WARNINGS
® Disconnect the mains plug from the supply socket when not in use.
¢@ This equipment is not designed for connection to an IT power system.
@Care must be iaken to ensure that the integrity of the PELV (Protective Extra Low Voltage) system is maintained
when interface to other parts of equipment takes place.
This apparatus must be earthed for your safety.
To ensure safe operation three pin-piug (not for U.K.) must be inserted only into a standard tree-pin power point which
is effectively earthed through the normal household wiring.
Ensure the main outlet socket is easily accessible to enable the user to isolate the apparatus from the main supply by
withdrawing the main plug.
Extension cords used with the equipment must be three core and be correctly wired to provide connection to. earth.
Wrongly wired extension cords are major cause of fatalities.
The fact that the equipment operates satisfactorily does not imply that the power point is earthed and that the
installation is completely safe.
For your safety, if any doubt about the effective earthing of the power point, consult a qualified electrician.
IMPORTANT
The wires in this mains lead are coloured in accordance with the following code:
Green-and-Yellow: Earth
Blue: Neutral
Brown: Live
As the colours of the wires in the mains lead of this apparatus may not correspond with the coloured marking
identifying the terminals in your plug, produced as follows: The wire which is coloured GREEN-and-YELLOW must be
connected to the terminal in the plug which is marked by the letter E or by the safety earth symbol or coloured GREEN
of GREEN-and-YELLOW.
The wire which is coloured BLUE must be connected to the terminal which is marked with the letter N or coloured
BLACK.
The wire which is coloured BROWN must be connecied to the termina! which is marked with the letter L or coloured
RED.
