CAUTION: On the Conext Mini PDP, an additional circuit breaker will need to be installed. The Generator will connect through this circuit breaker and to the XW Pro or XW+ 6848 inverter.
Figure 8.0 – Optional Generator Installation/Connection Diagram Inverter Charger Grounding The Conext XW Pro or XW+ is provided with ground terminals that must be reliably connected to ground (protective earth) by appropriately sized equipment grounding conductors. System grounding for the AC and DC systems must be done according to all applicable NEC and local installation codes.
4.5.3 – AC System Bonding Multiple AC Neutral-to-Ground Bonds Verify that only one neutral-to-ground bond exists in the system. Having more than one neutralto-ground bond in a system violates local electrical codes, may create a shock or fire hazard, and may cause some sensitive equipment to malfunction. Failure to follow these instructions can result in death or serious injury and will void the Warranty.
Figure 9.0 – PV Array Connection Points AccESS DC Grounding To connect the Conext XW Pro or XW+ to the DC grounding system, use the ground lug at the bottom of the Conext XW Pro or XW+ chassis. The terminal accepts wires from #14 AWG (1.63 mm) to #2 AWG (6.54 mm). System grounding for the DC system, which typically involves bonding (connecting) the PHI 3.8 Battery negative circuit to ground, is dependent on the system configuration.
Figure 10.0 – Inverter Power-Up Standby Display Step 3: Enable the Inverter Invert mode is enabled by default, and the Conext XW Pro or XW+ should begin inverting upon transitioning from standby mode. If invert mode is disabled, the inverter information panel will display "- - -" once out of standby mode, as shown below. If the Conext XW Pro or XW+ powers up in standby mode, press the STARTUP/ SHUTDOWN button momentarily to change the mode from standby to operating. Figure 11.
Figure 12.0 – Inverter Enabled Display To disable the inverter: On the inverter information panel, simultaneously press the STARTUP/ SHUTDOWN button and the Equalize button. The Conext XW Pro or XW+ is now disabled, and “diS” (disabled) is briefly displayed on the inverter information panel, followed by "- - -". Figure 13.0 – Inverter Disabled Display Monitor the invert (green kW) LED to confirm which mode the inverter is in: • kW LED OFF – Invert mode is disabled.
• kW LED ON – The inverter/charger is on. The inverter is operating and is able to provide power to the AC loads. This is the default mode on initial power-up once the unit is taken out of standby mode. If the inverter is not operating or the inverter LED (kW) does not turn on, check all connections. Check the inverter’s DC voltage and polarity on the positive (+) and negative (–) terminals. Check the Fault LED. If the fault LED is on, check for a fault code on the information panel.
