Maximum cable length for PTC thermistor sensor circuit:
Cross-section 2.5 mm²
Cross-section 1.5 mm²
Cross-section 0.5 mm²
The PTC input can be used for monitoring motors in the Ex-Zone. The inverter itself must not
be installed in the Ex-Zone.
The PTC thermistor evaluation function can be deactivated by an internal switch. For this
reason, carry out the test described in section "Testing the PTC thermistor shutdown
function" (Page 141). If the result of the test is negative, contact the Service Center for advice.

If you connect several inverters in parallel, the technical data are multiplied according to the
number of systems. The water flowrate for type 2T 6 A‑7 5 69 4‑925 with four inverter systems
is e.g. 4×2000 l/h.
The water-cooled units BG SW2 and SW21 have the same cabinet width as the air-cooled units.
