4.4 Connection options

4.4.1 Starter battery (connection terminal E, see appendix A)

The Quattro has a connection for charging a starter battery. Output current is limited to 4A.

(not available on 48V models)

4.4.2 Voltage sense (connection terminal E, see appendix A)

For compensating possible cable losses during charging, two sense wires can be connected with which the voltage direct on

the battery or on the positive and negative distribution points can be measured. Use at least wire with a cross-section of

0,75mm2.

During battery charging, the Quattro will compensate the voltage drop over the DC cables to a maximum of 1 Volt (i.e. 1V over

the positive connection and 1V over the negative connection). If the voltage drop threatens to become larger than 1V, the

charging current is limited in such a way that the voltage drop remains limited to 1V.

4.4.3 Temperature sensor (connection terminal E, see appendix A)

For temperature-compensated charging, the temperature sensor (supplied with the Quattro) can be connected. The sensor is

isolated and must be fitted to the negative terminal of the battery.

4.4.4 Remote control

The Quattro can be remotely controlled in two ways:

- With an external switch (connection terminal H, see appendix A). Operates only if the switch on the Quattro is set to “on”.

- With a remote control panel (connected to one of the two RJ48 sockets B, see appendix A). Operates only if the switch on the

Quattro is set to “on”.

Using the remote control panel, only the current limit for AC-in-2 can be set (in regard to PowerControl and PowerAssist).

The current limit for AC-in-1 can be set with DIP switches or by means of software.

Only one remote control can be connected, i.e. either a switch or a remote control panel.

4.4.5. Programmable relays (connection terminal I and E (K1 and K2), see appendix A

The Quattro is equipped with 3 programmable relays. The relay that controls terminal I is set as an alarm relay (default setting).

The relays can be programmed for all kinds of other applications, for example to start a generator (VEConfigure software

needed).

4.4.6 Auxiliary AC output (AC-out-2)

Besides the usual uninterruptable output (AC-out-1), a second output (AC-out-2) is available that disconnects its load in the

event of battery operation. Example: an electric boiler or air conditioner that is allowed to operate only if the genset is running or

shore power is available.

In case of battery operation, AC-out-2 is switched off immediately. After the AC supply has become available, AC-out-2 is

reconnected with a delay of 2 minutes, this allow a genset to stabilise prior to connecting a heavy load.

4.4.7 Connecting Quattro’s in parallel (see appendix C)

The Quattro can be connected in parallel with several identical devices. To this end, a connection is established between the

devices by means of standard RJ45 UTP cables. The system (one or more Quattro’s plus optional control panel) will require

subsequent configuration (see Section 5).

In the event of connecting Quattro units in parallel, the following requirements must be met:

- A maximum of 6 units connected in parallel.

- Only identical devices with the same power ratings may be connected in parallel.

- Battery capacity should be sufficient.

- The DC connection cables to the devices must be of equal length and cross-section.

- If a positive and a negative DC distribution point is used, the cross-section of the connection between the batteries and the

DC distribution point must at least equal the sum of the required cross-sections of the connections between the distribution

point and the Quattro units.

- Place the Quattro units close to each other, but allow at least 10 cm for ventilation purposes under, above and beside the

units.

- UTP cables must be connected directly from one unit to the other (and to the remote panel). Connection/splitter boxes are not

permitted.

- A battery-temperature sensor need only be connected to one unit in the system. If the temperature of several batteries is to be

measured, you can also connect the sensors of other Quattro units in the system (with a maximum of one sensor per Quattro).

Temperature compensation during battery charging responds to the sensor indicating the highest temperature.

- Voltage sensing must be connected to the master (see Section 5.5.1.4).

- Only one remote control means (panel or switch) can be connected to the system.

4.4.8 Three-phase configuration (see appendix C)

Quattro’s can also be used in 3-phase wye (Y) configuration. To this end, a connection between the devices is made by means

of standard RJ45 UTP cables (the same as for parallel operation). The system (Quattro’s plus an optional control panel) will

require subsequent configuration (see Section 5).

Pre-requisites: see Section 4.4.7.

Note: the Quattro is not suitable for 3-phase delta (Δ) configuration.
