Output Current Display (SB3024DiL only)

The display can show total output current from all networked controllers, or the output current of a single controller. To show
output current from a single controller IPN network address of the display and charge controller must match.

BATTERY AND PV WIRING
¾
CAUTION: Battery and PV compression terminals accept #14
−4 AWG wire and are tightened to 45 in-lb (5 nm). IPN network
compression terminals accept #24
−14 AWG wire and are tightened to 2.1 in-lb (0.24 nm). Auxiliary Output compression
terminals accept #24
−12 AWG wire and are tightened to 6 in-lb (0.67 nm).
¾
CAUTION: DO NOT connect Bat– and PV– together external to the 3024 or improper operation will result. Bat– and PV–
connect together internally.
A desirable installation would produce a total system wiring voltage drop of 3% or less. The lengths shown in Table 2 are one way from the PV to the battery
with the 3024 located along the path. Wire length can be increased inversely proportional to actual current. If current was reduced by ½, wire lengths could doubled
and still provide 3% voltage drop.

TABLE 2
ELECTROMAGNETIC COMPATIBILITY
To comply with electromagnetic compatibility requirements the 3024’s battery and PV wiring must be installed in grounded metallic conduit, and the two
clamp on type ferrite suppressors supplied must be installed. Clamp one suppressor around both Bat+ and Bat– cables. Clamp the second suppressor around
both the battery temperature sensor and remote display cables with the cables looped to pass through the core 3 times. If both sensor and display cables are
used, the sensor cable outer cover must be stripped back
≈12” (30cm) so both cables will fit through the core 3 times. Ensure that the two suppressors are
restrained so they will not damage circuit board components. Additional suppressors can be ordered as BSE p/n 523-0005-01.
BATTERY TEMPERATURE SENSOR
Installation of the optional battery temperature sensor enables temperature compensation of all charge voltage setpoints. In a multi-controller system a
single temperature sensor must connect to the IPN master. Do not attach a sensor or connections other than Blue Sky Energy battery temperature sensor p/n
930-0022-20. Be certain to observe proper RED/BLK polarity.
AUXILIARY OUTPUT
The auxiliary output can serve one of three functions; a 2A auxiliary battery charger, a 20A load controller with Low Voltage Disconnect (LVD), or a 20A
variable Dusk-to-Dawn lighting load controller. The Charge/Load function is selected by DIP switch #4 shown in Figure 3. The IPN-ProRemote is required to adjust
LVD thresholds or enable Dusk-to-Dawn lighting control. Auxiliary outputs in a multi-controller system will function normally, but only the auxiliary output in the
master can be configured or monitored using the IPN-ProRemote. The auxiliary output “Load” LED will illuminate whenever the auxiliary output is ON.
¾
CAUTION: The auxiliary output cannot perform both auxiliary battery charge and load control functions at the same time. Do not
connect to the 20A Load terminal for auxiliary battery charge.
