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

cross-section area for maximum runs between 25
and 50 meters, respectively.
2. Maintenance bypass cabinet port (J26, J30)
J26 and J30 are the maintenance bypass cabinet (MCB) port. The ports are described in Table 3-4.
