The NetMan environmental sensors monitor and record environmental conditions in the area where the UPS is installed. The environmental sensors allow management and control to be extended to cover the area around the UPS, monitoring the temperature and humidity and driving cooling fans or locks. Values are provided via Internet, SNMP and via PowerShield 3 software. PowerShield 3 can be used to manage sensor operating states in order to send messages. Refer to PowerShield 3 software documentation for further information. NetMan can manage as many as 6 separate sensors. Environmental sensors are quick to install thanks to their small footprint, and they do not require a separate external power supply. The configuration is also rapid and intuitive due to self-learning sensors.
