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

Procedure
To connect the battery cables, follow the procedure below:
To prevent short circuiting of the battery, an isolated box wrench should be
used.
• Loosen the four lower front panel screws at the front of the unit, and remove the lower front panel.
• Connect the battery cables: + (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.
4.5 Connecting AC cables
The Quattro is a safety class I product (supplied with a 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 uninterruptible
grounding point for safety purposes. See the following instructions in this
regard.
The Quattro is provided with a ground relay (see fig 1)) 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 H will open before the input
safety relay closes (relay R1 or R2). 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 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.
AC-in-1 (see fig 1)
If 120VAC voltage is present between N1 and L1-1, the Quattro will use this connection. Generally a generator will be
connected to AC-in-1.
AC-in-1 must be protected by a fuse or magnetic circuit breaker rated at 60A or less, and cable cross-section must be
sized accordingly. If the input AC is rated at a lower value, the fuse or magnetic circuit breaker should be down sized
accordingly.
AC-in-2 (see fig 1)
If AC voltage is present between N2 and L1-2, 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 utility grid will be connected to AC-in-2.
AC-in-2 must be protected by a fuse or magnetic circuit breaker rated at 60A or less, and cable cross-section must be
sized accordingly. If the input AC is rated at a lower value, the fuse or magnetic circuit breaker should be down sized
accordingly.
AC-out (see fig 1)
The load is connected to these terminals. If AC voltage is available on AC-in-1 or AC-in-2, AC-out will be connected through
with AC-in-1 (priority input) or AC-in-2.
The Quattro switches to inverter operation when no AC source is available. The inverter output is 120V single phase. In Invert
mode, the Quattro connects both output legs (L1 and L2) together to supply 120VAC to loads on either line. The line to line
voltage will be zero. Any 240VAC or 208VAC loads will therefore be supplied only when the Quattro is supplied by a split phase
