CONNECTION AND START-UP
4.1
Connecting the mechanical system
WARNING
Hot motor housing
Fire hazard
→ Ensure that no combustible or flammable materials
are located close to the pump.
CAUTION
Cutting and crushing hazard when removing the
device from the packaging.
→ Carefully remove the device from its packaging only
touching the housing. Make sure to avoid any shock.
→ Wear safety shoes and cut-resistant safety gloves.
Check the device for transport damage. Damaged decvices
must no longer be installed.
Install the undamaged device according to your application.
4.2
Connecting the electrical system
DANGER
Electric voltage on the device
Electric shock
→ Always install a protective earth first.
→ Check the protective earth.
→ Use the device only with the cable guard and
terminalbox provided for this prupose.
DANGER
Incorrect insulation
Risk of fatal injury from electric shock
→ Use only cables that meet the specified installation
requirements for voltage, current, insulation material,
load etc.
→ Route cables such that they cannot be touched by
any rotating parts.
NOTE
Water penetration into leads or wires
Water enters at the cable end on the customers’ side
or the terminal box can damage the device.
→ Make sure that the cable end and terminal box is
in a dry environment.
Connect the device only to circuits that can be
switched off using an all-pole disconnecting switch.
4.2.1
Prerequisites
Check whether the data on the type plate agree with the
connection data and the data of the operating capacitor.
Before connecting the device, ensure that the supply
voltage matches the operating voltage of the device.
Only use cables designed for current according to the type
plate. For determining the cross-section, follow the basic
principles in accordance with EN 61800-5-1. The protective
earth must have a cross-section equal to or greater than the
outer conductor cross- section.
We recommend the use of 105°C cables. Ensure that the
minimum cable cross-section is at least AWG26/0.13 mm².
Earth wire contact resistance in accordance with EN 60335
Compliance with the impedance specifications in accordance
with EN 60335 for the protective earth circuit must be verified in
the end application.
Depending on the installation situation, it may be necessary to
install an additional protective earthing conductor via the
additional protective earth connection point available on the
device.
4.2.2
Voltage control
With open loop speed control using transformers or
electronic voltage regulators (e.g. phase angle
control), excessive current may occur.
In addition, noises can occur with phase angle control
depending on the mounting situation
4.2.3
Frequency converter
Please use a frequency converter only after consultation with
ebm-papst A&NZ.
For operation with frequency converters, fit sinusoidal
filters that work on all poles (phase-phase and phase-
earth) between the frequency converter and the
motor.
During operation with frequency converters, an all-
pole sine filter protects the motor against high-voltage
transients that can destroy the winding insulation
system, and against harmful bearing currents.
Heating of the motor due to use of a frequency converter must
be checked in the application by the customer.
4.3
Connection of the terminal
Terminal strip located in junction box
First connect the “PE” (protective earth) connection.
Connect the lines according to your application. When
doing so, observe chapter 4.4 Connection Screen.
