2.3.3. POWER TERMINALS / BARS
DESCRIPTION
41/R – 42/S – 43/T
Inputs for three-phase supply (the phase sequence is not important)
44/U – 45/V – 46/W
Three-phase motor outputs
47/+
Link to the DC voltage positive pole. It can be used for
-DC voltage supply;
- DC reactor;
-
the external braking resistor and the external braking unit (for the drive models which are NOT
provided with terminal
50/+
dedicated to the external braking resistor)
- the external braking unit.
47/D
When fitted, link to the positive pole of the continuous AC rectified voltage. It can be used for the
DC reactor—if no DC reactor is used, terminal 47/D must be short-circuited to terminal
47/+
using a cable/bar having the same cross-section as the cables used for pow
er supply; factory
setting).
48/B
When available, it can be used to connect the IGBT brake for braking resistors.
49/–
Link to the negative pole of the DC voltage. It can be used for DC power supply and the external
braking unit (for the drive models which are NOT provided with terminal
52/- dedicated to the
external braking unit).
50/+
When available, it can be used to connect the positive pole of the DC voltage to be used for the
external braking resistor only.

S05 (2T) Terminal board:
CAUTION
Connection bars
47D
and
47+
are short-circuited as a factory setting. The DC choke,
if any, shall be linked between bars
47D
and
47+
after removing the short-circuit.
CAUTION
If DC supply is required and if an external
braking resistor is to be installed, remove
the short-circuit between
47/D
and
47/+
and use terminal
47/+
.
CAUTION
Use terminals
47/+
and
48/B
if an external braking resistor is to be installed.
