The characteristics and a security parameter
2.6.1 Mode of protection against electric shock from the electrical power supply in 1
st
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 b 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.
Measures to ensure security in preparation for the work and operation with GNOM
Classification of persons who may handle with electrical product.
Classification of persons referred to in accordance with the recommendations based on IEC International
Electrotechnical Vocabulary (IES), IEC 61140, IEC 60065.
Qualified person (specialist) - a person who has appropriate education and work experience, allowing him to
avoid and exclude the risk that electrical equipment may create (IES 826-09-01).
Educated person - a person who has undergone specialized training for work on a specific device in
accordance with safety regulations.
Instructed person - a person who has been briefed with the device using or operating under the supervision of
a qualified person which allows to avoid danger and eliminate risks that electrical equipment may create (IES
826-09-02).
Simple person - a person who is neither a qualified person nor an instructed person (IES 826-0903).
Operator - a person performing work at the production facilities in line with its purpose, operating
