SIREC D Manual
POWER INPUTS
WARNING
Introduction
The mains voltage is connected via an
appliance plug whose PE conductor is connected
to the housing.
The appliance plug must be readily accessible
and is used to isolate the recorder
from the power supply.
SIGNAL INPUTS
WARNING
Use extreme caution when wiring signal input
connections. Hazardous potentials may
exist on signal input terminals, which are
floating, with respect to instrument ground.
These hazardous potentials may be exposed
inside the instrument case and on
the Rear Terminal Panel of your instrument.
Any voltage potential at the signal source
will exist on the instrument's respective signal
input terminal; e.g. power generator
stator winding temperature monitoring
thermocouples.
CONTACT OUTPUT TERMINALS
WARNING
Use extreme caution when wiring contact
output connections. Hazardous potentials
may exist on contact output terminals,
which are floating, with respect to instrument
ground. These hazardous potentials
may be exposed inside the instrument case
and on the Rear Terminal Panel of your instrument.
Any voltage potentials at the
contact circuit will exist on the instrument's
respective contact output terminals; e.g.
line-powered circuits.
