WARNING

FOR YOUR PROTECTION, PLEASE READ THE FOLLOWING:

WATER AND MOISTURE: Appliance should not be used near water (e.g. near a
bathtub, washbowl, kitchen sink, laundry tub, in a wet basement, or near a swimming
pool, etc).  Care should be taken so that objects do not fall and liquids are not spilled
into the enclosure through openings.

POWER SOURCES: The appliance should be connected to a power supply only of
the type described in the operating instructions or as marked on the appliance.

GROUNDING OR POLARIZATION: Precautions should be taken so that the ground-
ing or polarization means of an appliance is not defeated.

POWER CORD PROTECTION: Power supply cords should be routed so that they are
not likely to be walked on or pinched by items placed upon or against them, paying
particular attention to cords at plugs, convenience receptacles, and the point where
they exit from the appliance.

SERVICING: To reduce the risk of fire or electric shock, the user should not attempt to
service the appliance beyond that described in the operating instructions.  All other
servicing should be referred to qualified service personnel.

FOR UNITS EQUIPPED WITH EXTERNALLY ACCESSIBLE FUSE RECEPTACLE:
Replace fuse with same type and rating only.

SAFETY INSTRUCTIONS 

NOTICE FOR CUSTOMERS IF YOUR UNIT IS EQUIPPED WITH A POWER
CORD.

WARNING: THIS APPLIANCE MUST BE EARTHED.

The cores in the mains lead are coloured in accordance with the following code:

GREEN and YELLOW - Earth        BLUE - Neutral        BROWN - Live

As colours of the cores in the mains lead of this appliance may not correspond
with the coloured markings identifying the terminals in your plug, proceed as fol-
lows:

• The core which is coloured green and yellow must be connected to the

terminal in the plug marked with the letter E, or with the earth symbol, or
coloured green, or green and yellow.

• The core which is coloured blue must be connected to the terminal

marked N or coloured black.

• The core which is coloured brown must be connected to the terminal

marked L or coloured red.

This equipment may require the use of a different line cord, attachment plug, or
both, depending on the available power source at installation.  If the attachment
plug needs to be changed, refer servicing to qualified service personnel who
should refer to the table below.  The green/yellow wire shall be connected
directly to the unit's chassis. 

WARNING: If the ground is defeated, certain fault conditions in the unit or in the
system to which it is connected can result in full line voltage between chassis
and earth ground.  Severe injury or death can then result if the chassis and
earth ground are touched simultaneously.
