Connection Of The Ac Cabling; Optional Connections - Victron energy EasySolar-II GX Product Manual

8.5. Connection of the AC cabling

This product is a safety class I device, intended for a TN system (supplied with a ground terminal for safety
purposes). Its AC input and/or output terminals must be provided with uninterruptible grounding for
safety purposes. An additional grounding point bonded to the chassis is located inside the terminal
cover of the product. See Appendix A.
In a fixed installation, an uninterruptible grounding can be secured by means of the grounding wire of the AC
input. Otherwise the casing must be grounded.
This product is provided with a ground relay (relay H, see Appendix B) that automatically connects the
Neutral output to the chassis if no external AC supply is available. If an external AC supply is provided,
the ground relay H will open before the input safety relay closes. This ensures the correct operation of an
earth leakage circuit breaker that is connected to the output.
In a mobile installation (for example, with a shore current plug), interrupting the shore connection will
simultaneously disconnect the grounding connection. In that case, the casing must be connected to the
chassis (of the vehicle) or to the hull or grounding plate (of the boat). In case of a boat, direct connection to
the shore ground is not recommended because of potential galvanic corrosion. The solution to this is using an
isolation transformer. Torque: 2 Nm
The terminal blocks can be found on the printed circuit board, see Appendix A.
Do not invert neutral and phase when connecting the AC.
• AC-in The AC input cable can be connected to the terminal block 'AC–in'. From left to right: "N" (neutral), "PE" (earth) and "L"
(phase) The AC input must be protected by a fuse or magnetic circuit breaker rated at 32A or less, and cable cross-
section must be sized accordingly. If the input AC supply is rated at a lower value, the fuse or magnetic circuit breaker
should be down sized accordingly.
• AC-out-1 The AC output cable can be connected directly to the terminal block 'AC-out'. From left to right: "N" (neutral), "PE"
(earth) and "L" (phase) With its PowerAssist feature the Multi can add up to its rated power (e.g 3000 / 230 = 13A) to the output
during periods of peak power requirement. Together with a maximum input current of 32A this means that the output can supply
up to 32 + 13 = 45 A. An earth leakage circuit breaker and a fuse or circuit breaker rated to support the expected load must be
included in series with the output, and cable cross-section must be sized accordingly.
• AC-out-2 A second output is available that disconnects its load in the event of battery operation. On these terminals,
equipment is connected that may only operate if AC voltage is available on AC-in-1, e.g. an electric boiler or an air conditioner.
The load on AC-out-2 is disconnected immediately when the inverter/charger switches to battery operation. After AC power
becomes available on AC-in-1, the load on AC-out-2 will be reconnected with a delay of approximately 2 minutes. This to allow
a genset to stabilise
