Use green plugs on the right side of the InsulGard (Figure 1-6 and 1-8). The green plugs can be wired when the
InsulGard is not installed on its panel yet.
Relays "Warning" (Alarm 1) and relay "Alarm" (Alarm 2) close NO contacts if partial discharge level exceeds
predefined thresholds. Relay "Status" has NO contacts closed if InsulGard has AC power and works properly. If
InsulGard lost AC power or works not properly (has Error) its contacts position is shown on the label.
