Fig 2-6 Dry contact interface and communication interface
The UPS accepts external signal from zero-voltage (dry) contacts connected through external dry
contact terminals produced and phoenix terminals that are in bypass module. Through software
programming, these signals become active when these contacts connect to +24V to ground.The cables
connected to DRY terminal must be separated from power cables. Moreover, these cables should be
double insulated with a typical 0.5 to 1.5 mm

2.6.1 Dry Contact Interface of Battery and Environmental Temperature Detection
(Optional)
cross-section area for a maximum connection length
between 25 and 50 meters.
The input dry contact J2 and J3 can detect the temperature of batteries and environment
respectively, which can be used in environment monitoring and battery temperature compensation 1.
J2 and J3 interfaces diagram are shown in fig 2-7, the description of interface is in table 2-2.
