Important circuit information
!
Warning
Terminal 63 (pulse enable) and/or terminal 48 (start terminal, contactor control)
must be de–energized before the system is powered–up or down using the
main switch or a line contactor!
!
Warning
If the NE is connected up using a 6–conductor connection (the supply connec-
tion for the electronics power supply is separate from that of the power connec-
tion), then the jumper, included as standard, in connector X181 must be remo-
ved.
Electrical isolation of the line supply from the power circuit of the drive group
via terminals NS1, NS2.
The coil circuit to reliably de–energize the line contactor when an error condition
occurs, can be isolated via terminals NS1, NS2.
The terminals must always be jumpered in operation! The DC link will not
be pre–charged if the connection is missing when the unit is powered–up.
The NS1, NS2 connection may only be switched when terminal 48 is ope-
ned (or simultaneously with terminal 48).
!
Warning
If the power supply is supplied through P500, M500 at connector X181, a
6–conductor connection (electronic power supply connection before the HF
commutating reactor) is not permissible.
