THIS INSTRUMENT MUST BE EARTHED
All models are supplied with two mains leads
fitted with IEC plugs for connection to the
instrument. One has a U.K. 3 pin plug and the
other has a 2 pin “Schuko” plug for connection
to the mains. Choose the lead appropriate for
your electrical installation and discard the other.
Should neither lead be suitable, take the lead
with the U.K. plug and replace the plug with a
suitable alternative. This involves cutting off the
moulded plug, preparing the cable and
connecting to the rewireable plug in accordance
with its instructions.
IT IS IMPORTANT THAT THIS OPERATION
SHOULD ONLY BE UNDERTAKEN BY A
QUALIFIED ELECTRICIAN
NOTE: Refer to the equipment’s rating plate to
ensure that the plug and fusing are suitable for
the voltage and wattage stated.
The wires in the mains cable are coloured as
follows:
BROWN - LIVE
BLUE - NEUTRAL
GREEN/YELLOW - EARTH
The instruments are fitted with an IEC socket at
the rear of the instrument for connection of the
mains lead. The appropriate mains lead should be
connected BEFORE connection to the mains
supply.
Should the mains lead need replacement a cable
of 1mm
2
of harmonised code H05W-F connected
to an IEC320 plug should be used.
N.B. The UK mains lead is protected by a 10A
fuse mounted in the plug top.
IF IN DOUBT CONSULT A QUALIFIED
ELECTRICIAN
When connected to the mains electricity supply a
green light on the front panel illuminates, except
for the digital SD300 and SD500 models where
the display will illuminate showing the word
“OFF”.
