1. TRANSPORT
1.1. Unpacking and inspection
Immediately after receiving the drive, check the delivery compliancewith the shipping
specification. Then check whether the drive has not been mechanically damaged during
transport and the data on the nameplate with the order
The drive is delivered in a cardboard package. Drives are delivered to the recipient completely
assembled.
1.2. Storage and transport
For storage and installation, the drives can be transported / transported by any means
of transportation provided they are protected from moisture. During transport, the drives
should be secured against moving and colliding with each other or parts of the vehicle.
2. DESRIPTION
NSW30 motor drives are designed for cooperation with disconnectors, disconnectors and
earthing switches of medium voltage in indoor conditions. The use of the drive allows remote
or local control of the switch installed in the switchgear cubicle. In a simple way, without any
additional changes in the existing switchgear, you can replace the existing pneumatic or
manual drives of the NRK type, thereby introducing a new standard of operation and safety
(remote control option, local or manual)

2.2. Housing box
The housing box is made of steel sheet,
covered with a layer of epoxy powder paint.
The housing cover is attached to the corp
behind
using four self-tapping screws [12]. In the
bottom
parts of the housing, on both sides, are located
embossments with a diameter of 14 mm
allowing
bringing wires to the control system.

2.3. Driving mechanism
Driving mechanism includes:
DC electric motor
Multistage transmission gear
angular gear.
An electric motor drives a bevel gear through a three-gear gear.
As a result of the gear transmission, the maximum drive torque is approx. 300Nm, and the
angle of rotation of the output shaft is limited by the limit switches to 220 °. The casing is
made of steel sheet, covered with a layer of epoxy powder paint. The housing cover is
attached to the body by means of four self-tapping screws [12]. In the lower part of the
casing, a cable gland with a diameter of 14 mm is provided, enabling the supply of control
and supply wires.
2.4. Environmental conditiona
The drives are recommended to be used indoors, in an atmosphere free from aggressive
chemical agents, at ambient temperatures of -5 to + 40 ° C and relative humidity not
exceeding 70%.

4. INSTALATION AND ADJUSTMENT
4.1. Assembling to the supporting construction
The drive is fastened to the supporting structure by means of
two M10 screws. The wall on which the drive is mounted should
be sufficiently rigid, thus ensuring a certain transmission of the
drive torque.
Compatibility between the spacing of mounting holes and the
shape of the output shaft ensures full interchangeability for
manual drives of the type NRK produced by ZWAR S.A and
manual drives NR-1 produced by ZWAE sp. O.o.

4.4. Connecting protective grounding.
For grounding the coupling shaft of the motor drive with
the apparatus, a clamp on the cross-joint is used,
consisting of an M12 screw and washer. The cross-
section of the earthing conductor should be selected in
accordance with the applicable regulations.
4.5. Connecting control and supply circuits.
The control cable must be inserted into the drive housing
via a throttle. Connection of the control cable with the
terminal block of the drive should be made in accordance
with the designed control system. The maximum cross-
section of wires supplied to the terminal block can be 4
mm2.
4.6. Adjusting the roatation angle of the output shaft.

Strona 14 z 20
The angle of rotation of the output shaft is adjusted by means of limit switches [23]
mounted coaxially with the control bracket [24]. Unscrewing the M4 bolt allows you to
move the control bracket with the connector to the cam on the shaft, and this allows you
to smoothly adjust the angle of the output shaft in the range of 220 degrees.
4.7. Tests before putting into service
Before testing the drive, check the quality of its assembly and the correct interaction with the
device. For this purpose, 10 - 20 electrically controlled shifts should be made, carefully
observing the interaction of the parts. In the case of any irregularities in the operation of the
drive or the apparatus cooperating with it, a re-adjustment of the respective assemblies
should be carried out and the tests should be repeated.
5. EXPLOITATION
5.1. Manual control

Strona 15 z 20
In order to manually maneuver the drive:
(1) insert the notch of the drivelever [10] into the lock handle [9]
(2) swing the lever in the direction indicated in the sketch
For version with BE-2 blockade:
(2.1) Press the lock release button
(2.2) Slide the drive shaft slide gate with your fingers
(4) put the lever on the drive shaft
(5) rotate to close the apparatus (right) or open(left) depending on the current position of the
apparatus.
After completing the maneuver, lower the grip handle [9] and retract the drive lever [10].
ATTENTION: After manual override, check whether the drive shaft has been engaged, i.e.
retraction to the original position (the shaft flange must be adjacent to the cam causing the
shaft to move away).
If the coupling is not engaged, turn the drive shaft a few degrees to the right or to the left.
6. PERIODIC INSPECTIONS AND CONSERVATIONS
6.1. Visual inspaction

Strona 16 z 20
Visual inspection is recommended to be carried out once a year and after any failure or short
circuit in the switchgear. Check especially:
a) the state of the earth terminal,
b) the state of the coupling mechanisms,
c) the condition of external parts (housing).
d) connection of wires with terminal block, fixing of limit switches.
6.2. Spare parts and recommended maintenance metarials.
The use of high quality components and operational experience indicate the long service life
of motor drives (about 30 years). In the event of damage to the drive due to improper
assembly or operation, it is possible for themanufacturer to pay for repairs.
PHARMACEUTICAL WHITE (acid-free) used for the lubrication of electrical contacts
(grounding, contacts of HV switches)
PROTECTION GREASE TDM according to PN-64 / C-96146 used for the preservation of metal
surfaces (shaft articulation elements and coupling mechanism).

11.UTILIZATION
NSW30 drives are made of materials that are recyclable.
The main materials from which the disconnectors are built are:
steel (painted, galvanised);
aluminum;
plastics (epoxy mix, polyamide).
The drives do not contain any dangerous substances. In accordance with applicable
regulations, it is possible to return a worn out, complete disconnector to the
manufacturer.
