Installation
2.4 Communications Cables – Provided
With the purchase of the ME-RTR router, Magnum has included four six-foot, yellow communication
cables. These cables—shown below—are provided to make connections between the router and
your Magnum inverter easier and code compliant. Two of the communications cables are remote
(RJ14) cables, two are parallel stack (RJ45) cables.
Most of the systems that use the router will also use an enclosure that includes the components
required in a parallel inverter system (i.e., Magnum’s 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 Magnum 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 Magnum’s
networked accessories (i.e., ME-AGS-N, ME-BMK). If stacking inverters on Magnum’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.
