that the line current of the arrangement is in the range of 16 - 75
A, then this arrangement conforms to IEC 61000-3-12 provided
that the short-circuit power Ssc at the connection point of the
customer system to the public power system is greater than or
equal to 120 times the rated output of the arrangement.
It is the responsibility of the installation engineer or operator/
owner of the device to ensure, if necessary after consultation
with the network operator, that this device is only connected to
a connection point with a Ssc value that is greater than or equal
to 120 times the rated output of the arrangement.
CAUTION
Cutting and crushing hazard when removing the device
from the packaging
Blades can be bent
→ Carefully remove the device from its packaging, only
touching the wall ring. Make sure to avoid any shock.
→ Wear safety shoes and cut-resistant safety gloves.
CAUTION

→ 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 whether the data on the type plate agree with 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 crosssection.
We recommend the use of 105°C cables. Ensure that the minimum
cable cross-section is at least
AWG26/0.13 mm².
4.2.4 Residual current operated device
Only universal (type B or B+) RCD protective devices are
permitted. Like frequency inverters, RCD protective devices
cannot provide personal safety while operating the device.
When switching on the power supply of the device, pulsed
charge currents from the capacitors in the integrated EMC filter
can lead to the RCD protective devices triggering without
delay. We recommend residual current devices with a trigger
threshold of 300 mA and delayed triggering (super-resistant,
characteristic K).
4.2.5 Leakage current
For asymmetrical power systems or if a phase fails, the
leakage current can increase to a multiple of the nominal value.
4.2.6 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 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.
4.2.2 Power supply connection, fuse protection
Assignment of conductor cross-sections and the fuse protection required
for them (overload protection only, no device protection).
