thermal actuators are used, the transformer must not
be located below the electronics due to heating
effects.
WARNING
Electrical Shock Hazard.
Mains power at terminal block can cause personal
injury or death. Excel 10 FCU Controllers must be
mounted inside their fan coil unit boxes to prevent
access by unauthorized personnel.
To reduce the risk of fire or electric shock, install in a
controlled environment relatively free of contaminants.
