Section 4: Inverter/Charger Installation
8.If you are using the remote temperature sensor, plug it into the temperature sensor jack (BATT TEMP) on the side of the Prosine inverter/charger chassis. Route the sensor wire safely to the battery location and mount the sensor's ring tongue connector directly on the NEGATIVE battery post. Do not mount the sensor between the DC negative power cable and the negative battery terminal.
9.For residential installations, a DC wiring enclosure is required to cover DC connections and cables. Contact Xantrex or your distributor for this part. For other installation, install the red and black DC terminal covers over the positive and negative terminals, respectively.
DC Grounding
The Prosine inverter/charger has a lug on the rear panel labeled Chassis Ground. This lug is used to connect the chassis of the inverter/charger to your DC ground as is required by regulations for some installations. Depending on where the inverter/charger is being installed, follow the instructions below that correspond to your installation location.
Recreational Vehicle InstallationsUse #8 AWG or larger copper wire (green if insulated) and secure it to the Chassis Ground Lug as well as the grounding point in your vehicle (usually the vehicle chassis).
Residential InstallationsThe chassis of the Prosine inverter/charger must be connected to the system’s DC grounding point. Typically wire is #2 AWG
The Chassis Ground Lug should be connected to the boat’s Engine Negative bus or DC Grounding bus. The ABYC recommends the following, based on 75 C wire:
•PS2.5/12: # 1/0 AWG
•PS3.0/12: # 2/0 AWG
•PS2.5/24: # 3 AWG
•PS3.0/24: # 1 AWG
Connecting the Battery Temperature Sensor
Mounting Options
You can mount the battery temperature sensor (BTS) in one of two ways:
•Mounting the sensor to the negative battery post allows the internal battery temperature to be sensed and provides the most accurate results.
