This guide for use by qualified personnel only

Size of AC Input Wiring Wire size must be coordinated with the overcurrent

protection provided ahead of the wire involved, in accordance with the electrical

codes or regulations applicable to your installation.

Therefore, the wiring used between the main AC source panel’s circuit breaker

and the inverter/charger AC INPUT must be sized to match the input breaker

rating.

Size of AC Output Wiring Wire size must be coordinated with the current the

wiring will carry. For example, this current may be determined by the 15-amp

maximum inverter current, or by the bypass current, which is determined by the

overcurrent protection provided ahead of the Conext SW 4024 120/240.

Size of Wiring Downstream of the AC Output Breaker The wiring used

between the AC output breaker and your loads must be sized to match the

output breaker.

DC Component -

Batteries

The Conext SW system requires a 24-volt, lead-acid deep-cycle battery or group

of batteries to provide the DC current that the inverter/charger converts to AC

power. The battery may be a flooded, gel, or AGM type.

See “Battery Information” on page 1–37 for information on:

• Estimating the battery size that will meet your requirements.

• Designing battery banks.

• Restrictions on the size of appliances.

For information on cabling and hooking up batteries, see “Battery Cabling and

Hook-up Configurations” on page 1–41.

For detailed information about specific brands of batteries, consult individual

battery manufacturers or a local battery distributor.

DC Cabling Definition DC cabling and connectors between the batteries, the DC

disconnect and overcurrent protection device, and the inverter/charger.

Type All installations require multi-strand insulated cables. The DC cables must

be copper and must sized based on 75 °C ampacity and must have an insulation

rating of at least 75 °C.

Size and Length See Table 1-2 for required DC cable length, cable size and

required fuse size for the Conext SW. Wire size is usually marked on the cables.
