Main anchor
The main anchor is installed on the web between pumplets 2 and 3. A cable tie secures the two coil
harnesses and the sensor one to the main anchor.
Coil harness
There are two coil harnesses (“A” and “B”) for the DDP096. Each valve coil needs to be connected to a coil
harness for full pump function and control.
On the pump-to-controller harness end, they can be quickly differentiated by the color and key insert of
the DEUTSCH connector:
•
The coil harness “A” has a gray DEUTSCH connector and connects to the valve coils of pumplets 1 and
2
•
The coil harness “B” has a black DEUTSCH connector and connects to valve coils of pumplets 3 and 4
On the valve connection end, each branch of the coil harness can be paired with the corresponding coil
according to its length and the wire colors:
•
Red for the valves of bank A
•
Black for the valves of bank B
•
White for the valves of bank C
Customer-specific harness may not follow the same color codes; please contact your Danfoss
representative.
Sensor harness
A sensor wiring harness is typically composed of:
•
One branch for the speed and temperature sensor (which has 4 wires in total)
•
One or several branches for the pressure sensor(s) (which each has 2 wires)
All sensors use a male 4-pin circular connector with straight output and M12x1 thread. In the rest of the
document, it is referred as the M12 connector.
A sensor harness exists for each DDP096 service configuration:
•
1-service pump [P]: one pressure sensor is used in port M (single-outlet pump)
•
2-service pump [P1 / (P2 + P4)] or [(P1 + P2) / P4]: two pressure sensors are used in ports M1 and M4
(multi-outlet pump)
•
3-service pump [P1 / P2 / P4]: three pressure sensors are used in ports M1, M2 and M4 (multi-outlet
pump)
More wiring harness options are available on request; please contact your Danfoss representative.
