3.4.3 Signal Input Wiring
Hazardous potentials may exist on signal input terminals which are floating with respect
to case ground. These hazardous potentials may be on the rear terminal panel of your
instrument. Any voltage potential at the signal source will exist on the i
nstrument’s
respective signal input terminal (i.e. power generator stator winding). The analog inputs
can sustain up to 1500 Volts with respect to the chassis ground.
This instrument is intended for use in Measurment Category I
– CAT I. The maximum
voltage on the signal input terminals is not to exceed 30V - - - (Volts DC. ) The maximum
transient voltage is not to exceed 50V - - - .This equipment is not intended for use in
Measurement Categories II, III and IV.
The recorder accepts up to twelve direct inputs. Input connection is via plug in screw terminal connectors on
the rear panel. Inputs can be mixed in any combination of thermocouple, RTD, milliamps, millivolts, volts or
contact inputs. In addition, channels 1 and 6 (and optionally 7 and 12) can accept frequency inputs via an
additional terminal. There is a common ground lug marked with a
for connection of signal cable shields
or screens.
