2. USER’S MANUAL FOR OPERATION
Requirements for location and climatic conditions of use
2.1 Conditions and procedure operation at aplication site should minimize the risk of dangerous situations
and possible damage of underwater module GNOM during all work time.
Electrical socket, control unit and cable assemblies (reel) must be protected:
• from direct exposure to precipitation (rain, snow, dew)
• from harmful effects by animals, rodents and insects
• from fall in water and immersion in water
• from the careless treatment of other person
NOTE: If the ambient temperature exceeds + 20 ° C, the control unit must be protected against overheating
by solar radiation.
2.2 At the first signs of impending storm is required to cease immediately underwater operations and unplug
the device from power supply (socket).
It is forbidden to keep the device connected to electricity after termination of work. After end of work always
remove the power plug from the outlet.
2.3 Gnome is designed for use in following climatic conditions:
• air temperature: from -20 ° C to 45 ° C;
• Relative humidity (non-condensing): max 98%
• Atmospheric pressure, mm Hg. : From 630 to 800
2.4 The communications between control unit and underwater module via cable is guaranteed at air
temperature from -- 20 ° C to +45 ° C and a water temperature of -5 ° C to +45 ° C.
2.5 Electrical Characteristics
2.5.1 Supply voltage 230 VAC, 50 Hz.
Power / control module operates in the range of supply voltage from 198V ~ to ~ 242v
2.5.2 Total consumption for "GNOM" depends on the configuration of assembly et does not exceed 2000W.
2.5.3 Supply voltage in network must be in compliance with specification GOST 13109-97 and allowable pulse surges
from lightning and other switching phenomena refers to category II (up to 2.5kV)
2.5.4 Connection of kit GNOM to network (source) is made via three-wire power cable.
CAUTION:
A network cable is included in delivery kit.
Never substitute cable by another cable with unknown parameters, respectively without its control!
2.5.5 Power of underwater module is realized from power / control module assembly. Supply voltage of underwater
module is 180 V DC. The module is connected to the power supply via the cable (10 mm) which comes on the reel.
Operating current of underwater module is not higher than 10A.
