Document Part Number 24100

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.

POWER FILTER MODULE
REMOVAL AND REPLACEMENT
To replace the Power Filter Module (23563)
in an ADH NETCOM AC NEMA Automatic
Air Dehydrator, perform the steps below.
1. Shut off machine power by
unplugging the unit.
2. Open the two front door latches,
loosen the two captive screws in the
corners of the housing opposite the
hinges, then open the NEMA box.
Place an object underneath the door
once open to help support it during
this procedure.
3. Remove the orange Ethernet cable on
the left by disconnecting both ends,
then removing it. Set aside for re-use.
Remove the power cable connector
on the right by loosening the captive
screw on each end of the green
connector, then unplugging the
connector. Disconnect the ground
wire by loosening the ground wire
retaining screw, then carefully
removing the ground wire. Refer to
Figure 1.
Figure 1. DISCONNECTING THE ETHERNET
CABLE,
THE POWER CABLE CONNECTOR, AND
THE GROUND WIRE.
Disconnect
both ends,
then remove

ethernet cable.
Loosen both captive screws,
then disconnect connector.
Loosen
screw,
then
remove
ground
wire.
4. Remove and retain the four mounting
screws from the four corners of the
protective front cover, then slowly lift
the front cover, carefully flip it over,
then set it down, upside down, to rest
on the inside of the enclosure door.
Be careful as there are still many wires
connected between the enclosure
and the front cover and there isn’t a
lot of slack. Note that the two upper
front cover mounting screws are
located in plain sight in the top
corners of the front cover, while the
two lower front cover corner
mounting screws are located down in
the front “well” of the unit. Use a
long-handled screwdriver to remove
them.

5. Note how the five electrical leads are
connected to the existing Power Filter
Module, then use a needle nose pliers
to carefully disconnect the leads from
the module. The two leads on the
Load side connect to the green power
connector. The three leads on the
Line side connect to the power supply.
Of the two connector leads, the black
lead is the line and the white lead is
neutral. Of the three output leads, the
black lead is the line, the white lead is
neutral, and the green/yellow lead is
ground. All of these leads will connect
to the new module the same way.

The two leads on the
Load side connect to
the green power
connector.
The three leads on the
Line side connect to
the power supply.
6. Using the nut driver, remove and
retain the nuts and lock washers
securing the existing module to the
chassis. Once all five electrical leads
have been disconnected and the
mounting hardware has been
removed, remove the existing Power
Filter Module from the unit.
7. Position the new Power Filter Module
over the Pem
®
studs on which the
original module was installed. Using
the nuts and lock washers retained in
step 6, install the new Power Filter
Module and torque to 10 in/lb.
Connect the electrical leads in the
corresponding locations on the new
Power Filter Module from which they
were removed on the old module.
Refer to the following tables. Make
sure all leads are secure.

components in the enclosure.
Reinstall the four corner screws
securing the front cover to the
chassis.
13. Reconnect the ground wire by
inserting it behind the retaining
screw from which it was removed,
then tighten the ground wire
retaining screw. Reconnect the green
power connector by holding it in
place then tightening the two captive
screws removed in step 3. Reconnect
both ends of the orange ethernet
cable removed in step 3. It does not
matter which end of the ethernet
