Xantrex Technology XC2524, XC5012, XC3012, XC1524 AC Wiring, Over-current protection disconnect

Preparing for Installation

Over-current protection disconnect

The DC circuit from the battery to the charger must be equipped with a disconnect and over-current protection device. The device usually consists of a DC-rated circuit breaker, a “fused disconnect”, or a separate fuse and disconnect. These devices must be rated for DC voltage and current. Do not substitute devices rated only for AC voltage; they may not operate properly.

The current rating of the DC fuses must be matched to the size of the DC wiring used, in accordance with the applicable codes.

The DC chassis ground (earth) should not be more than one size smaller than the DC wiring size selected (see Table 1-1). Refer to your local electrical codes for verification.

AC Wiring

The AC wiring must meet the following requirements before you install the XC Series:

The AC input wiring for the XC Series should be three-conductor cable, providing a line, neutral, and ground conductor (or L1, N, GND) in an outer jacket.

For example, in North America for 120 VAC use a 14 AWG wire with a 15 A breaker; or typically in Europe for 230 VAC use either a 2.5mm2 wire with a 16 A, double pole breaker or fuse or use 1.5 mm2 wire with a 10 A, double pole breaker or fuse. Note that every jurisdiction will have different requirements, so see the regulations for your local jurisdiction to determine which wire size and type is correct. A second example:

•for marine applications the United States ABYC requires stranded wire, which is more robust than solid wire when exposed to vibration

•for RV applications, the United States NEC allows solid wire in multi- conductor cable, but stranded wire will withstand vibration better.

The circuit supplying the XC Series must be protected by the correct size and type of breaker to meet the code for your local jurisdiction and application. If a fuse is used, a disconnect switch is needed ahead of the fuse.
