A two-pin socket accepting the power cable AN 0020 provided for con-
nection of the AC mains supply. Before connecting a supply, the mains
voltage setting and fuse checks given in section 3.1.3 should be car-
ried out to ensure safe operation of the instrument.
A pair of clamping terminals with captive link for connecting or dis-
connecting signal ground and chassis circuits of the instruments. If this
link is removed, the two ground circuits must be interconnected at
some other point in the instrumentation system. Refer to section 3.1.4
for further details of ground connections.
WARNING: The Vibration Exciter Control Type 1 050 is designed to be
operated with its Signal Ground
&
Chassis at earth potential. Never let
the signal ground terminals, socket screens or chassis float at other
than approximately zero earth potential, as this will impair the operat-
ing safety of the apparatus and may damage it.
