impedance. Disconnection can be done by simply unplugging them from the bus
or using external switches.
The Share bus is referenced to the DC minus output terminal. When building a
series connection system (where allowed, depending on model), the DC minus
will shift its potential and thus so will the Share bus.

Slave Units
The 9.3kW or 15 kW Load models can be extended using slave units of the same voltage and
power rating to extend power in a parallel system of up to 32 units in total. Other model
configurations are not possible.
The slave units lack any display and feature a reduced control panel. They cannot be used
stand-alone. They are configured solely to be used under remote control.
The parallel connection system uses master-slave operation and the Share bus. Slave units
can be added incrementally as required. Every unit comes with a master-slave cable to
connect to the next unit. Cables for Share bus and DC Input are not included and must be
manufactured by the user.
When using 19” cabinets, there are DC bus bars available upon request, which are ready to
be mounted directly to the DC Input of the units. Since the number of bus bars and required
screws varies depending on the maximum current you want to achieve, it is necessary to
assemble individual sets. When planning to extend the system by further units, it is advised
to order and install bus bars for the final configuration even when starting with just two
units.
The configuration of the master unit is done either on the unit itself or via software in
remote control. The slave units do not require any setup, as they are preconfigured to
always be slaves on the master-slave bus

Firmware Update
Note: Firmware updates should only be installed when they can eliminate existing bugs in
the firmware in the unit or contain new features.
The firmware of the front panel controller (HMI), the communication unit and the digital
controller can be updated via the rear panel USB device port. For this the APS 6RL Control
software is required which is available as download from our website. Firmware image files
are distributed through customer service.
However, be advised not to install updates casually. Each update includes inherent risk of an
inoperable unit or system. We recommend to install updates only if:
An imminent problem with your unit can directly be solved, especially if suggested
by APS customer service to install an update because of a support case.
A new feature has been added which you definitely need. In this case, the full
responsibility for updating firmware is transferred to the unit owner.
Following considerations also apply to firmware updates:
