72-6696 Spectrum Analyzer

FOR UNITED KINGDOM ONLY

NOTE: This lead / appliance must only be wired by competent persons

WARNING: THIS APPLIANCE MUST BE EARTHED

IMPORTANT: The wires in this lead are coloured in accordance with the following code:

Green/ Yellow: Earth Blue: Neutral Brown: Live (Phase)

As the colours of the wires in main leads may not correspond with the colours marking identified in your plug/appliance, proceed as follows:

The wire which is coloured Green & Yellow must be connected to the Earth terminal marked with the letter E or by the earth symbol or coloured Green or

Green & Yellow. The wire which is coloured Blue must be connected to the terminal which is

marked with the letter N or coloured Blue or Black. The wire which is coloured Brown must be connected to the terminal marked with

the letter L or P or coloured Brown or Red. If in doubt, consult the instructions provided with the equipment or contact the

supplier. This cable/appliance should be protected by a suitably rated and approved HBC

mains fuse: refer to the rating information on the equipment and/or user instructions for details. As a guide, cable of 0.75mm2 should be protected by a 3A or 5A fuse. Larger conductors would normally require 13A types, depending on the connection method used. Any moulded mains connector that requires removal /replacement must be destroyed by removal of any fuse & fuse carrier and disposed of immediately, as a plug with bared wires is hazardous if a engaged in live socket. Any re-wiring must be carried out in accordance with the information detailed on this lable.

1) Disassembly of the Instrument

• Do not disassemble the instrument; refer the instrument to a factory approved service facility only.

2) AC Power Input

CAUTION

• AC input should be within the range of selected line voltage +/- 10%.

• Insure the correct fuse is installed prior to applying voltage for the first time -

90 V ~ 132 VAC input : T 1A / 250V

198 ~ 250 VAC input : T0.5A / 250V

• Check the line voltage setting on the rear panel. If the line voltage does not match input voltage, change as follows:

a) Remove AC Power Cord; b) Open cover of AC socket with flat blade screwdriver; c) Remove selector Cam Drum and rotate to the correct voltage selection d) Replace Cam Drum.

3) Grounding

WARNING

• To avoid electrical shock, the power cord protective grounding conductor must be connected to earth ground.

4) Fuse Replacement

WARNING

• For continued fire protection, replace the fuse with the specified type and rating only.

• Disconnect power cord before replacing fuse.

• If the fuse is blown, there is something wrong with the instrument. Repair the

cause of fault before replacing fuse.

5) Cleaning

• Disconnect AC Power Cord from the instrument before cleaning.

• Use a soft cloth dampened in a solution of mild detergent and water. Do not

spray any liquid into the unit.

• Do not use chemicals or cleaners containing benzene, toluene, xylene, acetone or other harsh chemicals.
