Note
The supply voltage at terminals U and V must:
be supplied via an isolating transformer (300 VA, basic isolation in accordance with EN 50
178 or VDE 0550) for non-HEIDENHAIN inverters and regenerative HEIDENHAIN inverter
systems.
There is no need for an isolating transformer if non-regenerative HEIDENHAIN inverter
systems are used.
DANGER
Do not ground this isolating transformer on the secondary side!
The isolating transformer decouples the dc-link voltage from ground. Grounding the isolating
transformer on the secondary side leads to an addition of the dc-link voltage and the supply
voltage. This would overload and thus destroy the UV 105.
the conductor bars (for HEIDENHAIN inverter systems).
a cable which is connected instead of the conductor bar (for non-HEIDENHAIN inverter
systems).
Operation with HEIDENHAIN inverters:
For the NC to be able to evaluate the status signals of the compact inverters or the power
supply units, connector X69 must be connected by ribbon cable with X69 of the UV 105.
Operation with non-HEIDENHAIN inverters:
Since status signals from non-HEIDENHAIN inverters are not available or are not
compatible to HEIDENHAIN systems, the adapter (Id. Nr. 349 211-01) must be connected
to X69 on the UV 105.
