Note:
1. Must be configured by configuration software before becoming active.
2. When activated, the charger current can be limited, through software, to a percentage of the full charger current (0~100%).
3. Activating this feature will limit the battery charging
The UPS accepts external signaling from voltage-free (dry) contacts connected to finger-proof, push-in terminal J4.
Subject to prior software programming, the signaling is accepted by the UPS when connection between the relevant
terminal and the +12V terminal of J4 is altered. Cables connected to J4 must be segregated from power circuits (for
screening purposes), double insulated and of a typical 0.5 to 1mm
