Installation position and dimensions
The M200D motor starter is suitable for the following installation positions on a flat surface:
Figure 4-1
Installation positions: horizontal, vertical, flat; must not be positioned as shown on the right
Please note the following external dimensions when mounting the motor starter:
HxWxD: Approx. 294 x 215 x 162 mm

Derating
What is derating?
Derating allows devices to be used even in harsh operating conditions by selectively
restricting the output capacity.
Derating factors
When M200D motor starters are operated under harsh ambient conditions, the following
factors must be taken into account:
●
Ambient temperature T
a
:
–
The ambient temperature T
a
is the temperature of the air surrounding the motor starter
enclosure.
The lower the maximum ambient temperature T
a
, the higher the current load on the
motor starter can be.
–
The installation position affects how quickly the motor starter cools.
●
Absolute current load:
–
The lower the current flowing through the motor starter, the lower the power loss
(= heat) inside the device. If a small amount of self-heating occurs, the ambient
temperature T
a
can be higher.
–
In the case of soft starters in which the soft start function has been deactivated, the
maximum permissible rated operating current I
e
is restricted to 9
A (≡ electronic direct
starter; sDSte).
●
Installation altitude
If the installation altitude exceeds 1,000 m, a reduction to the rated operating current is
required for thermal purposes. For more details, refer to the technical specifications:
