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, maximum torque: 7 Nm)

If AC voltage is present on these terminals, the Quattro will use this connection. Generally a generator will be connected to AC-

in-1.

The AC-in-1 input must be protected by a fuse or magnetic circuit breaker rated at 100A 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-in-2 (see appendix A, maximum torque: 7 Nm)

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.

The AC-in-2 input must be protected by a fuse or magnetic circuit breaker rated at 100A 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.

Note: The Quattro may not start when AC is present only on AC-in-2, and DC battery voltage is 10% or more below

nominal (less than 11 Volt in case of a 12 Volt battery).

Solution: connect AC power to AC-in-1, or recharge the battery.

AC-out-1 (see appendix A, maximum torque: 7 Nm)

The AC output cable can be connected directly to the terminal block "AC-out".

With its PowerAssist feature the Quattro can add up to 5, 8, 10 or 15kVA (forexample 10.000 / 230 = 43A) to the output during

periods of peak power requirement.

Together with a maximum input current of 100A this means that the output can supply up to 100 + 21 = 121A (5kVA models),

100 + 35 = 135A (8kVA models), 100 + 43 = 143A (10kVA model) and 100 + 65 = 165A (15kVA model).

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. The maximum rating of the fuse or circuit

breaker is 125A (5kVA models), 135A (8kVA), 143A (10kVA) resp. 165A (15kVA).

AC-out-2 (see appendix A, maximum torque: 7 Nm)

A second output is available that disconnects its load in the event of battery operation. On these terminals, equipment is

connected that should operate only if AC voltage is available on AC-in-1 or AC-in-2, e.g. an electric boiler or an air

conditioner. The load on AC-out-2 is disconnected immediately when the Quattro switches to battery operation. After AC power

becomes available on AC-in-1 or AC-in-2, the load on AC-out-2 will be reconnected with a delay of approximately 2 minutes.

This to allow a genset to stabilise.

AC-out-2 can support loads of up to 50A. An earth leakage circuit breaker and fuse rated at max. 50A must be connected in

series with AC-out-2.

Procedure

Use three-core cable. The connection terminals are clearly encoded:

PE: earth

N: neutral conductor

L: phase/live conductor
