Housing Specifications
The output module RSO ..110
is recommended for motors
up to 22 kW @ 400 V. The
RSO ..110 is designed for use
in applications with high surge
current conditions. Care must
be taken to ensure proper heat-
sinking when the relays are to
be used at high nominal cur-
rents. Adequate electrical con-
nection between relay termi-
nals and cable must be ensured.

For this application RSC-AAM60
must be used. The output
module RSO4025 is selected
according to the Selection Guide.
The
required is 1 K/W, and the
power dissipation is 25 W.
This gives:

Overload protection by ther-
mal relay
Connection to the mains
Since no motor protective
circuitry is included in the
RSC/RSO, the motor must
be protected in the usual
way, i.e. either by a thermal
relay, a PTC-resistor or a
Klixon bimetal temperature
switch near the motor windings.
If short circuit protection is re-
quired, fuses F1 to F3 should
be ultrafast and selected ac-
cording to the load integral
(I
and the motor load.

Transient voltage protection
With an unfiltered main supply,
voltage transient may occur.
Since these transients could
have a high energy content, it
is advisable to use varistors
to protect the output module.
The varistors are already
mounted in the RSO output
module and they are selected
according to the rated opera-
tional voltage.
When motors are running idle,
it not necessary to maintain a
full magnetic field, as is the
case when the motor has to
produce full torque. By lower-
ing the motor voltage, power
losses inside the motor are
also reduced.

When the motor is idle, d1 will
switch the control current from
I
adjusted to a value at which
the motor is still running at full
speed, but at a lower voltage.
Please remark that this type of
phase-angle controlled voltage
reduction, demands additional
filtering to fulfill EMC regulations.
