Addressing the Point Module
Each point module has an address key that provides
a unique address in the field panel. A smaller
address marker (Figure 4) also identifies the
termination block should the point module and
termination block become separated.
1. Unpack a set of address keys from the
shipping carton.
2. Match the last three digits of the point
module address number (for example,
00200012 shown on the point module label
with the corresponding address key number
(in this case 012).
3. Detach the appropriate address key from the
spine.
CAUTION:
The point address number on the front label
MUST be identical to the address key
number.
4. Insert the address key into the slot located
at the top right-hand corner of the point
module as shown in Figure 4.
5. Insert the smaller address marker to identify
which termination block is used with the
point module (Figure 4). If the point module
and termination block are separated,
compare the address key in the point
module to the address marker on the
termination block.
6. Repeat Steps 1 through 5 for each point
module being addressed.

Installing the Point Module
After labeling and addressing all PTMs, you can
begin the installation.
CAUTION:
Circuits powering PTM6.2Q250-M point
modules must be limited by a 15 amp (max.
)
circuit breaker.
NOTE:
The point module and termination block
contain mechanical keys that prevent the
assembly of a module and block of different
voltages. If the point module does not mount
easily to the termination block, do not use
force. Check if the point module and
termination block match. The High Voltage
block can be identified by the dark gray color
and the symbol
⊗
printed next to the
termination block part number.
Figure 5. Installing a Point Module.
1. Remove any Module Bus (M-Bus) protective
tape that was not already removed when the
termination blocks were wired.
2. Starting at the top left-hand side of the MBC
or RBC, install each point module in the
order shown on the layout sheet.
3. Insert the point module’s mounting guides
into the right-hand edge of the M-Bus rail as
shown in Figure 5.
4. Swing the free end of the point module down
so that it mates with the previously installed
and wired termination block. Verify that the
point module is aligned with the termination
block and firmly press the point module into
place.
NOTE:
You will hear a “click” when the point
module is properly mounted.
5. Repeat Steps 1 through 4 for each point
module being installed.
