Install Modem Gateway with a GP1, DL6 or GP2 logger
Powering the modem when using GP1 or DL6 Loggers
Power to the modem is supplied via the cable harness in the
Modem Box. Power is brought to the DIN rail either directly from
the battery via a fuse or indirectly via the solar regulator charger.
From the DIN rail it connects to both the modem and to the
external 5-way GP1 network cable socket built into the side of the
Modem Box.
This means that the battery power is also accessible to any GP1
logger externally connected on the GP1 cabling network. If you
don’t want this to
happen, the wiring at the DIN rail can easily be
altered (see cable harness wiring scheme on page 28).
WARNING: Cover the solar panel when wiring up the system, as
it will be live.
