Installation
Procedure (see Figure 29)
Take the end of the Z200A EMI filter cord that is closest to the
1.
filter and plug it into the SMDR port (the top one) on the
processor module.
Plug the other end of the EMI filter cord into a 355AF adapter.
2.
Connect the female connector on the 355AF adapter to one
3.
end of the EIA crossover cable. Connect the other end of the
EIA cable to the 25-pin male connector of a Z3A2 ADU.
CAUTION:
If the printer is in a building outside the main building (CU
location), an ADU and an additional protector must be
installed in each building. The ADUs and protectors provide
both the CU and the printer additional protection against
exposure to lightning, inadvertent contact with power lines,
and power currents induced by nearby power lines. See the
installation notes packed with the ADU for more information.
4. Plug one end of a D8W cord into the Z3A2 ADU and the other
end into an ADU crossover cable.
5. Plug the other end of the ADU crossover cable into one of the
jacks on a 400B2 power adapter.
6. Plug one end of a D6AP cord into the other jack of the 400B2
adapter. Plug the other end of the D6AP cord into the jack on
a 248B adapter (see Figure 30).
7.
Connect the spade-tip wires on the 248B adapter to the
screws on a 2012D transformer (see Figure 30).
Plug the 400B2 adapter into a BR1A-4P adapter, 102

connecting block, or 103 connecting block.
9. Place a plug onto the end of the inside wiring (DIW) on the
CU side and plug the DIW cord into the BR1A-4P adapter,
102 connecting block, or 103 connecting block.
