Emc Emission - Danfoss VLT 2800 Series Operating Instructions Manual

inforced/double insulation and associated testing pur-
suant to EN 50 178.
1. Transformer and optical separation in voltage
supply.
2. Optical insulation between Basic Motor Con-
trol and control card.
3. Insulation between the control card and the
power part.
4. Relay contacts and terminals relating to other
circuits on the control card.
PELV insulation of the control card is guaranteed un-
der the following conditions:
- TT network with maximum 300 Vrms be-
tween phase and earth.

- TN network with maximum 300 Vrms be-
tween phase and earth.
- IT network with maximum 400 Vrms between
phase and earth.
In order to maintain PELV all connections made to the
control terminals must be PELV, e.g. thermistor must
be reinforced/double insulated.

EMC emission

The following system results are achieved on a system
consisting of a VLT Series 2800 with screened/arm-
oured control cable, control box with potentiometer,
screened/armoured motor cable and screened/arm-
oured brake cable as well as an LCP2 with cable.
