5. Configuration
•
Settings may only be changed by a qualified electrical engineer.
• Read the instructions thoroughly before implementing changes.
• During setting of the charger, the DC fuse in the battery connections must
be removed.
5.1 Standard settings: ready for use
On delivery, the Quattro is set to standard factory values. In general, these settings are selected for single-unit operation.
Settings, therefore, do not require changing in the event of stand-alone use.
Warning: Possibly, the standard battery charging voltage is not suitable for your batteries! Refer to the
manufacturer's documentation, or to your battery supplier!

5.2 Explanation of settings
Settings that are not self-explanatory are described briefly below. For further information, please refer to the help files in the
software configuration programs (see Section 5.3).
Inverter frequency
Output frequency if no AC is present at the input.
Adjustability: 60Hz; 50Hz
Input frequency range
Input frequency range accepted by the Quattro. The Quattro synchronises within this range with the voltage present on L1-1 of
AC-in-1 (priority input) or L1-2 of AC-in-2. Once synchronised, the output frequency will be equal to the input frequency.
Adjustability: 45 – 65 Hz; 45 – 55 Hz; 55 – 65 Hz
Input voltage range
Voltage range accepted by the Quattro. The Quattro synchronises within this range with the voltage present on L1-1 of AC-in-1
(priority input) or on L1-2 of AC-in-2. After the back feed relay has closed, output voltage will be equal to input voltage.
Adjustability: Lower limit: 94 - 120V
Upper limit: 120 - 143V
Inverter voltage
Output voltage of the Quattro in battery operation.
Adjustability: 95 – 128V
Stand-alone / parallel operation / 2-3 phase setting
Using several devices, it is possible to:
• increase total inverter power (several devices in parallel)
• create a split-phase system (available only on Quattro units with 120V output voltage)
• create a 3-phase system.
To this end, the devices must be mutually connected with RJ45 UTP cables. Standard device settings, however, are such that
each device operates in stand-alone operation. Reconfiguration of the devices is therefore required.
