3.6.8.7 ENVIRONMENTAL
Humidity: max. 95%, not condensing
Operating temperature: -20°C ... +70°C
Storage temperature: -40°C ... +85°C
At pollution level 2 the Slave may be operated up to 650V
At pollution level 3 the Slave must not be operated
At applications above 650 VDC non-conducting screws have to be used fixing the module
mechanically
Environmental tests:
 Temperature Test ISO16750-4:
o at – 40 °C
o 96 h at +85 °C
o 4 x cycle with -40°C und 85°C
 Insulation test: 300GΩ / 5kV DC
 EMC: EN 55022 and EN 55024 (industrial environment)
3.6.9. PASSIVE CELL BALANCE
Depending on the cell voltage, there are various slave 6 A module. The types are shown in
