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.
• AC-out-2
A second output is available that disconnects its load in the event of battery operation. On these terminals, equipment is
connected that may only operate if AC voltage is available on AC-in-1, e.g. an electric boiler or an air conditioner. The load on
AC-out-2 is disconnected immediately when the Quattro-II switches to battery operation. After AC power becomes available on
AC-in-1, the load on AC-out-2 will be reconnected with a delay of approximately 2 minutes. This to allow a genset to stabilise.

4.4. Optional Connections
A number of optional connections are possible:
4.4.1. Remote Control
The product can be remotely controlled in two ways.
• With an external switch (connection terminal M, see appendix A). Operates only if the switch on the Quattro-II is set to "on".
• With a
Digital Multi Control
panel (connected to one of the two RJ45 sockets L, see appendix A). Operates only if the switch on
the Quattro-II is set to "on".
See
Appendix A, Connection overview [28]
4.4.2. Programmable relay
The product is equipped with a programmable relay.
The relay can be programmed for all kinds of other applications however, for example as a starter relay for a generator.
See
Appendix A, Connection overview [28]
4.4.3. Programmable analog/digital input/output ports
The product is equipped with 2 analog/digital input/output ports.
These ports can be used for several purposes. One application is communication with the BMS of a lithium-ion battery.
See
Appendix A, Connection overview [28]
4.4.4. Voltage sense
For compensating possible cable losses during charging, two sense wires can be connected with which the voltage directly on the
battery or on the positive and negative distribution points can be measured. Use wire with a cross-section of 0.75mm² (AWG 18).
During battery charging, the Quattro-II will compensate the voltage drop over the DC cables up 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.
See
Appendix A, Connection overview [28]
4.4.5. Temperature sensor
For temperature-compensated charging, the temperature sensor (supplied with the Quattro-II) can be connected. The sensor is
isolated and must be fitted to the negative terminal of the battery.
See
Appendix A, Connection overview [28]
4.4.6. Parallel connection
Up to six identical units can be connected in parallel. When connecting Quattro-II units in parallel, the following requirements must
be met:
• All units must be connected to the same battery.
• A maximum of six units can be connected in parallel.
• Only identical devices may be connected in parallel.
• The DC connection cables to the devices must be of equal length and cross-section.
