4.3 Connecting AC cables
The Quattro is a safety class I product (supplied with an ground terminal for safety
purposes). Its AC input and/or output terminals and/or grounding point on
the outside of the product must be provided with an uninterruptable
grounding point for safety purposes. See the following instructions in this
regard.
The Quattro is provided with a ground relay (see appendix) that automatically
connects the N output to the casing if no external AC supply is available. If
an external AC supply is provided, the ground relay will open before the input
safety relay closes (relay H in appendix B). This ensures the correct operation of
an earth leakage circuit breaker that is connected to the output.
- In a fixed installation, an uninterruptable grounding can be secured by means of
the grounding wire of the AC input. Otherwise the casing must be grounded.
- 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 general, the connection described above to shore connection grounding is not
recommended for boats because of galvanic corrosion. The solution to this is
using an isolating transformer.
AC-in-1 (see appendix A)
If AC voltage is present on these terminals, the Quattro will use this connection. Generally a generator will be connected to AC-
in-1.
AC-in-1 is internally protected by a 30A thermal circuit breaker.
AC-in-2 (see appendix A)
If AC voltage is present on these terminals, the Quattro will use this connection, unless voltage is also present on
AC-in-1. The Quattro will then automatically select AC-in-1. Generally the mains supply or shore voltage will be connected
to AC-in-2. AC-in-2 is internally protected by a 30A thermal circuit breaker.
AC-out-1 (see appendix A)
The load is connected to these terminals. If AC voltage is available on AC-in-1 or AC-in-2, AC-out-1 will be connected through
with AC-in-1 (priority input) or AC-in-2. If no AC voltage is available, AC-out-1 will be supplied by the inverter. An earth leakage
circuit breaker and an automatic fuse for a maximum of 63A must be included in series with AC-out-1. (Maximum of 30A input
current plus a maximum of 30A for additional inverter current). The cable cross-section used must therefore also be
suitable for currents up to 63A, unless the input current is limited to a lower value.
AC-out-2 (see appendix A)
On these terminals, equipment is connected that may only operate if AC voltage is available on AC-in-1 or AC-in-2, e.g. an
electric boiler.
An earth leakage circuit breaker must be included in series with AC-out-2, and possibly an automatic fuse for a maximum of
16A.
Procedure
Use three-core cable. The connection terminals are clearly encoded:
PE: earth
N: neutral conductor
L: phase/live conductor
