4.2 Installation conditions for motor starters
Observe the following installation conditions when using an ET 200SP motor starter:
● Mounting position
You can install the motor starter vertically, horizontally or on its back. The mounting
position refers to the alignment of the mounting rail The maximum permissible ambient
temperature range depends on the mounting position:
– Up to 60° C: Horizontal mounting position
– Up to 50° C: Vertical and recumbent mounting position
Also take into account the current carrying capacity of the ET 200SP components.
In the case of a vertical mounting position, use end retainers "8WA1808" at both ends of
the ET 200SP station:
● Mounting rail
Use one of the following mounting rails:
– 35x15 mm DIN rail in accordance with DIN EN 60715
– 35x7.5 mm DIN rail in accordance with DIN EN 60715
– SIMATIC S7 mounting rail
● Current carrying capacity of the ET 200SP station
Current carrying capacity refers to the current load via the power bus and the infeed bus
of the ET 200SP station.
Depending on the ambient conditions and mounting position, you have to take account of the
fan unit or additional mechanical fixings.
Mechanical brackets
Use the mechanical brackets in the following situations:
● When using a 15 mm mounting rail
● With a vertical mounting position
● For applications according to shipbuilding standards in all mounting positions with 7.5 mm
and 15 mm mounting rails
Designing interference-free motor starters
For interference-free operation of the ET 200SP station in accordance with standard
IEC 60947-4-2, use a dummy module before the first motor starter.
Note the following mounting rules:
Use the following dummy module on the standard mounting rail between the previous
module and the SIMATIC ET 200SP motor starter:
BU cover 15 mm: 6ES7133-6CV15-1AM0 with BaseUnit 6ES7193-6BP00-0BA0
For operation of the ET 200SP station with an unused BaseUnit, a cover must be provided
for the open BaseUnit plug contacts (power connector, power bus connector, and backplane
bus connector).
The cover protects the plug contacts against dirt. The BU cover can be ordered as an
accessory.
