Testing
h
That the data on the nameplate (data, load current) corresponds to the data
for the plant.
h
That the rotary electrical field has clockwise phasing if the economy circuit
configuration is used.
h
That the configuration of the analog inputs, for example, corresponds to the
wiring.
h
The analog input for the setpoint specification only needs to be connected
to the master. The slave receives its information via the 1:1 patch cable.
However, the slave power controller can be disconnected separately by
means of its own inhibit input.
Load connec-
tion
h
The electronic switch (2 anti-parallel thyristors) is located between the U1
and U2 terminals.
h
Where possible, load cables and cables for control inputs should be routed
so that they are isolated.
h
Connect the mains voltage - thyristor power controller - load in accordance
with the connection diagram and check.
Phasing The voltage supply of the control electronics and the load voltage
must have the same phase.
Control inputs The terminal strips for control connections (inputs and outputs) have been laid
out for safe isolation from the mains voltage (SELV). To prevent the safe isola-
tion from being impaired, ensure that all connected current circuits are also
safely isolated. The required auxiliary supplies must be SELV voltages.
The ground terminals X2_2/11
or X2_1/6
of the master and slave must be con-
nected to one another.
2.1.1 Environmental influences
Incorrect use The device is not suitable for installation in potentially explosive areas.
Mounting site The power controller must be installed in a fire-proof control cabinet.
The cabinet should be vibration-free, free from aggressive media, and free
from dust to prevent the ventilation slots from becoming blocked.
Climatic
conditions - Relative humidity: 5 to 85 %, no condensation (3K3 according to EN 60721)
- Ambient temperature range: 0 to 45 °C (3K3 according to EN 60721-3-3)
- Storage temperature range: -30 to +70 °C class 1K5
Avoid additional
sources of heat - Ensure that the ambient temperature at the installation site is not increased
by other sources of heat or heat accumulation.
- Do not mount the power controller too close to the heating process (fur-
nace)
- Avoid direct sunlight.
Power loss Occurs as waste heat on the cooling body of the master and slave device and
