Installing the HI400

AC output neutral bonding

The neutral conductor of the inverter’s AC output circuit is automatically connected (“bonded”) to the safety ground whenever the inverter is running and AC utility shorepower is not present. When AC shorepower is present, this connection is automatically lifted, as that same bonding connection will be present in the AC shorepower source. This system automatically conforms to electrical code requirements that neutral conductors are to be bonded to ground at all times, but only in one place at a time.

CAUTION: Damage to unit

Do not connect AC output to any AC load circuit in which the neutral conductor is connected to ground (earth) or to the negative of the DC (battery) source. Doing so will damage the unit.

DC disconnects and over-current devices

The DC circuit from the battery to the inverter must be equipped with over-current protection (such as a circuit breaker or fuse) and a disconnect device. This usually consists of a DC-rated circuit breaker, a “fused-disconnect,” or a separate fuse and DC disconnect. Do not confuse AC circuit breakers with DC circuit breakers — they are not interchangeable. The current rating of the fuse or breaker must be matched to the size of the DC cables used in accordance with the applicable installation codes. The breaker or disconnect and fuse should be located as close as possible to the battery, in the positive cable. Applicable codes may limit how far the protection can be from the battery.

For No. 8 AWG DC cable, the fuse or circuit breaker is required to be rated 40 Adc max. Use a slow-blow fuse to get the maximum surge performance from the inverter.
