New Replacement Units

To replace a faulty unit, order and install a

new

EC-BOS-6

—please note that EC-BOS

series products do

not

have special “field replacement units,” or FRUs, with separate part numbers.

If the faulty EC-BOS-6

still in warranty

, you can receive credit by returning it to Distech Controls. Be sure

to contact Distech Controls for a return authorization (RMA) number before shipping an item for return credit.
See

“Federal Communications Commission (FCC),”

page 24, for more details.

Note

Before ordering a new EC-BOS-6

, it is strongly recommended that you contact your normal technical

support resource to eliminate the possibility of a software issue or mis-configuration problem.

Replacing the base assembly

Caution

Before handling circuit boards, discharge any accumulated static by touching the metal surface of
the EC-BOS-6

. For details, see the

“Static Discharge Precautions”

section on page 4.

To replace the EC-BOS-6

base assembly in the field, proceed as follows:

Procedure 6

Replacing a EC-BOS-6

base assembly.

Step 1

Using the appropriate Niagara

software tool, back up the EC-BOS

’s configuration to your PC.

Step 2

Remove power to the EC-BOS-6

. The unit should power down automatically.

Note

If I/O accessory modules are installed and any I/O points have voltage, turn the devices off or
disconnect power to them.

Step 3

Note positions of all communications and other wiring cables going to the EC-BOS-6

, as well as all

installed accessory modules (if they must be removed). If necessary, label connectors and accessory
modules to avoid mis-connection later, after EC-BOS-6

is replaced.
