
are too short, the wire ends are tinned or the connection screws have
not been tightened enough.
►Consider a stripping length of 20 mm and do not use ferrules
when connecting lines 1, 2 and 3.
►Use a torque wrench to tighten the terminal screws. Check all
the screws on a regular basis to make sure they are seated
tightly.
Warning: Risk of destruction when insulation and voltage
tests are being carried out
►Disconnect the device from the mains for the duration of the
test.

8. Mounting the ATICS® on DIN rail
1. Place the ATICS® on the top edge of the rail.
2. Use a screwdriver to pull down the lower yellow slide lock (C)
and snap the ATICS® into place with slight pressure. Check that
the slide lock is properly snapped into position by pulling
slightly the lower part of the enclosure.
3. Secure all terminals including the unused terminals with Allen
screws.
Tightening torque: 5 Nm.
4. Fasten the terminal covers.
Tighten the mounting screws (D) (PZ1, 8.8 lb-in, 1 Nm).
Caution: If the screws are not tightened, ATICS can be damaged
by the vibrations of the switch-over.
9. Mounting the ATICS® on mounting plate
Warning: Screw heads or washers reduce voltage clearance
Provide for sufficient clearance to live conductors (voltage clearance) by using mounting screws with flat screw heads and flat washers. If mounted on
electrically conductive material: the mounting plate has to be earthed and the area under the terminals has to be covered with insulating material. It is
the responsibility of the mounting staff to select the appropriate mounting plate and mounting screws and to keep the prescribed torque setting.
1. Undo the Allen screws of the terminals (C).
2. Remove the green connectors (D) top and bottom
3. Remove the black bridge (E) bottom
4. Fasten the ATICS® to the mounting plate with M5 (22 lb-in, 2.5
Nm) mounting screws (see dimension diagram).
5. Insert the black bridge (E), bottom
6. Plug in the green plug connectors (D) top and bottom
7. Tighten the Allen screws on the terminals (C).All terminals,
including the unused terminals must be fully tightened.
Tightening torque: 5 Nm.
8. Fasten the terminal covers.
10. Fastening, inserting and securing connections
Connect the terminals according to the wiring diagram to the plug
connectors (A, B) and the three connector plugs (C).
•Connect the lines 1, 2 and 3 to the plug connectors (A, B) with
a Torx® screwdriver T20 or a slotted screwdriver 6.5 x 1.2 mm.
Consider a stripping length of 20 mm and do not use ferrules.
Tightening torque: 2.5 Nm (≤ 25 mm²) or 4.5 Nm (≥ 25 mm²).
The connecting wires must be laid so that they are short-cir-
cuit and earth-fault proof!
•Connect the connector plugs (C) with a slotted screwdriver of
2.5 x 0.4 mm. Stripping length: 7 mm. Tightening torque:
0.22…0.25 Nm.
1. Insert bottom green plug connector (B) and secure with
mounting screws. After that, insert top green plug connector
(A) and secure with mounting screws.
2. Insert the other three connector plugs (C).
3. ATICS…400 only: Connect connector plug on the top of the
housing (opposite side of (C)).

Fault/message Description Remedy
Mains power connection Connection to the IT system interrupted or voltage in the system
being monitored below 150 V
→Check connection of ports L1/IT, L2/IT to the IT system.
Check voltage in the IT system.
Earth connection Connection to PE interrupted →Check that the E and KE are connected to the protec-
tive earth conductor by two separate lines on.
Device error + Errorcode For details about actions to be taken refer to table section "Error code/service code“. The message is on channel 6 of the BMS bus.
Short-circuit distribution board Short-circuit detected →Eliminate short-circuit
Failure distribution board No voltage on Line 3, contact of the changeover switch defective →Replace the ATICS®.
Overcurrent I(3) Short circuit or interruption of the connection cable was detected:
Measuring current transformer STW3 (T3), channel 7
→Eliminate the cause of overcurrent.
→Eliminate any damage.
CT connection
CT short-circuit
Measuring current transformer STW3 (T3), channel 7 →Check connecting wire of measuring current trans-
former
No MASTER There is no device with master function available on the RS-485
interface
→Check BMS bus connection cable.
→Check whether master has failed or whether its ad-
dress has changed. If the device is operated without
BMS bus, the "Failure monitoring" must be switched
off (setting menu 8: interface).
Service: __ (date) Reminder for next service →Agree date with Bender Service
Test: __ (date) Reminder for next test →Plan date for test.
→Carry out test.
Manual mode
Message "Manual mode" although manual mode has not been activated
→Check the connections of the digital input.
Error during the changeover
process
When the test set-ups do not supply enough current for switching
the coils of the ATICS. →Only use test set-ups that provide the necessary peak
current of 17 A.
Error code/Service code Description Remedy
1.xx, 4.xx, 9.xx Fault message from the internal memory monitoring →Contact Bender Service.
3.11 Max. number of hours exceeded →Plan device replacement
3.12 Max. number of changeovers exceeded →Plan device replacement
3.13 Changeover due to overcurrent or shortcircuit detected. These
changeovers reduce the life of the device. Currents which are
measured in excess of 130 A are evaluated as overcurrents or short-
circuit currents.
→Have personnel assess the short-circuit load.
→Contact Bender Service.
3.5 Service has been carried out.
This is not a fault message. Display only on service logger.
→No action required
6.xx, 7.xx, 8.1x
Device error. The internal self monitoring of the device has detected a
fault which could impair the safe operation of the device.
→Replace the device immediately.
8.21 … 8.30
Fault Isometer or transformer monitoring →Reset, then execute test of the IT system
→Check that the current firmware is installed.
→When no fault is being displayed: OK. Otherwise re-
place the device.
→Check that the bridge on the output side is properly in-
stalled.
8.22
Temperature sensor faulty or earth potential tainted. →Disconnect the temperature sensor (Z1/Z2). If no error
is displayed: replace temperature sensor or correct its
wiring.
8.51 … 8.52
Fault internal power supply unit. →RESET -> execute alarm, then test the changeover
function.
→If fault persists: device replacement.
→Only use test set-ups that can supply the necessary
peak current
8.61 … 8.66 Fault during changeover process.
Occurs when the voltage on the new line fails during the
changeover.
Also occurs when the test set-ups do not supply sufficient current for
switching the coils of the ATICS.
→RESET -> execute alarm, then test the changeover
function.
→ If fault persists: replace the device.
→ Only use test set-ups that provide the necessary peak
current of 17 A.
→ In the settings menu 1: Select changeover t(0)≥160 ms.
