DKG-509 User Manual V-29
(23.08.2013)

The unit is designed for panel mounting. The user should not be able to access parts of the
unit other than the front panel.
Mount the unit on a flat, vertical surface. Before mounting, remove the mounting brackets and
connectors from the unit, then pass the unit through the mounting opening. The unit will be maintained in
its position by the mounting brackets spring.
The output of the current transformers shall be 5 Amperes. The input current rating of the current
transformers may be selected as needed (between 10/5 and 9000/5 amps). Current transformer outputs
shall be connected by separate cable pairs from each transformer, to related inputs. Never use common
terminals or grounding. The power rating of the transformer should be at least 5 VA. It is recommended to
use 1% precision transformers.
If analogue senders (e.g. temperature, oil pressure or fuel level) are connected to the unit, it is not
possible to use auxiliary displays, otherwise the unit may be damaged. If temperature or oil pressure or
fuel level displays are already present on the generator control panel, do not connect the senders to the
unit. The unit is factory programmed for VDO type senders. However different types of senders are
selectable via programming menu. Please check the programming section.
The programmable digital inputs are compatible with both
‘normally open’
and
‘normally
closed’
contacts, switching either to
BAT-
or
BAT+
.
The charge alternator connection terminal provides also the excitation current, thus it is not
necessary to use an external charge lamp.
WARNING: ELECTRICITY CAN KILL
ALWAYS disconnect the power BEFORE connecting
the unit.The fuse rating should be 6 Amps.
1) ALWAYS remove the plug connectors when inserting wires with a
screwdriver.
2) An appropriate and readily accessible set of disconnection devices
(e.g. automatic fuses) MUST be provided as part of the installation.
3)
The building mains supply MUST incorporate appropriate short-circuit
backup protection (e.g. a fuse or circuit breaker) of High Breaking
Capacity (HBC, at least 1500A).
WARNING: THE UNIT IS NOT FUSED.
Use external fuses for Mains phases: L1,L2,L3,
Generator phase: L1,L2,L3, Battery positive: BAT(+).
Install the fuses as nearly as possible to the unit in a
place easily accessible for the user.
The fuse rating should be 6 Amps.
Engine body must be grounded for correct operation of
the unit, otherwise incorrect voltage and frequency
measurements may occur.
