ELECTRICAL SHOCK HAZARD
Failure to follow these instructions may result in
serious personal injury, death, and/or property
damage.
Installation and repair of electrical generators
and voltage regulators should be attempted
by qualified personnel only. Electrical con-
nections shall be made by a qualified electri-
cian in accordance with all local, national,
international and/or other applicable codes,
rules or regulations and sound practices.
Do not touch electrically live parts.
Disconnect, lockout and tag prime mover
and input power supplies before installing or
servicing voltage regulator. Use a voltmeter
to verify that power is off before contacting
conductors.
Do not open terminal box or touch unpro-
tected terminals while the generator shaft
is rotating. Shaft rotation produces voltage
in generators even when no excitation is
applied. Residual voltage is present at the
generator leads and regulator connections
even when the regulator fuse is removed.
Ground (earth) regulator in accordance with
local, national, international and/or other
applicable codes, rules or regulations.
MAGNETIC FIELD HAZARD
Permanent magnet generator (PMG) rotors, when
removed from the stator, expose surrounding per-
sonnel and equipment to powerful magnetic fields
which may cause serious health hazards to persons
with pacemakers, hearing aids, or other implanted
electronic medical devices and may impact other
electronic devices such as mobile phones, credit
cards, etc.
EXPLOSION HAZARD
Beware of arcing when connecting test leads.
Arcing could spark an explosion if exposed to
battery gases, fuel vapors or other hazardous
atmospheres. Failure to follow these instructions
could result in serious personal injury, death and/
or property damage.
MECHANICAL SAFETY
ROTATING PARTS HAZARD
Keep extremities, hair, jewelry and clothing away
from moving parts. Failure to follow these instruc-
tions could result in serious personal injury, death
and/or property damage.
OVERSPEED HAZARD
Do not exceed the rated speed of the generator.
Excessive centrifugal forces could damage the
rotating fields and cause parts to be expelled at a
high rate of speed. Failure to follow these instruc-
tions could result in serious personal injury, death
and/or property damage.
DO NOT DISASSEMBLE
Only qualified personnel who know local, national,
international and/or other applicable codes, rules
or regulations and sound practices should install or
repair electric generators and voltage regulators.
Failure to follow these instructions could result
in serious personal injury, death and/or property
damage.
PREVENTATIVE MAINTENANCE
The only preventive maintenance required on the
DVR
®
is to periodically check that the connec-
tions between the DVR
®
and the system are clean
and tight. The only user serviceable part on the
DVR
®
is the fuse. Marathon Electric recommends
that no repair procedures, other than replacing the
fuse if needed, be attempted by anyone other than
Marathon Electric personnel.
