FLEXmax 80 Wiring Connections | Outback Power Systems specification

3. FLEXmax 80 Wiring Connections

Figure 1 FLEXmax 80 wiring compartment

Use up to 2 AWG (33.6 mm2) wire and torque to

35-inch pounds at terminals.

MATE/HUB

RJ45 jack

Battery Remote Temp Sensor (RTS) RJ11 jack

Programmable AUX Output Jack (supplies up to 200mA @ 12 VDC

PV+ PV- BAT- BAT+

Wire Lugs

Chassis/Equipment

Ground Lug

Screw holes for attaching FLEXmax 80

The PV (-) and BAT (-) terminals are connected internally. Only one negative wire may be needed to connect to the (-) wire lugs if the PV - and BAT- conductors are bonded at the negative bus bar. See Figures 2 and 3 for sample wiring diagrams. See Wire and Disconnect Sizing on page 80 for suitable conductor/wire sizing.

NOTES:

•Each FLEXmax 80 requires its own PV array. DO NOT PARALLEL FLEXmax 80 PV+ and PV- TERMINALS ON THE SAME ARRAY!

•An optional battery Remote Temperature Sensor (RTS) is recommended for accurate battery recharging (only one RTS is needed for multiple OutBack Series Inverter/Chargers and FLEXmax 80 units when an OutBack HUB and a MATE are parts of the system). When one RTS is used, it must be connected to the component plugged into the Port 1 of the HUB.
