The bridge (jumper) between Termi-
nal 37 and 24 V DC must be re-
moved. Cutting or breaking the
jumper is not sufficient. Remove it
entirely to avoid short-circuiting. See
jumper on illustration.
Connect terminal 37 to 24 V DC by a
short-circuit protected cable. The 24
V DC voltage supply must be inter-
ruptible by an EN954-1 Category 3
circuit interrupt device. If the inter-
rupt device and the frequency con-
verter are placed in the same instal-
