protective earthing ground incorporated in the power cord). The
mains plug shall only be inserted in a socket outlet provided with a
protective earth contact. Any interruption of the protective
conductor inside or outside of the product is likely to make the
product dangerous. Intentional interruption is prohibited.
Whenever
it
is likely that the protection has been impaired, the
instrument must be made inoperative and be secured against any
unintended operation.
If this instrument is to be energized via an auto transformer (for
voltage reduction), make sure the common terminal is connected to
the earth terminal o f the power source.
If this product is not used as specified, the protection provided by
the equipment could be impaired. This product must be used in a
normal condition (in which all means for protection are intact) only.
No
operator serviceable parts in this product. Refer servicing to
qualified personnel.
To
prevent electrical shock, do not remove
covers.
Servicing instructions are for use by qualified personnel only.
To
avoid electrical shock, do not perform any servicing unless you are
qualified to do so.
The opening of covers or removal of parts is likely to expose
dangerous voltages. Disconnect the product from
all
voltage sources
while it is being opened.
The power cord is connected to internal capacitors that my remain
live for 5
seconds after disconnecting the plug from its power supply.
For Continued protection against fire hazard, replace the line fuse(s)
only with
250
V
fuse(s) or the same current rating and type (for
example, normal blow or time delay). Do not use repaired fuses or
short circuited fuseholders.
Always use the three-prong ac power cord supplied with this
product. Failure to ensure adequate earth grounding by not using
this cord may cause product damage.
This product is designed for use in Installation Category 1 1 and
Pollution Degree 2
per IEC 1010 and
IEC
664
respectively. FOR
INDOOR
