For all lubrication (except electrical moving
or sliding surfaces), use one of the
following:
Klüber Isoflex Topas L32
(part 3AX11333H)
Klüber Isoflex Topas L32N (spray)
(part 15-172-879-201).

Fastener check
Inspect all fasteners for tightness. Both
locknuts and retaining rings are used.
Replace any fasteners that appear to have
been frequently removed and replaced.
Capacitor charging check and contact-
erosion checks
Perform the capacitor charging check
contained in the section describing the
installation check and initial functional tests
(refer to pages 6-9). The key steps of this
procedure are repeated here:
Note: A temporary source of control power
and test leads may be required if the control
power source has not been connected to the
circuit breaker. Refer to the specific wiring
information and rating label for your circuit
breaker to determine the voltage required
and where the control voltage signal should
be applied. When control power is
connected to the circuit breaker, the
capacitors should automatically charge.
1. Close the control power disconnect
device to energize the circuit breaker
control circuit. If not previously charged,
the capacitors should charge
automatically.
2. Use the Close and Open pushbuttons on
the circuit breaker operating mechanism
(refer to Figure 3: Operator panel
controls on page 10) to first close, and
then open the circuit breaker contacts.
Verify contact positions visually by
observing the OPEN/CLOSED indicator
on the circuit breaker. When the
capacitors are fully discharged and
control power is first applied, the red
LED lights while the capacitors are
charging, followed by the green LED
lights when energy storage is sufficient
for circuit breaker operation. The red
LED is off when the green LED lights.
If the LEDs do not conform to this
sequence, check further as follows:
If the capacitors have been fully
discharged for a very long time, charging
time may be significantly longer than
indicated. If capacitor charging time is
much longer than expected on initial
energization, refer to “Capacitor charging
after very long de-energization” on page
40 of the “Maintenance” section of this
instruction manual.
a) Power supply (T1) secondary output
should be 23-25 Vdc (ST1-1 to ST1-2),
and the green LED on the power
supply (104.0 in Figure 2: Operator
controls and discharging capacitors on
page 7) should be on. If the voltage is
incorrect or the green LED is not on,
check the leads to the power supply.
b) If power supply output voltage is
correct, check wires between
connectors 105.2 and 106.3 and the
LED panel (105.1).
c) If wires are undamaged, replace the
controller board (105.0) and all
capacitor boards (106.1) (two or three
depending on rating).
3. In step 2, when the Close pushbutton
was pressed, the circuit breaker should
have closed, and the capacitors should
have recharged automatically. The
meaning of the LEDs (105.1) on the
controller board:
a) Green LED indicates ready (energy
sufficient for OPEN-CLOSE-OPEN
cycle).
b) Yellow LED indicates open possible
(energy sufficient for OPEN
operation). The yellow LED is
illuminated while capacitors are
charging.
c) Red LED indicates error.
4. Perform the magnetic-actuator
discharge check.
a) Initial status: circuit breaker open.
b) Press red Open pushbutton (54.0).
c) Press black Close pushbutton (53.0).
d) Verify main contact status indicator
shows CLOSED.
e) Press red Open pushbutton (54.0)
again.
