Operating instructions
D3G146-AH50-11
Translation of the original operating instructions
→ Connect the device only to circuits that can be switched off
using an all-pole disconnecting switch.
→ When working on the device, you must switch off the
system/machine in which the device is installed and secure
it from being switched on again.
NOTE
Interferences and failures are possible
Maintain a distance to the power supply line when routing the
control lines of the device.
→ Ensure a sufficiently large clearance.
Recommendation: clearance > 10 cm (separate cable
routing)
NOTE
Water penetration into leads or wires
Water enters at the cable end on the customers side and can
damage the device.
→ Make sure that the cable end is connected 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 that the data on the type plate match the connection data.
;
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 60335
Compliance with the resistance specifications as per EN 60335 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.
4.2.2 Locked-rotor protection
Due to the locked-rotor protection, the start-up current (LRA) is
equal to or less than the nominal current (FLA).
4.3 Connection of the cables
External leads are brought out of device.
;
First connect the "PE" (protective earth) connection.
●
Connect the lines according to your application. When doing so,
observe chapter 4.4 Connection screen.
