HYDRAULIC GENERATORS
GENERAL
Rubber cushions (R)
Rubber cushions are attachments between HG hydraulic generator and its base
machine. If HG hydraulic generator comes with rubber cushions, grounding of the
generator have to be ensured.
NOTE!
READ CHAPTER „4.4. Grounding“ to see proper grounding for the HG
hydraulic generators.
Without automatic frequency regulation (S)
Without automatic frequency regulation generator does not have any automatic
rotation or frequency control.
NOTE!
Customer is responsible of controling the suitable oil flow and rotation
speed of the hydraulic motor, if an automatic frequency regulation isn´t
provided.
Silence-Motor (E)
An additional hydraulic motor option which noise level is reduced. Silence-motors
are used when low noise level is required.
1.9. ELECTRIC EQUIPMENT
The product identification key describes which electric equipments are included
in HG hydraulic generator’s structure.
All DYNASET HG hydraulic generators except the cable model (K), include fuses
and either a residual current device (V) or a residual current circuit breaker device
(Y). Other electric equipment are optional.
Cable connection (K)
Generators with cable connection come only with cable output. These models
don´t have any electrical safety devices such as fuses and residual current device
circuit breakers on them.
Residual current device (V)
A residual current device (RCD) responds to current leakages by switching the
current off if the current difference between phase and neutral is more than 30
mA.
RCD has a test button to test its proper operation in fault condition. When the
test button is pressed it safely creates a small leakage condition which releases
the switch. RCD is to be tested monthly. READ CHAPTER „6.4. Test Safety devices“.
The RCD (V) includes a residual current circuit breaker device (RCCBD) which
functions are presented in the equipment (Y).
