INFORMATION FOR THE ELECTRICIAN
7.1 Notes about connection of the pool pumps JETSTREAM COCO 2,5 kW and COCO 3,5 kW
(version without illumination) for threephase 3 N ~ 400 V 50 Hz
This affects your safety!
Therefore, perform all work carefully in accordance with the regulations EN-60335-2-41. You
must definitely observe the safety instructions and the requirements stated by the standards
Warning
authorities.
All work on the pool pump may be performed only by firms having authorisation from the uwe company, or
by trained electrical experts. The EN regulations and the relevant accident prevention regulations must be
observed in all work where voltage is present.
Important notes!
Warning
1
Connection to the indoor wiring
For the connection of the 400 V 3N AC 50 Hz (three-phase) electrical supply to the control panel and motor, a
conductor cross-section of at least 5 x 2.5 mm² CU is necessary (pay attention to the length of the cable). An
all-pole isolating switch with 3 mm contact must be provided in the mains cable.
2
Safety precautions
To prevent shock-hazard voltage, the unit must be made safe by protective grounding as per EN-60335-2-41
and by installing a 30 mA earth leakage circuit breaker (R.C.C.B.). Furthermore, the motor must be connected
as per EN-60335-2-41 to the potential equalisation system.
3
Fusing
For 400 V: 16 A slow-blow fuses, or 16 A automatic circuit-breakers. Pay attention to cable length and voltage
drop.
For 230 V: 16 A slow-blow fuses, or 16 A automatic circuit-breakers. Pay attention to cable length and voltage
drop.
4
Power consumption
The maximum power consumption of the pump units at a nominal voltage of 400 V 3N AC 50 Hz is as
follows:
COCO
BAMBO2, BAMBO, VIVA, LIBRA 3-5, LIDO, LIDO2
EuroJet

Motor protection
The necessary switching and safety elements are accommodated in the control panel, and so there is no need
for any additional motor protection. Please check whether the overcurrent relay is adjusted to suit the rated
current of the motor.
6
Direction of rotation
Please check the direction of rotation. To do this, observe the direction-of-rotation arrow on the pump. To check
the direction of rotation in the dry-running state, switch the pump on for 2 - 3 seconds only, in order to prevent
damage to the rotating mechanical seal. If the direction of rotation is wrong, the flow speed is much lower, and
furthermore the drive motor takes a higher current, and so the overcurrent relay might respond. If the direction
of rotation is wrong, two phase-wires of the mains cable should be interchanged by an electrical expert.
Installing the control panel
Install the control panel in a dry environment, on an internal wall and higher than the water level. Open the control
panel by means of the key supplied. Lead the wires into the control panel through the glands, and connect the
wires in accordance with the wiring diagram. Tighten the glands.
