17 G20, 30, 40 SIIIA Operation & Maintenance Manual
WARNING
Electrical Shock -
Do not operate electrical equipment while standing in
water, on wet earth or with wet hands or shoes.
Use extreme caution when working on electrical
components. Battery voltage (12V / 24V DC) is
present unless the battery cables have been
disconnected. Higher voltage (potentially 480V) is
possibly present at all times.
WARNING
Always treat electrical circuits as if they were
energised.
Disable Start Control before attempting any repair
service, disconnect all leads to electrical power
requirements and disconnect battery to prevent start
up.
EARTHING
Comply with applicable electrical codes.
WARNING
The Generator Set can produce high voltages, which
can cause severe injury or death to personnel and
damage to equipment. The Generator Set should
have proper internal and external earth when
required by IEC 364-4-41.
The Generator Set is internally earthed neutral to the
frame of the Generator Set. This internal earth
connection is essential for proper Generator Set
performance and personal protection.
External earthing consists of connecting the
generator neutral to a solid earth, and is the
responsibility of the operator, when earthing is
required by IEC 364-4-41 Protection Against Electric
Shock, and other local codes as applicable.
Several methods are employed to externally earth
portable generator sets, depending on the intended
use and code requirements. In all cases, a
continuous length of splice-free copper cable, no
smaller than 10 mm
2
, shall be used for the external
earth conductor, when earthing is required.
A qualified, licensed electrical contractor,
knowledgeable in local codes, should be consulted.
WARNING
Failure to properly earth the Generator Set can result
in severe injury or death.
IF USED AS ALTERNATE POWER SUPPLY
Connect only after the main service entrance switch
has been DISCONNECTED and LOCKED OPEN.
In addition, circuit overload protection must be
provided in accordance with National Electrical
Codes and local regulations.
CAUTION
Welding -
Prior to any welding, disconnect alternator relays,
diagnostic circuit board, voltage regulator circuit
board, meters, circuit breakers and battery cables.
Open all circuit breakers, and remove any external
connections (except earthing rod). Connect the
welding earth as close as possible to the area being
welded.
WARNING
Electrical Loading -
Never make electrical connections with the unit
running.
Before placing the unit in operation, verify the
electrical rating of the Generator Set and do not
exceed generator set ratings.
