1. Battery environment, battery ground fault and generator supply detection port (J4)
The battery environment, battery ground fault and generator supply detection port is described in Table 3-3.
Table 3-3 Description of battery environment, battery ground fault and generator supply detection port
Position	Name	Description
J4.1	ENV3	Battery environment detection (NC)
J4.2	BtG	Battery ground fault detection (NC)
J4.3	GEN1，2	On generator (NO)
J4.4	＋12V	+12V power
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 1mm2 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.

		Table 3-4 Description of maintenance bypass cabinet port
Position	Name		Description
J26.1	T_IT*		Input transformer overtemperature (NC)
J26.2	AUX_I		(Reserved)
J26.3	＋12V		+12V power
			Power ground
J26.4	GND
J30.1	FUSE		(Reserved)
J30.2	F_FAN		Fan fail alarm (NC)
J30.3	T_OT*		Output transformer overtemperature (NC)
J30.4	AUX_O		(Reserved)

Note*: Must be configured by software before becoming active

Note

All auxiliary cables must be double insulated. Wire should be 0.5~1.5mm2 stranded.

Dry contact output port (X1)

There are three output dry contact relays at the X1 slot, see Figure 3-6 and Table 3-5.
