NOTE: The self-test alarm and user-programmable alarm contacts are shown in the de-energized state (no
voltage applied). The self-test alarm contacts open after the M-2001 passes the self-test; the user-program-
mable alarm contacts close when an alarm is recognized.
8 WARNING: In no case should the line current circuit be interrupted with the regulator or transformer
energized.
Do not remove auxiliary current transformers without shorting the current inputs. Death or severe
electrical shock can occur.
