c) Press black Close pushbutton (53.0).
d) Verify main contact status indicator
shows CLOSED.
e) Press red Open pushbutton (54.0)
again.
f) Verify main contact status indicator
shows OPEN.
5. De-energize the control power by opening
the control power disconnect device in
the relay and control compartment.
Remove the mechanism housing cover
sheet (60.1). Do not unplug connector
(106.3) from the capacitor boards, or
damage to the capacitor board or the
controller board may occur. Fast discharge
the capacitors (106.2) by unplugging the
connector (105.2) on the capacitor
controller board (105.0). During fast
discharge of the capacitors, a red LED on
each capacitor board will flash, indicating
that discharge is in process. The process is
complete when the red LED stops
blinking.
6. After the fast discharging process is
complete, plug in the connector (105.2)
to the controller board (105.0).

1. Energize control power circuit by closing
the control power disconnect device
shown in Figure 8: Relay and control and
operator compartments for type SDV7-MA
circuit breaker with magnetic-actuator
operator on page 30. The LEDs (105.1)
should show the progress of capacitor
charging.
2. Use the Close pushbutton on the circuit
breaker operating mechanism (refer to
Figure 7: Operator controls and
discharging capacitors on page 26) to
close the circuit breaker.
3. Use the manual opening handle on the
right side of the enclosure (refer to Figure
8: Relay and control and operator
compartments for type SDV7-MA circuit
breaker with magnetic-actuator operator
on page 30) to open the circuit breaker.
4. Attempt to close the circuit breaker using
the pushbutton on the circuit breaker
operating mechanism (refer to Figure 7:
Operator controls and discharging
capacitors on page 26). The circuit
breaker should not close.
5. Reset the manual opening handle to
NORMAL position by pulling the retainer
pin out.
6. After resetting the manual opening
handle to NORMAL position, attempt to
close the circuit breaker using the
pushbutton on the circuit breaker
operating mechanism. The circuit breaker
should close.
7. Open the circuit breaker using the
pushbutton on the circuit breaker
operating mechanism.
8. Open control power circuit by opening
control power disconnect shown in Figure
8: Relay and control and operator
compartments for type SDV7-MA circuit
breaker with magnetic-actuator operator
on page 30.
Final mechanical inspection and testing
without control power
Before the circuit breaker is energized, it must
be thoroughly inspected and tested. Correct
any deviations before energization.
Spring-loaded mechanism.
Can result in moderate injury.
When handle is in TRIP or CLOSE BLOCKED positions, pulling release pin
causes handle to return to NORMAL position very rapidly. Keep hand clear of
handle when pulling release pin.
