Warning!
During the operation of electrical equipment, certain parts of these devices are
normally under dangerous voltage,and mechanical parts, also remotely controlled,
can move quickly.
Failure to follow the warning instructions canresult in serious personal injury or
material damage.
Only suitably qualified personnel can work on or near the device. These personnel
must know exactly all safety rules and maintenance rules in accordance with these
instructions.
The trouble-free and safe operation of this device requires proper transport, proper
storage, construction and assembly as well as careful service and maintenance.

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.
[12] sheet metal srews, [1] casing
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%.
