The rating plate is located on the bottom of the hob. A copy is attached on the back cover of this book. The hob is supplied with a 3 core flexible supply cord incorporating a 3amp plug fitted. In the event of having to change the fuse, a 3amp ASTA approved (BS 1362) fuse must be used. Should the plug need to be replaced for any reason, the wires in the mains lead are coloured in accordance with the following code: Green and Yellow - Earth Blue - Neutral Brown - Live 1) Connect the green and yellow . (earth) wire to the terminal in the plug which is marked with the letter 'E' or the earth symbol or coloured green and yellow. 2) Connect the blue (neutral) wire to the terminal in the plug which is marked with the letter 'N' or coloured black. 3) Connect the brown (live) wire to the terminal in the plug which is marked with the letter 'L' or coloured red. Upon completion there must be no cut, or stray strands of wire present and the cord clamp must be secure over the outer sheath. In the event of having to change the fuse, a 3amp ASTA approved (BS 1362) fuse must be used. FO 0390 A cut off plug inserted into a 13 amp socket is a serious safety (shock) hazard. Ensure that the cut off plug is disposed of safely. Permanent Connection In the case of a permanent connection, it is necessary that you install a double pole switch between the hob and the electricity supply (mains), with a minimum gap of 3 mm. between the switch contacts and of a type suitable for the required load in compliance with the current electric regulations. The switch must not break the yellow and green earth cable at any point. Ensure that the hob supply cord does not come into contact with surfaces with temperatures higher than 50 deg. C. Replacement of the cable The connection of the voltage cable to the appliance's terminal block is of type "Y". This means that its replacement requires the specific equipment of a technician. In this case, only cable type H05RR-F must be used. The cable section must be suitable to the voltage and the working temperature. The yellow/green earth wire must be approximately 2 cm. longer than the phase wires. Wiring diagram 2 1 L N0 220 240 1 2 3 4 5 N 1. TAPS IGNITOR SWITCHES 2.

EARTH CONTINUITY CHECK Appliance must be electrically disconnected - meter set on W (Ohms) x 1 scale and adjust zero if necessary. — Test leads from any appliance earth point to earth pin on plug. Resistance should be less than 0.1 W (Ohm), check all earth wires for continuity and all contacts are clean and tight. B. INSULATION CHECK Appliance electrically disconnected, all switches ON. a) meter set on W (Ohms) x 1 scale. Test leads from L to N in appliance terminal block. If meter reads «0» then there is a short circuit. b) meter set on W (Ohm) x 100 scale. Repeat test with leads from L to E. If meter reads less than . (infinity) there is a fault. NOTE - Should it be found that the fuse has failed but no fault is indicated a detailed continuity check (i.e. by disconnecting and checking each component) is required to trace the faulty component. It is possible that a fault could occur as a result of local burning/arcing but no fault could be found under test. However a detailed visual inspection should reveal evidence of burning around the fault.
