Installation
SIMODRIVE base line A Start-Up
2-21
Fuse/circuit
Fuse of linear circuit breaker must be used which are designed to protect
breaker
the line supply feeder cables. We recommend the SIEMENS fuse type
listed
below:
●
I
rated
=
16A;
●
I
fuse
0.2s >70A;
●

> 30A;
The order number of the recommended SIEMENS fuse is
:
16AD01 Neoz./B.No.5SE2116
;
Or you can choose SIEMENS circuit breaker: 3RV1031-4BA10.
Isolating
SIMODRIVE base line A can be connected directly to TN-C line supply
transformer
system. The isolating transformer is used as an option in this line supply
type. The connecting diagram is shown in the Fig.2-10. But the isolating
transformer must be used in following cases:
1.
IT line supply system or TT line supply system;
2.
The touchable part in the equipment has potential because of the
unequilibrium load current or harmonic current in three-phase
system in TN line supply
3.
Upstream devices providing protection against hazardous leakage
currents or for fire protection doesn’t comply with the requirements
of DIN EN 50178
