ETI NETCOM ADH Assembly Replacement Procedure page 2

MODEL ADH
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.
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.
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.
