The pumps must be connected to an electrical installation in compliance
with the decree 88-1056 dated 14 November 1988, as well as any local
electrical codes that apply.
• Our products are designed to meet current EEC regulations. Any
modication on the part of the user is liable to cause non-compliance with
regulations or even affect the EMC (Electromagnetic compatibility) performance
and safety of the product. Alcatel cannot be held responsible for consequences
resulting from such an intervention.
• Before any maintenance is performed on a product by a maintenance operator
who has not been trained on safety regulations (EMC, electrical safety, chemical
pollution, etc.), isolate the product from its various energy sources
(electricity, compressed air, etc.).
As a general rule, it is recommended to protect the motor for 120% of its
nominal current (see page 72).
• Check that the electrical wiring and the voltage selector position of the motor
correspond to the line voltage, before starting up the pump.
• Ensure that the electrical installation conforms with your local safety
requirements. It must include the appropriate fuse and reliable earthground.
Electrical motor is in accordance with major international standards (UL, CSA, CE)
and offers two voltage ranges:
- Law voltage: 170 V to 254 V 50Hz - 170 V to 300 V 60Hz,
- High voltage: 342 V to 460 V 50Hz - 342 V to 520 V 60Hz.
All three phase motors (protection level IP 43. TEFC type) must be protected by a
customer supplied starter consisting of a suitably rated contactor and thermal overload.
Furthermore, they are equipped with a dry contact (NC) thermal protection which
is available in the therminal box.
Wire the motor according to the line voltage. The connections to be made are
shown on a diagram inside the terminal box or on its lid.
Check the direction of rotation of the motor (direction of arrow located on the
motor cover). For this:
- Remove the protective caps on the inlet and exhaust orifices.
- Vent the pump to atmospheric pressure.
- Switch on the pump for 2 to 3 seconds, with your hand on the inlet orifice
if suction is felt, the wiring is correct.
Otherwise, invert 2 consecutive phases.
The earth terminal must be connected correctly.
Electrical motor is in accordance with major international standards (UL, CSA, CE)
and offers two voltage ranges:
- Low voltage: 90 V to 132 V 50/60Hz,
- High voltage: 180 V to 254 V 50/60Hz.
Note: single-phase motors (protection level IP 43 - TEFC type) have a thermal circuit
interruptor with an automatic starting device: when the internal motor temperature
reaches a value over the preset limit value, the motor stops.
However, when the motor is cooled, it will start up again automatically.
Before connecting to the mains, check the position of the voltage selector: High
Voltage (HV) or Low Voltage (LV) (see table page 73).
The plug is equipped with a ground pin which must be connected.
The motor rotation direction is set at the factory.
