Earth Ground Connection
CAUTION
The neutral of the generator set may be required to be bonded to earth ground at the generator set
location, or at a remote location, depending on system design requirements. Consult the engineering
drawings for the facility or a qualified electrical design engineer for proper installation.
NOTICE
• The end user is responsible to make sure the ground connection point surface area is clean and free of rust
before making a connection.
• The end user is responsible for making sure that an earthing arrangement that is compliant with local conditions
is established and tested before the equipment is used.
High Temperature
DANGER
• The silent generator set doors must be closed securely when the generator is operating. Do not
get close to or touch the exhaust pipes and mufflers, radiator, cylinder cover, engine block and
generator housing to prevent severe scald.
• The generator will remain hot for several minutes after shutting down. Inspection and
maintenance of the generator set must be done only after the generator set is fully cooled
down.
• If any check or service must be made while the unit is running, use extreme caution around hot
manifold, moving parts, etc.
• Engine coolant is very hot and under high pressure. Don’t open the radiator cap until the engine
is completely cooled, otherwise steam and hot water will be released and cause severe
personal scald.
• Inspect the coolant level every time before operating generator set. Service cooling system
before operating the unit or when the engine is completely stopped and the coolant temperature
falls to 50 C.⁰
Battery
WARNING
• The battery can produce combustible gas leading to an explosion or serious injury.
• Charge the battery only in a well-ventilated area to prevent an explosion.
• When connecting the battery cables, connect the positive terminal first and then the negative terminal. Observe
proper polarity to prevent a short circuit or sparks which could ignite the combustible gas produced by the
battery.
• Turn off the battery switch or disconnect battery when performing maintenance on the generator.
• The electrolyte of the battery is diluted sulfuric acid which can cause severe burns. If electrolyte contacts the
skin or clothing, immediately flush with large amounts of clean water. If electrolyte gets into the eyes, rinse the
eyes with a large amount of water and seek immediate medical treatment.
• Inspect the storage battery after the engine is stopped.
Noise Level of silent generator set
CAUTION
• The noise level of the generator set is significantly increased with the doors open.
• If the unit has to operate with the door open, such as during an inspection, the operator shall
wear protective ear plugs to prevent permanent hearing loss.
Noise instructions:
The noise level listed in this manual is not safety working level but emission level. There is a linkage
between emission level and noise level. The emission level cannot be regarded as the standard to
decide whether the noise protection measures need to be taken.
Factors affecting the actual noise level includes the operating ambient conditions and other noise
sources (The quantity of the generators, working hours in the noisy environment, etc.) .
