Connecting Solar Power

EXPLOSION HAZARD: Ensure the area in which you perform this operation is non-
hazardous. Performing this operation in a hazardous area could result in an explosion.
Restriction
The solar panel and lead acid battery combination cannot be used with ATEX/IECEx
applications.
When power comes from a solar panel/lead acid battery combination, connect using the
BATT+ and BATT– terminals and standard copper wire (#18 AWG minimum).
Important
Only use batteries supplied with the flow computer or sold by Emerson as spare parts for
this flow computer. If you substitute a battery you obtain elsewhere you will void your
certification unless it is the identical part from the same manufacturer as that supplied
with the flow computer from Emerson.
Important
If you purchase a solar panel/external solar regulator combination other than the
Emerson-approved option, it must meet the specifications listed in
2.10.3.1

Wiring the 30W Solar Panel

For the 30W solar panel option with an external solar controller (charger/regulator)
purchased through Emerson (Emerson-approved option) connect the external solar
controller to the flow computer battery using the instructions in this section.
If you are using your own external solar controller/30W solar panel not purchased
through Emersion, you can use this section as an example of a typical installation. You
should also consult the manufacturer's instructions for your solar panel/solar regulator.
In either situation, you must use the battery, cables, and fuses supplied by Emerson for
your connections to the solar controller/solar panel.
Note
When making connections to the junction box or the solar regulator, you will need a
suitable cable gland/grommet to prevent water ingress to the junction box.
