Installing the XC Series
Pre-Installing DC Wiring
The procedure for installing the DC wiring applies to a single battery or multiple batteries or battery banks.
WARNING: Shock or arc burn hazard
To help prevent accidental shorts or sparks, leave the DC disconnects or breakers in the Off position or fuses removed from their fuse holders until installation is complete.
Important: Xantrex recommends that you install the rubber boots over the XC Series DC terminals to provide drip protection and increased protection from short circuits. You need to install the boots before doing any other DC wiring. See “To install rubber boots:” on page
To install DC wiring:
1.Identify the battery or bank that most frequently becomes deeply discharged. This bank will often be a deep cycle battery referred to as the House Bank on a boat, as opposed to an engine Start Battery. This high priority bank should be connected to bank 1 on the XC Series, which is the default bank.
2.Plan the route that the DC wires will follow, keeping it as short as possible. Measure and cut the required wire length. Allow some extra length for connections and to provide slack in the wires.
Note: The connection to the battery negative circuit may not be at a battery, but may be at an engine negative bus or a DC negative bus. If in doubt, consult the boat schematics.
3.Identify the positive wires, by using
Important: You may find it helpful to label each cable, associating it with the battery bank it is connected to. For example, bank 1
4.Install a DC circuit breaker or fuse/disconnect in each positive cable close to each battery. For your applications and jurisdiction, consult your local electrical codes regarding the distance between the battery and the disconnect device. Be sure the breaker is open or fuse is not inserted at this time.
