Achtung!
ELECTRIC DANGER 230V/50Hz
Read carefully this instruction
Ask for assistance of a qualified electricians
Underwater remotely controlled vehicle GNOM is connected to AC 230 V / 50 Hz power supply and
poses a potential hazard (electric shock or fire).
Underwater vehicle "GNOM" belongs to the category of electromechanical products.
Installation, operation and maintenance of these products must be performed by qualified and
competent persons, acquainted with this user manual.
Buyers and attendant facilities "GNOM" must abide operating instructions to ensure their own
safety, the safety of people around and to minimize the risk of potential damage of the module
when working under water.
The guide should always be available to all persons involved in organization and implementation of
operations with the GNOM modules.
Unless the assembly GNOM is used according to manual, then it meets international standards:
Safety IEC 60065 (GOST R IEC 60065-2002)
Electromagnetic compatibility IEC 61000-6-1-99 (GOST R 51317.6.1, GOST R 51317.6.3-99)
In addition to these general principles, the laws and regulations applicable in each country as well as
the rules and regulations applicable at the place of work with the underwater modules should be
respected.
Sale or transfer of module "GNOM" to the other person may be exercised only with delivery of
operating instructions. In this case the potential risks in the operation of the gnome passes to the
buyer (attendants).
This guide GNOM together with operating instruction is intended to inform the user in order to
ensure correct and safe use of GNOM.

1. DESCRIPTION
1.1 PURPOSE
The product "GNOM" is designed for underwater works. Inspection and control of premises
located under water in coastal and inland waters, as well as in the control of reservoirs and
water works.
The main advantage of remotely operated vehicle is that you can see underwater full-
featured video
Command of underwater module is executed by operator from the shore (or the vessel) by
means of the control module, which is a part of the kit.
The modern computer and telecommunication technologies are used in the device, and
made it easy in handling, compact, light and inexpensive.
These solutions allowed to use thin (only 10 mm diameter) and flexible communication
cable for transmission data, power and video signals to/from vehicle. The special Kevlar
threads have been used to improve the cable's tensile strength. Because of this fact, the
device keeps the highest degree of stabilization what is very important for inspections. The
vehicle has a good maneuverability and can easily turn on the spot.
High-effective electric motors with magnetic couplings and hi-tech electronics are used in
the vehicle, provide the fast speed of the GNOM with low power consumption.
One of the most important features of this device is a possibility to operate it from PC and
via Lan/Internet.
The GNOM, in essence, an underwater helicopter with the video-camera which moves in
any direction according to the operator's instructions.

The system consists of the GNOM underwater vehicle, reel with cable and power supply unit.
Underwater module is protected by polypropylene frame , two waterproof metal casings (hulls) ,
terminated by transparent windows for video cameras (front and rear).
Power modules, control electronics, compass and pressure sensor are mounted inside casings.
The underwater module is powered by five thrusters, fixed to the frame: two horizontal , the two lateral ,
and one vertical .
On the frame can be installed LED light  (the number of LEDs can be varied), the manipulator ⑩, a circular
sector-Sonar .
To ensure buoyancy near neutral buoyancy a float is attached on the frame .
The underwater unit is connected to the control unit with cable which ensure supply of underwater unit ( 180
V), the information from the sensors and video signal from video camera.
The tether is on reel with the slip rings what ensure that you can wind /unwind the cable during operation.
The cable is reinforced with Kevlar fiber to increase the mechanical strength.
The power supply/control module is stored in another waterproof case and consists of a power module and
control electronics. In the case there is also integrated 15 "monitor. On display you can see video pictures of
the underwater module.
On demand it is possible to supplement the system with a video grabber to record a video that you can watch
on the monitor and analyze afterward.

2. USER’S MANUAL FOR OPERATION
The characteristics and a security parameter
2.6.1 Mode of protection against electric shock from the electrical power supply in 1st Class is guaranteed by
following measures:
- Reinforced insulation, power module mounted in plastic waterproof case
- Protection of "grounding" of all conductive parts through PE conductor in AC power module cable
- Mains fuse in interior of the power / control module – on the phase conductors.
2.6.2 Parameters of insulation between conductors of connector module (connected in parallel) and exposed
metal housing parts:
- Insulation resistance at least 20 MOhm at voltage of 500 V DC - measured at relative air humidity 75% and
temperature between + 16  C and + 24  C
- Electric strength - not less than 2120 V DC.
2.6.3 resistance between PE-pin socket module and metal parts of the module - no more then 0.1 Ohm at
current charge 25A.
2.6.4 Another mode of protection against electric shock is to use a earth-leakage breaker in the route of the
line voltage 230V.
Residual current device provides two-pole disconnect of underwater module under partial or total damage of
insulation. Fault current for protection of live parts is 30 mA.
2.6.5 Major critical module components that provide functions against electric shock include:
- AC power cable to the power / control unit
- Fuses
- Plug the AC filter
- Earth-leakage breaker
- The residual current device
- Power - communications cable (between underwater module and power / control module)
WARNING: Replacement of critical components is permitted only for the types mentioned in the
documentation of GNOM and with a valid certificate from the manufacturer.

instructions and is a qualified, trained or instructed person.
Unauthorized person - a person invited or bystanders.
CAUTION!
To minimize the risk of damage the modules "Gnom" and unsafe situations, do not let children, mentally unstable or
extremely behaving persons operate the underwater module.
2.7.1 Connection to the electricity network 230V
The electrical outlet to which you connect GNOM, or extension cable with splitters, must be completely intact and
construction-technically compatible.
A1: Supply voltage 230V AC for additional devices must be made only by means of a cord with power strips in
accordance with the requirements and restrictions specified in the instruction manual.
A2: WARNING!
By working directly with underwater module it is forbidden to connect to a power strip any heating and lighting
equipment as well as various power tools.
Compliance with the requirements of paragraphs A1, A2 ensure the preservation of security and improvement of
electromagnetic compatibility system.
2.7.2 WARNING!
You can not connect to the GNOM and other devices (accessory) to the mains with the following problems:
• Wrong - incorrect wire connections L and N conductors in the appropriate slot.
• without protective earthing conductor.
Note. Checking the correct wiring connections (phase conductor - L) inspects the operator. (E.g. by phase tester)
2.7.3 WARNING!
It is not allowed to repeatedly turn on and off line voltage 230 V at intervals shorter then 5 seconds.
2.7.4 Before starting work as well as during operation, it is necessary to carry out a performance test to detect any
defects reducing the level of safety equipment.
Check:
- Damage (wearing) of contacts, insulators and conductors power cords.
- Increased heating or overheating of connectors insulating material.
2.7.5 Identification and removal of defects in paragraphs 2.7.2 and 2.7.3 should be carried out in the presence of a
qualified person.
2.7.6 Checking the Residual current device
Carry out before any underwater operation at the new location as follows:
• If the requirements of paragraph 2.7.1 are met and connect to the power supply only power module
• Switch on mains voltage button on the control panel
• After 5 seconds press the "TEST" button on the residual current device. It would immediately lead to a safe shutdown
of module
• Switch off the mains voltage button on the control panel. Switch on the current circuit breaker
• Again switch on the power supply button on the control panel. Residual current device must remain switched on.
