– Screw: Fit cable terminals to the ground (earth) core and the power cores.
– Terminal block: Leave the core ends as they are.
5. Prepare the main leads:
a) Remove the aluminum foil around each power core.
b) Peel the insulation from each power core.
5.3.2 Connect the motor cable to the pump
At delivery from the factory, the motor cable is usually already connected to the pump.
If the cable is not supplied or must be replaced, then contact the sales and service
representative. Unauthorized personnel who opens the connection housing can void the
warranty.
5.3.3 Connect the motor cable to mains and to the monitoring equipment
DANGER: Explosion/Fire Hazard
Special rules apply to installations in explosive or flammable atmospheres. Do not install
the product or any auxiliary equipment in an explosive zone unless it is rated explosion-
proof or intrinsically-safe. If the product is EN/ATEX-, MSHA- or FM-approved, then see
the specific EX information in the Safety chapter before taking any further actions.
NOTICE:
Do not use Variable Frequency Drive (VFD) with this unit.
NOTICE:
Do not use any type of soft start equipment with this unit.
NOTICE:
For insulation tests, the test voltage must be maximum 250 V. The resistance must be
minimum 1 megohm. Only measurements between phase and ground (earth) give valid
results.
NOTICE:
The control leads T3 and T4 must never be extended or broken up in sections. Spliced
control leads can result in interference and signal loss.
• T3, T4: Pump communication
• T1, T2: Sum alarm. The sum alarm relay is normally closed. The rating is 250 VAC, 5 A.
All alarms including leakage, temperature alarms, and failed pump cleaning cycle, are
included in the sum alarm.
On Ex-approved pumps, thermal contacts are connected in series with the sum alarm.
The T1 and T2 leads must always be connected to a protection circuit that disconnects
the power supply to the pump when the contact opens.
NOTICE:
Thermal contacts must never be exposed to voltages higher than 250 V, breaking
current maximum 5 A. It is recommended that they are connected to 24 V over
separate fuses to protect other automatic equipment.
The monitoring equipment can consist of different components.
1. Connect the control leads T1–T4 to the monitoring equipment.
Type of installation Connections
Pump only 1. Connect T1 and T2 to the external controller.
2. Isolate T3 and T4.
