• Mains r.m.s. current: ^ 3-4
With insulated neutral
(IT mains)
Possible, if the controller is protected in the event of an
earth fault in the supplying mains.
• Possible, if appropriate earth fault detections are
available and
• the controller is separated from the mains
immediately.
Safe operation in the event of an earth fault at the
inverter output cannot be guaranteed.
With earthed phase Operation is only possible with one variant Contact Lenze
DC-supply via + UG/-UG The DC voltage must be symmetrical to PE. The controller will be destroyed when grounding + UG or
-U
G.
4.2.5 Interaction with compensation equipment
• The controllers take up a very low fundamental reactive power from the supplying AC mains.
Therefore compensation is not necessary.
• If the controllers are operated at mains with compensation, this equipment must be used with
chokes.
– For this, contact the supplier of the compensation equipment.
4.2.6 Specification for all cables used
• The cables used must comply with the required approvals of the application site
(e.g.UL).
• The prescribed minimum cross-sections of PE conductors must be maintained in any case.
The cross-section of the PE conductor must be at least as large as the cross-section of the
power connections.
• The shielding quality of a cable is determined by
– a good shield connection
– a low shield resistance
Only use shields with tin-plated or nickel-plated copper braids!
Shields of steel braid are not suitable.
– For the overlapping degree of the screen braid:
A min. of 70 % to 80 % with an overlapping angle of 90°.
