1. General
This motor operating device is mainly intended
for operating indoor types of disconnectors such as
OJON-. The motor operating device can be installed on
the frame of the disconnector by using an adapter set,
consisting of fixing brackets and an adjuster coupling.
The motor operation device normally fitted on the dis-
connector at the factory but can also be installed later
by the customer.
The motor operation device will disengage from the
disconnector after each operation and enable easy
manually operation directly from the disconnector shaft or
extension shaft. Manual operation can also be performed
by operating a lever on the disconnector shaft or by a
hook stick. If any kind of hand operation devices are
used, it should not automatically lock the operation in
the end positions. See fig.A.
2. Standards
The motor operating device compies with the following
standards:
- IEC 265
- voltage test 2 kV, 50 Hz, 1 min, except for the motor
1.5 kV
3. Transport and storage
The motor operating device is delivered installed on the
disconnector or separatly packed in a cardboard box.
The type number is marked on the box. If the device
is to be stored for a long period, it should be stored
indoors in a dry place.
4. Construction
The motor operating device comprises of a motor, gear
wheel, a screw gear and a lifting arm mechanism.
The motor B-2 drives gear wheels B-3 and B-4. Gear
wheel B-4 rotates screw B-6 which pulls nut B-5. The
nut turns the lifting arm B-1, but disengages from the
arm after operation so that it is possible to manually
operate the disconnector directly from the disconnectors
axle. Position limit switches B-S1 and B-S2, break the
motor current and stop the operating device performing
the operation.

6. Installation
1. Operate the disconnector to the closed position.
Notice the limit mechanism on the disconnector
shaft.
2. Determine on which side the motor operation
device is to be installed.
3. Cut the disconnector shaft to length B.
B = 20 mm for OJON 12_
B = 50 mm for OJON 24_
See fig.E.
4. Drill two 9 mm holes in the disconnector frame
for the fixing bracket.
5. Fit one of the fixing brackets to the disconnector
frame, and the other on the motor operating
device.
6. Fit the adjuster coupling to the disconnector
shaft. Rotate the coupling to 45° and tighten the
locking screw F-1. (The locking nut is not needed)
Loosen the adjuster screws F-2 and F-3 until full
play is achieved. See fig.F.
7. Open the cover for the motor operating device.
8. Install the motor operating device, with both the
disconnector shaft and the adjuster coupling
rotate to the closed position. In the closed position,
the lifting arm G-1 points downwards.
9. Check that the shaft of the motor operation de-
vice rotates easily. If necessary loosen the screws
for the fixing brackets and centralise the motor
operation device. Tighten the screws.
Important!
The adjuster coupling has to rotate on the inner
side of the disconnector shaft so that the voltage
withstand level is not reduced. See fig. F.
10. Open the locking screw F-1 and rotate the motor
operating device to the closed position and the
adjuster coupling in the opposite direction as much
as the play allows, and tighten the locking screw
in this position.
11. Drill one 8 mm hole through the adjuster coupling
and shaft for 12 kV disconnectors and two holes
for 24 kV disconnectors, and fit the cotter pins.

12. Tighten the adjuster screw F-2 until the lifting arm
G-1 turns up in line with the slot when the shaft
is rotated at about 40Nm to the closed posi-
tion.(100 N on the operating shaft). Tighten the
locking nut. See fig.G.
13. Operate the disconnector to the open position.
14. Tighten the other adjuster screw F-3 until the lif-
ting arm G-1 turns up in line with the slot when
the shaft is rotated at about 40 Nm to the open
position (100 N on the operating shaft). Tighten the
locking nut.
15. Manually test operate from the shaft of the motor
operation device and check that the disconnector
fully opens and closes.
Check that the lifting arm rotates enough to
enable the nut to move along the slot.
Check also in both the open and closed posi-
tions that the distance from live parts to the
adjuster coupling is:
min. 120 mm for 12 kV
min. 220 mm for 24 kV
16. Make the electrical connections and earth the
motor operating device according to the respec-
tive standards and regulations.
17. Test operate electrically.

7. Electrical connection
Motor operating device
Type: UEMC 40 K6_/1
Circuit diagram: 31 UEMC 187
The motor operating device can be connected to a
operating box or a control unit. Refer to chapter 9 and
15.
Protective m.c.b
The use of a protective mcb in the supply circuit to
the motor operating device is recommended. In order
that the mcb will protect the motor against overload,
the type is to be chosen for the respective voltage as
detailed in point 9.
Alarm circuit
Refer to suggested alarm unit, circuit diagram no.
31 UEMC 151...154.
During normal operation the alarm points are under
voltage.
Alarm condition: When voltage disappears from the
circuit.
Reason for alarm:
- F1 has tripped
- S6 is open
- Voltage to control unit broken
An alternative alarm circuit can be coupled from the
auxiliary contact of the mcb. Refer to accessories,
point 9.
Separation of motor and control circuit
If the motor circuit is to be separated from the control
circuit, wire X1:1-3 and X1:2-4 is to be disconnected,
and a separate DC-voltage is to be applied between
X1:3 and X1:4 in order to operate the unit.
Note that this could effect the operation of the alarm
circuit and m.b.c.
The electrical equipment of the motor operating device
are the motor and limit switches.
Type: UEMC 40 K6_/2
Circuit diagram: 31 UEMC 205
The electrical equipment of the motor operating device
are the motor, limit switches and contactors.
Examples for system connections
The direction of control (ALT.A or ALT.B) is defined by
the alternative methods of mounting, see chapter 5.

8. Operation
a) Manual control
The motor operating device is mechanically disengaged
in both open and closed positions. Manual operation
is by direct turning the shaft of the motor operating
device, extension shaft, or by a hookstick operating a
operating arm. If a manual operating device is to be
used, it should be of the type that does not automati-
cally lock the device in end positions.
9. Accessories

HE 53235
The operating handle is insulated and fitted with an
insulated grip.

b) Motor control
The motor operating device can be electrically operated
with the I- and 0- push buttons. After being manually
operated, the motor operating device may not be in
sync with the disconnector, which means that it must be
operated twice to synchronize, for example open -
close.
