5.4 ARC Module (Option AM1)
Please refer to chapter 3.5.3. ARC Module (Option AM1).
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.
For the contact scheme in standard and inverted operation mode, please refer to Tab. 4 in chapter 5.1 Electrical
Connection and Wiring Overview.
