Protect the power cord from being walked on or pinched particularly at plugs,
convenience receptacles, and the point where they exit from the apparatus.

Use only with the cart stand, tripod bracket, or table specified by the manufacture,
or sold with the apparatus.  When a cart is used, use caution when moving the
cart/apparatus combination to avoid injury from tip-over.

been dropped.

POWER ON/OFF SWITCH: For products provided with a power switch, the power
switch  DOES NOT break the connection from the mains.

MAINS DISCONNECT:  The plug shall remain readily operable.  For rack-mount or
installation where plug is not accessible, an all-pole mains switch with a contact
separation of at least 3 mm in each pole shall be incorporated into the electrical
installation of the rack or building.

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

MULTIPLE-INPUT VOLTAGE: This equipment may require the use of a different line
cord, attachment plug, or both, depending on the available power source at
installation. Connect this equipment only to the power source indicated on the
equipment rear panel. To reduce the risk of fire or electric shock, refer servicing
to qualified service personnel or equivalent.

This Equipment is intended for rack mount use 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 follows:

• 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 units 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.

The symbols shown above are internationally accepted
symbols that warn of potential hazards with electrical
products.

The lightning flash with arrowpoint in an

equilateral triangle means that there are dangerous
voltages present within the unit. The exclamation point in
an equilateral triangle indicates that it is necessary for the
user to refer to the owner’s manual.

These symbols warn that there are no user serviceable
parts inside the unit.

Do not open the unit.

Do not

attempt to service the unit yourself. Refer all servicing to
qualified personnel. Opening the chassis for any reason
will void the manufacturer’s warranty. Do not get the unit
wet. If liquid is spilled on the unit, shut it off immediately
and take it to a dealer for service. Disconnect the unit
during storms to prevent damage.
