5.5 Alarm Module (Option AM2)
WARNING
If the stainless steel enclosure is equipped with an alarm module (option AM2) or an integrated power supply
100 - 240 V AC (option AM3) and installation is not carried out correctly, there is the danger of a touch
voltage.
The HTS801's stainless steel enclosure must therefore be grounded during operation.
