7.3.1
Connecting the inverter to the power grid
The grid connection leads are connected on the right side of the connection area (see fi gure 7).
DANGER
Risk of fatal injury due to electric shock
Severe injuries or death will result if the live connections are touched.
›
Disconnect the inverter from all power sources before you insert the grid power lead into the unit.
CAUTION
Risk of fi re
Insuffi
cient over-current protection can increase the risk of fi re.
›
Connect only to a circuit provided with a branch circuit over-current protection in accordance with the
national electrical code ANSI/NFPA 70.
›
XP10U-H4 / PSD*: 20 A
›
XP10U-H6 / PSD*: 15 A
* OCPD rating unchanged with PSD
AC circuit voltage drop of 2% or less is recommended for runs of greater than 60 feet from the point of common coupling (PCC).
AC conductor ampacity calculations are based on the NFPA 70 and additional requirements.
NOTICE
This unit is provided with adjustable trip limits and can be aggregated above 30kW on a single point of
common connection.
NOTICE
The installation shall indicate wiring methods in accordance with NFPA 70 and additional local require-
ments.
NOTICE
Use copper conductors only.
NOTICE
When impedance of the AC circuit to the utility connection is high, the voltage at the grid terminals of the
inverter will increase during feed-in to the utility. The inverter monitors this voltage, and if the value
exceeds the country-specifi c threshold value, the inverter will disconnect with an error message.
