Horizontal installation position of devices i950, i750 i700, 9400, 8400TL

Question:

Can servo inverters i950, i750, i700, 9400 and 8400TL also be used in a horizontal installation position?

Answer:
According associated installation instructions, the installation position for the following device series is vertical alignment default:

Servo inverter i950 (in general, exceptions see below)
Servo inverter i750
Servo-Inverter i700
Servo-Drives 9400
Servo-Inverter 8400TL

background:

The trend towards ever more compact appliances requires a sophisticated concept for dissipating the heat generated inside the appliance. The design of the appliances takes these requirements into account right down to the component level. component level in order to prevent the components in the inverter from overheating.
Different installation positions have altered flow conditions which in turn can lead to local overheating (thermal hotspots) and premature device failure.

i950: additional installation positions:

servo inverter i950 0.55kW...15kW (400V) and
Servoumrichter i950 0,37kW...5.5kW (230V)

Two additional possible installation positions have been verified and approved for these devices:

Mounted horizontally aligned on the back wall of the control cabinet, instead of vertically, i.e. rotated +/- 90 degrees to the side.
Mounted with the back of the device on the base plate so that the front is facing upwards.

For both installation situations, the technical data and approvals apply as for standard installation (vertical), as described in the current project planning manual for the i950.
Significantly higher temperatures can occur on the front of the device / the feedback module than with the standard installation position.
The device fans are controlled in such a way that no impermissibly high temperatures can occur inside the device.

In future, the additional installation positions will also be described in the installation instructions and the project planning manual.
