0.449 inch
* Some products are provided with strain reliefs. If the cable diameter goes over this diameter value, the strain reliefs may not
work properly.
WARNING
Insulation on conductors must be rated for 600 Volts and 90°C (194°F).
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.
AP/Cumberland can provide sourced color-coded communication wire to install EDGE controls. The wire
will be available in both 16 and 18 gauge to accommodate the specified distance between controls (as
shown above). The communication wire is available in one or two twisted shielded pairs, and with two dif-
ferent outside jacket colors (red and black.) Black-jacketed wire is to be used for the automation circuit
