Operating instructions
W6E630-GN01-01
Translation of the original operating instructions
Connect the device only to circuits that can be switched off
using an all-pole disconnecting switch.
4.2.1 Prerequisites
;
Check that the data on the type plate match the connection data.
;
If the operating capacitor is not installed by ebm-papst, check whether
the data of the operating capacitor match the data on the type plate.
;
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.
Protective earth contact resistance as per EN 61800-5-1
Compliance with the resistance specifications as per EN 61800-5-1 for
the protective earth connection circuit must be verified in the application.
Depending on the installation situation, it may be necessary to connect
an additional protective earth conductor by way of the extra protective
earth terminal provided on the device. The protective earth terminal is
located on the housing and provided with a protective earth symbol and
a hole.
4.2.2 Residual current operated device
If the use of a residual current device (RCD) is required in your
installation, only pulse current-sensitive and/or universal
residual current devices (type A or B) are permissible.
Residual current devices (RCD) cannot provide personal safety
while operating the device, as is also the case with frequency
converters.
4.2.3 Voltage control
NOTE
Excessive current may occur with speed control using
transformers or electronic voltage regulators (e.g. phase angle
control). In addition, depending on how the unit is installed,
noise and vibration can occur with phase angle control.
Vibrations can lead to bearing damage, which can lead to
premature failure.
Heating-up of the motor when using voltage control must be checked by
the customer following installation in the end device.
4.2.4 Frequency inverter
Please use a frequency converter only after consultation with ebm-papst.
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-up of the motor when using a frequency converter must be
checked by the customer following installation in the end device.
4.3 Connection in terminal box
4.3.1 Preparing connection lines for the connection
Strip the cable just enough so that the screwed cable gland is tight and
the terminals are relieved of strain. Tightening torque, see chapter 3.1
Product drawing.
NOTE
Tightness and strain relief depend on the cable used.
→ The user must check this.
4.3.2 Connecting cables with terminals
;
Remove the cap from the screwed cable gland.
Remove the cap only in those places where cables are inserted.
;
Insert the line(s) (not included in the standard scope of delivery) into
the terminal box.
;
First connect the "PE" (protective earth) connection.
;
Connect the lines to the corresponding terminals.
;
Connect the thermal overload protector (TOP).
Use a screwdriver to do so.
During the connection work, ensure that no cables splice off.
The terminal strip is equipped with a penetration prevention device.
;
Insert the strands until they meet resistance.
;
Seal the terminal box.
4.3.3 Cable routing
No water may penetrate along the cable in the direction of the cable gland.
NOTE
Damage caused by moisture penetration.
Moisture can penetrate into the terminal box if water is
constantly present at the cable glands.
→ To prevent the constant accumulation of water at the cable
glands, the cable should be routed in a U-shaped loop
(siphon) wherever possible.
→ If this is not possible, a drip edge can be produced by
fitting a cable tie directly in front of the cable gland for example.
Fans installed lying flat
Make sure that the cable is routed in the form of a loop (water trap).
