4.1 Standard mounting position
The device is mounted on standard mounting rails according to EN 60715. The device must
be mounted vertically in such a way that the input terminals and the output terminals are at
the bottom to ensure correct cooling.
A clearance of at least 50 mm should be maintained above and below the device (maximum
depth of the cable duct, 50 mm).
No space is required at the side.
Ballast device 6EP1566-3AA00 must be mounted so that it is to the right of the PSU400M
24 V/20 A power supply.
When mounting the PSU400M together with the ballast device, the same derating curves
apply.
