2.0 Installation
CAUTION: When connecting battery power to the inverter, all
battery negative connections must be connected prior to the
battery positive connections. When removing battery power
from the inverter, the battery positive should be removed
before any battery negative connections are disconnected. This
is done to prevent any communication chips/lines from becom-
ing the DC return path to the battery – causing permanent
damage to all connected accessories on the network.
Summation: Always ensure all battery negative circuits are
connected before connecting or disconnecting battery positive.
2.2.1 Connecting the MagWeb Device to a Single Inverter
Use the supplied four-conductor communications cable to connect the
MagWeb device’s “TO INVERTER” port to the Magnum inverter’s “Remote”
port.
2.2.2 Connecting the MagWeb Device to a Single Inverter
and Remote Control
The MagWeb device, using the supplied cable, can be located near the remote
or near the inverter. To mount the MagWeb device near the inverter, route
the 6ft four-conductor remote cable from the inverter’s Remote port to the
MagWeb device’s TO INVERTER port. Use the longer 50ft cable — supplied
with the remote control — to route the MagWeb device’s TO REMOTE port to
the remote control. To mount the MagWeb device near the remote, swap the
6ft remote cable with the 50ft remote cable.
2.2.3 Connecting the MagWeb Device’s Antenna
Attach one of the supplied rubber duck antennas to the antenna port on top
of the MagWeb device. Tighten fi nger tight. In high vibration environments a
small amount of low strength thread locking compound may be used.
2.3 Setting Up the Wireless Gateway
Place the wireless gateway in a location that is dry and away from extreme
temperatures. Allow room to view the LEDs on both ends and to affi x the
Ethernet cable without any kinks or sharp bends. Unless the MagWeb device
will be located in the same room, you must keep the wireless gateway anten-
na outside of a metallic enclosure or compartment. For best range, the wire-
less gateway and antenna should be mounted clear of obstructions and as
high as possible.
CAUTION: Do not mount the wireless gateway in a closed
battery compartment, or in an area where water or any other
liquid can enter the device and cause shorting or corrosion.
This failure is not covered by the warranty.
2.3.1 Connecting the Wireless Gateway’s Antenna
Attach the remaining rubber duck antenna to the antenna port on the wire-
less gateway, and then tighten fi nger tight. In high vibration environments a
small amount of low strength thread lock may be used.
