Initial Start-Up con’t
A minimal number of connections are made to the terminal strip (see diagrams
below). If the drive is an enclosed unit with operator devices (start/stop and speed pot)
only the jumper from terminal block TB2-5 to TB2-5A needs to be made- this is a
temporary connection only intended for System Interlock - see Application Safety
a) Regulation Mode: In this procedure, leave jumper in speed regulation
(JP2 = SPD).
