Power/Ethernet Module
A GridMaster Microgrid Control System comes standard
with a Power/Ethernet Module that provides connections
for power, an intruder detection switch, Ethernet
communications, and a coaxial port for connecting a GPS
antenna. See Figure 3. The Door Intrusion feature will be
explained in the “Installing Enclosure Intrusion Detection”
section on page 13. Pinouts are shown in the “Module
Pinouts” section starting on page 15.
Complete the following steps to connect to the Power/
Ethernet Module:
STEP 1.
If present, connect the IED’s GPS antenna to the
female coaxial connector on the controller.
STEP 2.
Connect a solid-copper Ethernet cable to the
Ethernet 0 port on the controller. The other end
of the cable may be connected to either a radio,
a network switch, or directly to the local-area
network on which the GridMaster Microgrid
Control System will be interconnected.
STEP 3.
The GridMaster controller can accept control
power between 9 and 36 Vdc. Connect the two
12 –30 AWG wires from the control power source
to the GridMaster controller to the first two
(left-hand facing) screw terminals. Input power
must be 9 to 36 Vdc.
S&C recommends the control power source
be supported by a uninterruptable power supply
that can power the controller for at least one hour
after control power is lost.
STEP 4.
If the associated IED communicates via
Ethernet, connect a solid-copper Ethernet cable
to the Ethernet 1 port. Connect the other end to
the IED according to the IED manufacturer’s
instructions.
