Document Part Number 24099

SAFETY INFORMATION AND WARNINGS
Abnormal Odor or Smoke
In the event of smoke or a burning or
abnormal odor, immediately interrupt
power to the ADH NETCOM with the
POWER switch at the rear of the unit,
unplug the unit, or turn off the circuit
breaker controlling the outlet. Note
that only the AC model of the ADH
NETCOM has an ON / OFF switch.
Lethal Voltages Present
Lethal voltages are present inside the
ADH NETCOM. Service should be
performed by qualified personnel
only. There are no user serviceable
components inside the chassis.
Pneumatics
Each of the air pumps inside the ADH
NETCOM automatic air dehydrator is
capable of generating as much as 24
psig (1,655mbar). Other attached dry
air sources may be capable of
generating even higher pressures.
Proper safety practice requires
treating all pneumatic components
with care. Always vent the system to
atmospheric pressure before servicing
pneumatic components.
Rack Mounting
Before and after rack mounting the
ADH NETCOM, ensure that the rack
is stable. Mounting of the ADH
NETCOM into a rack should be such
that a hazardous condition is not
created due to uneven mechanical
loading. Verify that adequate air
flow and power source capacity is
available to the unit. Ensure that the
ADH NETCOM maximum operating
temperature of 130°F (55°C) will not
be compromised by other
components in the rack. Ensure
reliable earthing of the ADH
NETCOM.
