Translation of the original operating instructions
NOTE
Water ingress into wires or cables
Water ingress at the customer end of the cable can damage the
device.
→ Make sure the end of the cable is connected in a dry
environment.
Only connect the device to circuits that can be switched off with
an all-pole disconnection switch.
4.2.1 Requirements
;
Check whether the information on the nameplate matches the
connection data.
;
Before connecting the device, make sure the power supply matches
the device voltage.
;
Only use cables designed for the current level indicated on the
nameplate.
For determining the cross-section, note the sizing criteria according
to EN 61800-5-1. The protective earth must have a cross-section
equal to or greater than that of the phase conductor.
We recommend the use of 105 °C cables. Ensure that the minimum
cable cross-section is at least
AWG 26 / 0.13 mm².
;
Note the following when routing the cables:
For permanently installed lines, the bending radius must be at least
four times the outside diameter of the cable.
For movable lines, the bending radius must be at least 15 times the
outside diameter of the cable.
Protective earth contact resistance according to EN 61800-5-1
Compliance with the resistance specifications according to EN 61800-5-
1 for the protective earth connection circuit must be verified in the end
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 Reactive currents
Because of the EMC filter integrated for compliance with EMC
limits (interference emission and immunity to interference),
reactive currents can be measured in the supply line even
when the motor is at a standstill and the line voltage is switched
on.
●
The values are typically in the range < 250 mA
●
At the same time, the effective power in this operating state
(operational readiness) is typically < 4 W.
4.2.3 Residual current circuit breaker (RCCB)
If the use of a residual current device (RCD) is required in your
installation, only AC/DC-sensitive residual current devices
(type B or B+) are permissible. As with variable frequency
drives, residual current devices cannot provide personal safety
while operating the device. When the device power supply is
switched on, pulsed charging currents from the capacitors in the
integrated EMC filter can lead to the instant tripping of residual
current devices. We recommend the use of residual current
circuit breakers (RCCB) with a trip threshold of 300 mA and
delayed tripping (super-resistant, characteristic K).
4.2.4 Basic insulation of the alarm relay
As the alarm relay only has basic insulation (for TN/TT
systems) or functional insulation (for phase-conductor-grounded
networks) with respect to the supply voltage, and not double
insulation like the rest of the interface, corresponding precautions
must be taken for industrial applications (EN 61800-5-1).
→ The voltage switched by the alarm relay (e.g. 24 VDC)
must then have no electrical connection to the 10 V output, 0-
10 V control input and GND (electrically isolated interface).
4.2.5 Locked-rotor protection
Due to the locked-rotor protection, the starting current (LRA) is
equal to or less than the nominal current (FLA).
4.3 Plug connection
4.3.1 Making supply connections
;
Check your connector's pin assignment.
;
Connect the built-in connector with the mating connector.
;
Ensure that the connector is properly engaged.
