Chapter 5: Expansion Box and Virtual Expansion Box Installation
IMPORTANT: The communication network must be installed in a daisy chain topology. Consult the
wiring diagrams to see the maximum cable distance according to the wire gauge.
NOTICE
The recommended installation wire gauge is 16 AWG (diameter of 1.29mm or
cross sectional area of 1.30mm
2
) for the power supply wires at a length of 150
meters (500 feet). The recommended installation wire gauge is 18 AWG
(diameter of 1.02mm or cross sectional area of 0.82mm
2
) for the communication
wires at a length of 1200 meters (4000 feet). The cable must be twisted pair and shielded.
WARNING
Installation must only be performed by qualified service personnel.
WARNING
Insulation on conductors must be rated for 600 Volts and 90°C (194°F).
NOTICE
For the small terminal blocks used for inputs and low voltage outputs, use a
tightening torque from 0.5N*m (4.43lbf*in) to 0.6 N*m (5.2lbf*in) to fasten a wire.
NOTICE
EDGE network cables have to use class 1 load type. AP/Cumberland
recommends using TC-ER cable type.
NOTICE
Refer to the Wiring Methods and Materials section from the National Electric
Code to use the correct wire for the installation.
NOTICE
TC-ER conductors in sizes 18 AWG and 16 AWG shall be type FFH-2, KF-2, KFF-
2, PAF, PAFF, PF, PFF, PGF, PGFF, PTF, PTFF, RFH-2, RFHH-2, RFHH-3, SF-2,
SFF-2, TF, TFF, TFFN, TFN, ZF, or ZFF. Conductor with other types and
thicknesses of insulation shall be listed for Class 1 load circuit use.
The communication network must be installed in a daisy chain topology. The order of the wires is
very important. At both ends of network, the End-of-Line must be activated. If the wiring can’t be
done in a single chain, you might need to deactivate the end-of-line (EOL) resistor to improve com-
munication. AP/Cumberland does not warranty the proper operation if the topology network is not
daisy chain.
