Figure 6-3 Starting and monitoring the forced checking procedure (test stop)
If the inverter outputs alarm A01699 or A01697, you must initiate a forced checking procedure
at the next opportunity, e.g.:
● When the system is switched on.
● At specified regular intervals before the monitoring time expires.
