Powering the Field Station
4.1 Introduction
There are three options for powering the field station. All involve using a rechargeable lead acid
battery (12 volt, 12 Amp Hour) that is mounted inside the 6200 DCP (field station).
One option is to use the battery as the sole source of power. A fully charged battery lasts from a
few days to a few weeks, depending on the number and type of sensors and the mode and
frequency of communication. The battery is easy to remove, requiring no tools. Low batteries
may be recharged using a P/N 6254 Charger. One approach to powering would be to use two
batteries and periodically swap out one for the other, recharging the low battery at the Lab or
office.
A second option is to use AC power, which continuously recharges the battery. When you order
the AC Power Option, a power module is installed in the interface plate inside the enclosure.
The module contains a 3-prong male receptacle, voltage selector and fuse compartment. A
power cable (provided) plugs into the receptacle and is used in both setup and permanent
installation procedures to provide AC power. Predrilled holes in the bottom of the NEMA
enclosure are designed for use with standard conduit fittings. Cabling may be routed through ½”
conduit to interface the charging circuit with the AC power source.
A third option is to use a solar panel (10 watt rating) with the field station. This unit is designed
for use in a nominal 12 VDC system. The 6200 DCP uses the solar energy to power the board
and recharge the battery for continuous operation. A dedicated 2-conductor receptacle and plug
are installed inside the NEMA enclosure for easy access to connect the solar cable to the 6200
DCP. Cabling may be routed through conduit or a feed-through gland to interface the power
circuit with the solar panels.
4.2 General Wiring Information
WARNING!
Wiring should be performed by a qualified electrician.
Do not make connections while power is applied. Disconnect power before proceeding.
This part of the installation of the 6200 DCP will vary considerably depending on the installation
setup you have chosen. Refer to Appendix E if you have not determined your installation setup.
Refer to sections below for specific power options and read thoroughly all general wiring
instructions before proceeding with the installation.
