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

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

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 0.75mm Larger conductors would normally require 13A types, depending on the connection method used.

or coloured Green or Green & Yellow.

should be protected by a 3A or 5A fuse.

Page 41

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 an engaged in live socket. Any re-wiring must be carried out in accordance with the information detailed on this label.

WARNING: For continued fire protection, replace fuse only with the specific type and rating by

qualified personnel. Disconnect the power cord before replacing fuse.

Cleaning the Cabinet

Disconnect the AC power cord before cleaning the instrument. Use a soft cloth dampened in a solution of mild detergent and water. Do not spray cleaner directly onto the instrument, since it may

leak into the cabinet and cause damage. Do not use chemicals containing benzing, benzne, toluene, xylene, acetone, or similar solvents.
