| Note (applications) | Fail-safe delay timer |
| Note (General) | Inductive loads (e.g. contactors, relays, etc.) are to be suppressed by means of a suitable circuit. |
| Note (Wiring diagram) | The wiring diagram is shown with guard doors closed and in de-energised condition. The ISD tables (Intergral System Diagnostics) for analysis of the fault indications and their causes are shown in the appendix.
