5.1.   Mini-slots
Eaton 93PR has two Mini-slot communication expansion slots. The Mini-slots matching the UPS are as 
follows:
•  Gigabit Network Card
The second-generation Gigabit Network Card is the new generation network communication card for 
connecting the UPS with Ethernet and Internet. The new generation network communication card has 
many novel features. The remarkably increased network communication speed and the condentiality 
protocol can provide emergency power off, data saving and other services to authorized IT personnel.

•  Environmental Monitoring Probe generation 2 (EMPG2)
The second-generation ambient temperature probe used together with the “Gigabit Network Card” 
and “Industrial Gateway Card” supports series connection of four in a maximum length of 50 meters. 
Meanwhile, it also detects the ambient temperature and humidity. It can be easily mounted by magnets 
and provides 2 additional digital inputs. Warning limits for temperature and humidity can be congured in 
the network card and monitored in a real-time manner with Eaton’s IPM and IPP software. Temperature 
compensation for lead-acid battery can be achieved as well.
