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

orange

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.

Figure 2. THE POWER FILTER 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.

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.

step 4. If it was placed upside down

on the lid of the unit during this

procedure, carefully turn the cover

back over and work it back into

position, past the wires and other

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

cable goes into which receptacle.
