GENERATORS

3 SAFETY REGULATIONS

3.1 Precautions

Carefully read the Instruction and Maintenance Manuals
before starting up and using the machine.
The manufacturer declines any responsibility for dam-
ages to persons or things stemming from noncompliance
with the safety standards.
Carefully examine the safety panels applied to the ma-
chine and follow their contents to the letter.
- Do not allow unqualified or inadequately trained person-
nel to use the generator.
- Keep children or animals away from the generator when
it is running.
- Do not approach the generator with wet hands as it is a
potential source of electrical shock if improperly used.
- Do not perform any operations on the generator unless
the motor is off; tests which require the motor to be
running must only be performed by specialized personnel.
DANGER
When the generator is connected to an automatic
start-up panel, before any tests or maintenance can be
performed, it must be locked out - by selecting the
BLOCK function - or disconnected - by disengaging
the connector.
- The exhaust fumes contain carbon monoxide and other
harmful substances; never run the unit in an inad-
equately ventilated area.
- Do not run the unit in the vicinity of areas where there is
the risk of explosion or fire.
- Refuelling must only be performed when the engine is off.
- The unit is grounded using an adequate diameter copper
cable.
PRECAUTION
When using the generator, bear in mind that in wet or
very damp places and in confined, conductive spaces
the following regulations must be complied with:
Chap. 11, sect. IV of CEI regulation 64-8.

3.2 Grounding the unit

For user safety the unit must always be grounded paying
particular attention to the section of the cable used.
Connect the ground cable with the special terminal
located on the outlet panel (Fig.3 Ref.1). Make ground
connections following the table indicating the cable sec-
tions to be used; these depend on the power rating of the
generator:
Power KVA 10÷20 20÷40 40÷60 60÷80 80÷100
Section mm² 10 20 30 40

4 USING THE GENERATOR

4.1 Preliminary checks

The first time the unit is started up after maintenance, a
good rule of thumb is always to make certain that:
- the oil is at the required level. This is done using the dip
stick: see table for the suggested oils.
- the electrical devices are off so that the generator will not
start up under a load.
- the fuel pipes are in good condition and properly
connected.
- no electrical connections are in poor condition.

4.2 Start-up

Before starting up the generator, make certain that all
devices are off so as to prevent forcing the engine when it
is cold. Proceed with start-up by rotating the START key
(fig.6 ref. 7) clockwise one click. All the LEDs will light up
for approximately 2 seconds as the self-check is per-
formed. The battery recharge LED (fig.6 ref. 17) and the
low oil pressure LED (fig.6 ref.15) will then remain on.
Start up the unit by turning the ignition key clockwise all
the way; only release it when the engine has cut in.
However, in no case should the key be held down for more
than 5 seconds in an attempt to start up the engine.
All protections cut in 15 sec. after the unit is started up
and, in case of malfunction, the unit will shut down and a
warning light will go on indicating the malfunction.
Before turning on any of the devices, leave the engine
running without any load for at least five minutes. This will
allow it to reach operating temperature gradually thus
ensuring maximum engine life and preventing seizing.
4.3 Shut down
The unit is shut down by turning the ignition key (fig.6 ref.
7) all the way counter-clockwise.
Before shutting down the unit, it is advisable to let it run
for a few minutes without any load thus lowering the
temperature inside the engine and the alternator.

4.4 Hook up to the automatic control panel

The MPX series units are prepared for connection to an
automatic control panel able to automatically start up the
generator, to switch lines when line power cuts out and
switch back when the line voltage is returned.
In addition, the automatic control panel maintains the
charge in the generator start-up battery, even when the
generator is off.
The unit is hooked up to the automatic control panel
through the 6-pin connector found on the unit instrument
panel (fig.6 ref. 13) and a power supply plug inserted in the
outlet located on the generator instrument panel (fig.6 ref.
50
11).
