As an approximate guide, with 400 W pumps, one can expect to pump about 12,000 litres of water with
a full NorthStar NSB 190FT battery. This figure is based upon a system with a new battery and the pumps
operating to approximately a 4 m head with approximately 15 minutes between pumping cycles, allowing for
battery recovery time in between each operation. Further information can be found on page 3 of the Newton
Victron Inverters Data Sheet.
The default set-up of this control panel has the ‘pump duty assist’ disabled when the mains power fails, to
prevent very high current draw from the battery if running two pumps together. This setting protects the
backup battery from sudden discharge and will allow the system to pump more water for much longer with
the limited power supply available in the battery. The default DIP setting is OFF on all four DIPs on both the
Pump 1 and Pump 2 DIP switches.
If pump duty assist is required during a power failure, we recommend that a minimum battery capacity of
380 Ah is used. This is achieved by connecting multiple batteries in parallel (4x 100 Ah or 2 x 191 Ah). To
change the default setting, change DIP 2 on both DIP Switches to ON.
Note:
Battery performance is dictated
by many factors such as the storage temperature and age of the battery, the rising main diameter, overall
length, head and the number of bends, tees and elbows.

Only use Newton Victron Power Inverters coupled with approved and correctly sized NorthStar Batteries
with this control panel. Newton Victron Power Inverters have been designed to work with Newton Pumps
and have special software for battery charging and inverter cooling. All Newton Victron Power Inverters are
tested and calibrated to very high standards before being dispatched from the factory and meet all UK safety
requirements.
Newton Victron Power Inverters include powerful charging circuits and special cooling fan control software.
Newton Power Inverters have a three-stage charging circuit: Bulk - For when the battery is very depleted;
Absorption - For a final top-up charge and Float - A trickle-charge that replaces lost charge. The Inverters are
silent except when in Bulk Mode.
INSTALLATION OF POWER INVERTERS
Power Inverters must be stored in dry conditions before installation. Power Inverters must be installed in a
dry cool area, with good air circulation and NOT directly above the battery or sealed in an airtight box. Do not
install the Power Inverter near the head of a bed or opposite a wall where someone sleeps. All installations
that have grid mains and generated mains power must be correctly labelled, to inform the user that both
power supplies must be isolated before maintenance. Power Inverters can cause electrocution; take great
care to isolate mains and battery before working on systems by unplugging them.
Follow the instructions
included with the Inverter for battery sizing and installation.
Although only 12V, batteries have very high currents of 300 Amps plus, so if you short the terminals with a
spanner, ring or watch for example, they would become white hot in less than 1 second. For this reason you
must remove all metallic rings, watches or any object that may cause a short. If the battery is an open vent
type, you must wear safety glasses and PPE to prevent acid burns. The Power Converter must not have the
mains power connected when fitting the battery cables. Joints must be dry and clean. It is very important
that the connection is good and secure, as a bad joint will heat up and cause the cable insulation to melt (fire
risk), the voltage to vary, and the Power Converter electronics will be damaged. The battery terminals MUST
be covered by a tamper-proof method and not exposed.

WARNING - Outputs from the Control Panel to the Newton Dialer are +5V triggers. DO NOT SHORT
TERMINALS TO +12V TO TEST, AS THIS WILL DAMAGE THE CONTROL PANEL PCB.
Note 1: Connection of the phone line to the panel is only required when the Dialer is fitted within
the panel housing. The panel terminals receive the T & R wires from the phone line and further T & R
wires connect from the terminals to the Dialer, effectively using the panel terminals as a junction box.
If the Dialer is fitted externally to the panel, only the Earth is required from the Dialer to the panel.
