4.4 Connecting the battery leads
In order to use the full potential of the Quattro, batteries of sufficient capacity and battery leads with the correct cross-section should be
used.

Procedure
To connect the battery leads, follow the procedure below:
To prevent short circuiting of the battery, an isolated box wrench should be
used.
Remove the DC fuse.
•
Loosen the four lower front panel screws at the front of the unit, and remove the lower front panel.
•
Connect the battery leads: + (red) to the right-hand terminal and - (black) to the left-hand terminal (see appendix A).
•
Tighten the connections after mounting the fastening parts.
•
Tighten the nuts well for minimal contact resistance.
•
Replace the DC fuse only after completing the whole installation procedure.

4.5 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.
