Mounting
Mounting brackets are included with the H7AN. Use these brackets to mount the H7AN securely so that there is no play.
Installation
■ Terminal Arrangement
■ Connections
Solid-state Inputs (NPN Transistors)
The CP1, CP2, and reset inputs of the H7AN must be voltage inputs.
Turn the screws on the mounting
brackets counterclockwise to
loosen them sufficiently. Attach
the bottom mounting bracket first.
