WEB-300E, WEB-600E/U, CP-300E, CP-600E/U SERIES CONTROLLERS
Do not incinerate or mutilate the battery, as
this may cause it to burst or release toxic
If regulations specify returning the old battery to a
recycling center, but no acceptable recycling center can
be found, please return the old NiMH battery pack to
Tridium for proper disposal.
Servicing the controller may call for replacement parts.
There are three categories of parts:
• Non-replaceable Parts
• Standard Replacement Parts
• New Replacement Unit

New Replacement Unit
To replace an entire unit, order and install a new WEB/
CP-300E or WEB/CP-600E/U controller. If the faulty
controller is still in warranty, you can receive credit by
returning it. Be sure to contact the vendor for a return
authorization (RA) number before shipping an item for
return credit. See "Returning a Defective Unit" on
page 17, for more details.
NOTE: Before ordering a new controller, it is
strongly recommended that you contact your
normal technical support resource to elimi-
nate the possibility of a software issue or
Replacing the Controller Base
NOTE: Before handling circuit boards, discharge
any accumulated static by touching a nearby
earth ground. For details, see the "Static Dis-
charge Precautions" section on page 6.
To replace a controller with a new replacement unit,
proceed as follows:
REPLACING A WEB/CP-300E OR WEB/CP-600E/U
1. If possible, use the appropriate WEBs-AX software
tool to back up the controller's configuration to your
2. Remove power to the controller. The unit should
power down automatically. Wait for all LEDs to
NOTE: If IO accessory modules are installed, and
any I/O points have voltage, turn the devices
off or disconnect power to them.
Other than the parts listed in the replacement parts
sections, there are no serviceable components on the

The controller contains a non-user replaceable fuse,
soldered on the circuit board. This fuse provides
protection from internal shorts or connection to incorrect
power supplies. If the fuse circuitry is suspect, seek
technical support. See "Returning a Defective Unit" on
Standard Replacement Parts
Standard replacement parts are listed in Table 5, and can
be ordered from stock without restriction. Standard
replacement parts cannot be returned for credit and
should be disposed of in an appropriate manner.
3. Note positions of all communications and other wir-
ing cables going to the controller, as well as
installed accessory modules (if they must be
removed). If necessary, label connectors and
accessory modules to avoid mis-connection later,
after the controller is replaced.
4. Unplug all Ethernet, serial, LON, modem, and I/O
connectors from the controller.
5. If IO accessory modules are installed:
a. If DIN rail mounting with DIN end-clips was
used, you may be able to remove the DIN rail
end clip that secures the 600E controller end of
the assembly, and then slide the controller away
from the rest of the assembly. Then you can
remove the controller from the DIN rail (see Fig.
1 on page 4), leaving the mounting and wiring of
IO modules untouched.
In this case, after removing the controller from
the DIN rail, go to Step 6.
b. If tab (screw) mounting was used instead of DIN
rail mounting, or if a combination of DIN mount-
ing and tab screws was used (into the control-
ler's "accessory side" tab holes, see last page),
you will need to remove accessory modules
first, before removing the controller. In this case:
(1) Making a careful note of all wiring termina-
tions, unplug the I/O connector plugs and
earth ground wires from the installed IO
(2) Remove the installed accessory modules,
starting with the end module.
(3) Remove any screws fastening the controller,
and remove it (see Fig. 1).
6. Remove the cover of the old unit. See See "Remov-
ing and Replacing the Cover" on page 4. Note the
position of installed option cards, if any. You must
transfer them to the replacement controller.
7. Remove any option cards from the old controller
and install them into the replacement controller, if
applicable. See See "Installing an Option Card" on
page 6. for more details.
