Skid System Connections
Required field connections to place the 8300G into
operation are as follows:
1. Connect the solar panel cable to the system power
supply, SPS-12, figure 16* .
Note: the solar panel should be mounted free of obstruct-
ing shade and should be facing south in the northern
hemisphere or facing north in the southern hemisphere.
1a. *If your system was ordered with the optional
LPS-120/240 power supply, AC power should be
connected in accordance with explosion-proof code
via a termination junction box to be attached to the
conduit provided at the upper left side on the system
enclosure. The power requirement for 120VAC will
be 100 mA. The power requirement for 240VAC will
be 50 mA. These power inputs must be fused with a
maximum of 15A,
figure 17
,
refer to the Wiring
Control Document on page 116 in Appendix D .
2. Connect the flow signal device to the termination
board located in the system control enclosure via the
conduit hubs to the N-300G,
figure 18 , refer to the
Wiring Control Document on page 116 in Appendix D .
2a. If used, connect the optional Inhibit Input signal to
the termination board located in the system control
enclosure,
figure 18 , refer to the Wiring Control
Document on page 116 in Appendix D .
2b. If used, connect the RS-485 communication wiring
as required to the termination board located in the
system control enclosure,
figure 18 , refer to the
Wiring Control Document on page 116 in Appendix D .
