2.4 Communications Cables – Provided
The ME-ARTR router comes with four six-foot, yellow communication cables. These cables—
shown below—are provided to make connections between the router and your inverter easier and
code compliant. Two of the communications cables are remote (RJ14) cables, and the other two
are parallel stack (RJ45) cables.
Most systems that use the router will also use an enclosure that includes the components required
in a parallel inverter system (i.e., Magnum Energy panels). The NEC/CEC requires the insulation
of all conductors inside the enclosure to be rated for the highest voltage present. The router is
designed to work with 120/240 VAC inverters, therefore, the voltage rating of the communications
cables inside the enclosure must be rated for 300 volts or higher to be code compliant. These
communications cables have 300-volt rated insulation, to meet NEC/CEC requirements DO NOT
substitute for the supplied cables—most cables do not have the properly rated insulation.
Info: These cables carry less than 30 volts and are thus considered a “limited energy
circuit”, which is normally not required to be installed in conduit.
Info: Additional stack cables are available with the purchase of a MPX Series enclosure.
Stack cables are not sold separately. If NEC/CEC requirements do not apply, a CAT 5
cable (RJ45/8P8C) can be used. However, this CAT 5 cable must be no longer than 6
feet—this ensures there is no communication issue as these cables transmit/receive
high speed data.
Figure 2-4 shows a ‘ REMOTE’ cable (two are
supplied). This cable is 6’ (1.83m), with a RJ14
6P4C (6-position/4-conductor) telephone-type
male connector and a blue REMOTE label on
each end. It comes with 300-volt rated, yellow
insulation. One end of this cable is connected to
one of the communication ports (P1-P6) on the
router (see Figure 2-6 or 2-7), and the other
end is connected to the inverter’s Remote port
(normally routed inside the MP enclosure) as
shown in Figure 2-10.

Figure 2-5 shows a ‘ STACK’ cable (two are
supplied). This cable is 6’ (1.83m), with a RJ45
8P8C (8-position/8-conductor) connector on
each end. It comes with 300-volt rated, yellow
insulation. One end of this cable is connected to
one of the stacking ports (MA-SL3) on the router
(see Figure 2-11), and the other end is connected
to the inverter’s Stack/Accessories port (normally
routed inside the MP enclosure) as shown in
Figure 2-10.
2.4.1 Network Cable
A network cable is not supplied with the router, but is included with the purchase of our networked
accessories (i.e., ME-AGS-N, ME-BMK). If stacking inverters on Magnum Energy’s MP Series
enclosures, the regular network cable must be replaced with a high voltage network cable, which
is included with the purchase of the MP Series enclosure. This cable has 300-volt rated yellow
insulation, is 6’ (1.83m) long, and has a RJ14 6P4C (6-position/4-conductor) telephone-type
male connector on each end. One end of this cable is connected to the accessory, and the other
end is connected to the router’s Comm port or the inverter’s Network port (see Figure 2-11). This
cable is wired similar to the remote cable, and can be substituted for the remote cable, if needed.
