There is an IEC socket at the rear on the left
hand side of the instrument for connection to
the mains supply, (see figure 1). The unit is
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
"Shuko" plug for connection to the mains
supply. Choose the lead appropriate for your
electrical installation and discard the other.
Should neither lead be suitable you should
obtain a moulded lead locally. If this is not
possible, take the lead with the U.K. plug and
replace the plug with a suitable alternative.
Should the mains lead require replacement a
cable of 1mm
2
of harmonised code H05V V-F
connected to an IEC 320 plug should be used.
N.B. The UK mains lead is protected by a 10A
fuse mounted in the plug top.
The mains lead should be connected to the
instrument BEFORE connection to the mains
supply.
