FH-L, FH-M, AND FH-S ENCLOSURES
For FH-L or FH-M Series, you can connect the 24 VAC wires to either of the power connector wires.
For the FH-S Series, you must observe polarity by connecting the neutral wire to the unit’s neutral connector (black wire) and the hot wire to the
unit’s hot wire connector (red wire). Failure to observe wiring polarity might cause damage to the system.

WARNING: The FH-S Series is powered by 12 VDC only. Applying high voltage directly to the FH-S Series will damage the housing, void
the warranty, and create an electrocution hazard that can be harmful or fatal. Do not begin wiring until you have fully read and understand
these installation instructions.
