3.5 Additional electrical specifications
Ecosine max passive harmonic filters general electrical specifications refer to operating altitudes up to
2000m (6600ft) above sea level.
Operation between 2000m and 4000m (6600ft and 13123ft) requires a derating for current and clear-
ance according to IEC 60664-1, hereafter enclosed:
Table 19 Altitude correction factors
Remark:
Do not use ecosine max passive harmonic filters in altitudes above 4000m without consulting
Schaffner first.
3.6 Cable cross-section requirement
3.6.1 Power terminals
All power terminal of ecosine max filters are busbar connection, with designation -99.
The cable cross-section must be selected according the rated filter input current, the maximum cur-
rent, the environment and other special requirement of the application. It should be either a stranded
copper wire cable with a temperature rating of
≥
75°C or higher or a busbar not smaller than the termi-
nal dimensions of the filter. Recommended cable cross-section is given in Table 20, busbar terminal
dimensions are given in Figure 4. The customer is fully responsible to define the most appropriate con-
ductor type according to the application and ensure a proper connection of the filter.
