Monarch Instrument DC 2000 - Manual (Page 15)

SAFETY NOTICE
This Safety Notice has been included to emphasize the danger of hazardous voltages on the REAR
TERMINAL PANEL of your instrument. USE EXTREME CAUTION WHEN INSTALLING OR
SERVICING your instrument. Please read the entire contents of the Installation and Wiring Chapter
before attempting to install or service your instrument.
WARNING
ELECTRIC SHOCK HAZARD
MAY CAUSE INJURY OR DEATH.
USE EXTREME CAUTION
WHEN INSTALLING OR SERVICING
REAR TERMINAL PANEL.
FOLLOW INSTRUCTIONS BELOW.
POWER INPUTS WARNING
When connecting power to the Rear Terminal Panel of your instrument, it is important to ensure that the
AC mains cable has an effective ground and provide a low impedance earth ground connection (Safety
Ground) to the screw terminal on the rear panel labeled “ “ or “GND” to prevent the possibility of
electrical shock. Power may be exposed on the Rear Terminal Panel and is exposed inside the
instrument case. When wiring, use the supplied AC mains cable or recommended plug, make sure the
HOT wire, or Line 1 is connected to L/H. Make sure the NEUTRAL wire, or Line 2, is connected to N, and
make sure a low impedance SAFETY GROUND wire is connected to “ “ or “GND”.
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.
