ESIGN
The control unit is incorporate into the front door of the switchboard. The front meets the protection class
IP 44 when installed. The two rows of LEDs are marked with interchangeable labels. The relay unit is
mounted on the mounting plate and linked to the control unit in the door with the supplied cable.
The control unit has an optic fibre or USB interface (selected by a toggle switch) for the connection of a PC.
The following settings (password protected) and analogue readouts are possible.

ONNECTION
−
Trained experts may only make the connections of the KEA.
−
The PE(N) must be connected for security reasons to terminal 5 on the X403.
−
The charging device must be switched off before the battery is disconnected.
−
When the supply voltage of the control unit has been switched off, you must wait at least 20
seconds before applying it again.
−
The negative pole of the battery must be grounded at the input terminal of the switchboard. The
minimum conductor cross-section is 10 mm
2
.
−
The supply voltage can be set to 12 or 24 V DC with a switch on the RZ 071-D.
−
The screens of the analogue input wiring must be connected to the earth screws on the KEA cover,
and must have no connection to any other metal parts.
−
All coils must be fitted with reverse diodes to prevent high voltage peaks. All other coils or
inductive loads must also be fitted with suppressor elements. The same applies for all relays and
inductors that are used in the switchboard or controlled externally.
The following signals (if needed) are directly applied to the control unit:
−
Voltage of mains and generator,
−
Current of generator,
−
Four analogue sensors,
−
Pick-up,
−
Two analogue output signals,
−
Optical fibre or USB for parameterisation,
−
Two CAN bus systems.
Although the control system is protected against reverse polarity, the correct polarity when connecting the
battery voltage must be strictly observed, as reverse diodes or other electronic parts of the switchboard may
possibly be damaged.
The fuse on the RZ 071-D will be blown, if the control system is connected
with the wrong polarity!
Due to the fact that most of the control relays may be configured for various functions, only the status print
out of the supplied control unit is to be considered as a binding document. It must be observed, that in case of
a possible replacement of a unit, any modifications made after commissioning cannot be taken into account
by the manufacturer.
Changes without further notice reserved.
