2.3 Mechanical features
The mechanical features described in this chapter are
standard provided on this generator. For all other
mechanical features, see “Overview of the
mechanical options” on page 80.
2.3.1 Engine and alternator
The alternator is driven by a fluid-cooled diesel
engine. The engine’s power is transmitted through a
direct disc coupling.
The generator houses a single bearing alternator with
a dedicated voltage regulator.
The synchronous brushless alternator has Class H
rotor and stator windings in an IP23 housing.
2.3.2 Cooling system
The engine is provided with a water cooler. The
cooling air is generated by a fan, driven by the engine.
2.3.3 Safety devices
The engine is equipped with low oil pressure and high
coolant temperature shut-down switches.
2.3.4 Bodywork
The alternator, the engine, the cooling system, etc. are
enclosed in a sound-insulated bodywork that can be
opened by means of side doors (and service plates).
The generator can be lifted by using the lifting eye
integrated in the bodywork (roof). To be able to lift
the QAS 60 by means of a forklift, rectangular slots
are provided in the frame.
The earthing rod, connected to the generator’s earth
terminal is located at the bottom of the frame on the
outside.
2.3.5 Control panel
The control panel grouping control module, ON/OFF
switch, etc., is placed at the rear end.
2.3.6 Data plate and serial number
The generator is furnished with a data plate showing
the product code, the unit number and the power
output (see “Data plate” on page 89).
The serial number is located on the right-hand front
side of the frame.
2.3.7 Drain plugs and filler caps
The drain holes for the engine oil, the coolant and the
plug for the fuel, are located and labelled on the
frame. The fuel drain plugs are located; one at the
bottom of the frame and the other at the cubicle side
of the frame.
The drain flexible for engine oil can be brought to the
outside of the generator through the drain hole.
The filler cap for the engine coolant is accessible via
an opening in the roof. The fuel filler cap is located in
the side panel.
2.3.8 Spillage free skid
A spillage free skid with forklift slots allows the
customer to transport the generator easily with a
forklift. It avoids accidental spilling of engine fluids
and thus helps to protect the environment.
The leaking fluid can be removed via drain holes,
secured by drain plugs. Tighten the plugs firmly and
check for leakages. When removing the leaking fluid,
observe all relevant local legislation.
The drain hole can also be used to
guide external fuel tank
connections. When connecting an
external fuel tank, use the 3-way
valves. Refer to External fuel tank
connection (with/without quick
couplings).
