Integrated Power Supply 100 - 240 V AC (Option AM3)
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.

WARNING
Non-compliance to the following instructions can cause an electrict stroke with the risk of serous injury or death.
▪.
The AM3 option includes a 1.25 A fuse on the 100 - 240 V side. This fuse may not be replaced by the
user, only by the E+E after sales service.
▪.
The protection of the supply cable against excess current and short-circuit must be designated to a wire
cross section of 0.8 mm
2
(AWG 18) (6A fuse).
▪.
The metal enclosure must be grounded during operation.
▪.
All national regulations for installation shall be observed!
NOTICE
External diameter of the supply cable for option AM3: 10...12 mm (0.39...0.47").
Maximum wire cross section for AM3 connecting cable: 1.5 mm
2
(AWG 16) .
External diameter of the cable for Modbus RTU and analogue output female plug: 4...6 mm (0.16...0.24").
Maximal wire cross section for connecting cable: 0.5 mm
2
(AWG 21).
