ADV200 SP • Quick start up guide - Specification and installation 93
10.2 SPDs (surge protection devices)
Note! SPDs must be installed in the immediate vicinity of the drive and with an overall connection cable length of less than
50 cm (out and back < 50 cm).
The ADV200-SP has been designed to be connected to a power supply with category III overvoltage (to ground) and 4
kV pulse voltage.
On AC side the overvoltage protection devices must be used to ensure that the ADV200-SP drive cannot be damaged.
The higher level of protection of the 3kV surge arrester guarantees an adequate level of protection, even considering
the increase in overvoltage at the drive due to the parasitic inductance of the surge arrester’s connection cable.
10.2.1 DC-side SPD devices
Maximum operating voltage of the SPD ������������� 800Vdc (maxVacuum panel voltage) *1.25
Type of surge arrester according to EN 61643-11 ������ T2
Nominal discharge current (8/20us) ���������������� 20kA (or higher depending on the electrocution risk level)
Maximum discharge current (8/20us) �������������� 40kA (or higher depending on the electrocution risk level)
Configuration ��������������������������������� Y
Test class ����������������������������������� II (suitable for protection against indirect discharges)
C-D surge arrester ����������������������������� varistor
C-PE and D-PE arresters ������������������������� gas spark gap
(or a different technology provided that it is expressly indicated for operation
on IT networks. The gas spark gap ensures galvanic insulation to ground and
therefore does not affect the operation of the insulation monitor).
Superior level of protection L-PE ������������������ ≤3kV
Response time ������������������������������� ≤25ns
10.2.2 AC-side SPD devices
Continuous operating voltage SPD ����������������� 480Vac*1.1 (for IT systems)
277Vac*1.1 (for TT and TN systems)
Type of surge arrester according to EN 61643-11 ������ T2
Nominal discharge current (8/20us) ���������������� 20kA (or higher depending on the electrocution risk level)
Maximum discharge current (8/20us) �������������� 40kA (or higher depending on the electrocution risk level)
Configuration ��������������������������������� Y
Test class ����������������������������������� II (suitable for protection against indirect discharges)
L-PE surge arrester ���������������������������� varistor (or a different technology provided that it is expressly indicated for
operation on IT networks.)
Superior level of protection L-PE ������������������ ≤3kV
Response time ������������������������������� ≤25ns
