prevented.
Special service tools are available for specific jobs and
should be used when recommended. The use of these
tools will save time and prevent damage to parts.

1.7 Battery safety precautions

Batteries
When servicing batteries, always wear protecting
clothing and glasses.
1 The electrolyte in batteries is a sulphuric acid
solution which is fatal if it hits your eyes, and which
can cause burns if it contacts your skin. Therefore,
be careful when handling batteries, e.g. when
checking the charge condition.
2 Install a sign prohibiting fire, open flame and
smoking at the post where batteries are being
charged.
3 When batteries are being charged, an explosive gas
mixture forms in the cells and might escape through
the vent holes in the plugs.
Thus an explosive atmosphere may form around the
battery if ventilation is poor, and can remain in and
around the battery for several hours after it has been
charged. Therefore:
- never smoke near batteries being, or having
recently been, charged,
- never break live circuits at battery terminals,
because a spark usually occurs.

2 Leading particulars
2.1 General description
The QAS 30 and QAS 40 are AC generators, built for continuous running at sites where no electricity is available or as stand-by in cases of interruption of the mains. The
generator operates at 50/60 Hz, 230/240 V in line-to-neutral mode and 400/480 V in line-to-line mode. The QAS 30 and QAS 40 generators are driven by a fluid-cooled
diesel engine, manufactured by KUBOTA. An overview of the main parts is given in the diagram below.

LTP: Limited Time Power is the maximum electrical power which a generating set is capable of delivering (at variable load), in the event of a
utility power failure (for up to 500 hours per year of which a maximum of 300 hours is continuous running). No overload is permitted on these
ratings. The alternator is peak continuous rated (as defined in ISO 8528-3) at 25°C.
PRP: Prime Power is the maximum power available during a variable power sequence, which may be run for an unlimited number of hours per
year, between stated maintenance intervals and under the stated ambient conditions. A 10% overload is permitted for 1 hour in 12 hours. The
permissible average power output during a 24h period shall not exceed the stated load factor of 100%.

3) At reference conditions unless otherwise stated.
4) Rating definition (ISO 8528-1):
LTP: Limited Time Power is the maximum electrical power which a generating set is capable of delivering (at variable load), in the event of a
utility power failure (for up to 500 hours per year of which a maximum of 300 hours is continuous running). No overload is permitted on these
ratings. The alternator is peak continuous rated (as defined in ISO 8528-3) at 25°C.
PRP: Prime Power is the maximum power available during a variable power sequence, which may be run for an unlimited number of hours per
year, between stated maintenance intervals and under the stated ambient conditions. A 10% overload is permitted for 1 hour in 12 hours. The
permissible average power output during a 24h period shall not exceed the stated load factor of 100%.
5) Specific mass fuel used: 0.86 kg/l.
