When installing the LPS the following connections can be used.
- 230VAC Input for charging from external mains plug (Blue Neutrik. Assembly described in section 6.3)
- 230VAC output to power 230vac equipment (Grey Neutrik. Assembly described in section 6.3)
- 12VDC Input for charging from the car generator (12VDC input, Grey Anderson SB50. Assembly
described in section 6.6)
- 12VDC output to power 12VDC equipment (12VDC output, Red Anderson SB50. Assembly described in
section 6.6)
6.1. Installation / Use of 230VAC Input
When connecting the LPS1512-100Ah to a 230VAC source, the unit will start up and begin to charge the
internal battery. Please note that when a 230VAC source is connected the unit will loop the 230VAC directly
through to the output sockets, enabling 230VAC out.
Note: Always use a RCD protected source to supply the LPS 1512-100Ah from 230VAC.
When installing the LPS into a vehicle it is important that the 230VAC in is supplied from an unbroken cable
from the external power source to the 230VAC input on the LPS as shown in figure 4.
If the 230VAC charge wire is connected to anything else, an RCD must be present immediately after the
input socket as shown in figure 5.
Figure 4
Figure 5

Lithium Power Supply User Manual
6.2. Installation / Use of 230VAC Output
Fuses
Both 230VAC outputs on the LPS (Schuko on the front, Neutrik in the back) are protected with 8A relays
and a RCD, which allows you to make fixed 230VAC installations in the vehicle. If an installation is wired
around the LPS, separate relays must be used.
Connections
For fixed 230VAC installations from the LPS the Neutrik 230VAC Out on the backside must be used. This is
to ensure that vibrations will not loosen the connection.
General function
When 230VAC In is connected the 230VAC power will be looped directly through the unit.
If both 230VAC In and 230VAC Out are running and 230VAC In is subsequently disconnected, the LPS will
change from charge to discharge mode and continue to deliver 230VAC Out.

Lithium Power Supply User Manual
6.4. Use of 12VDC Input
In order to charge from the 12VDC starter battery of the vehicle the diagram in figure 7 must be followed.
Please note that a fuse must be placed as close to the starting battery as possible.
Figure 7
Note: Fuses can be purchased at your Clayton Power sales representative.
For the LPS to charge from the surplus energy from the vehicle, the D+ signal from the generator must be
connected to pin 9 of the communications connector.
This signal insures the LPS is activated and only charges from the vehicle when the engine is running.
NOTE: When the signal in pin 9 of the communications connecter is active (high) the power botton on the
fron panel is not functional.

9. Additional information
Battery Management System
The LPS has a built-in Battery Management System ensuring full control and safety. The BMS monitors
lithium cell activity and uses the information for safety, maintenance, SOC, and interface control.
Charger Control
It is necessary to control the charging of lithium batteries in order to avoid uncontrolled disconnections and
to protect the lithium cells from unstable conditions. The integrated Battery Management System always
ensures the lithium cells are operated within their safe operating parameters.
Cell voltage measurement
The LPS measures cell voltage with high accuracy. The accuracy is necessary to calculate the SOC as only
a few 1/1000 of a volt makes a difference.
Cell temperature measurement
The LPS measures the temperature of all individual cells to ensure that none of the cells overheat or cause
thermal runaway. The temperature information is also used for SOC calculations.
Shunt and current measurement
The current passes through an integrated shunt resistor so the LPS can measure the current to and from
the cells and use it for protection and SOC calculation.
Integrated safety breaker
The most important part of the LPS circuit protection is the integrated safety breaker. It allows the LPS to
cut off all charge and discharge currents in potentially hazardous situations.
Overload protection
The advantage of the internal safety breaker is its capability to disconnect high currents without damaging
the main switch. The LPS can use the safety breaker for overload protection without damaging the cells.
Short-circuit protection
The LPS is protected against short circuits by fuses on the inputs and outputs.
The 230VAC output furthermore has a built-in RCD to protect the user.
Cell balancing
The advanced SOC calculation ensures that all cells are kept in a balanced condition at all times. The BMS
has a high cell-balance current that reduces the need for active cell balancing and restores the cells to a
balanced condition faster. The BMS is cell balancing each single cell in charge, discharge and idle mode.

Interface
Each LPS has a service interface that allows a qualified technician to analyse any failures and the general
condition of the LPS. The service port also allows for firmware updates.
Power conservation
When the LPS is not in use it will enter a low power state. In this state the LPS keeps power consumption
very low to avoid unnecessary discharge of the battery. The LPS can be reactivated through the power
switch or by applying a charge source to either the 230VAC input or the 12VDC input.
