Assembly instructions
–
Always install the device vertically in the control cabinet (mains supply line [X9] underneath).
–
Maintain minimum distances and mounting clearance to guarantee sufficient air flow. The ambient
air in the control cabinet must be able to flow through the device from bottom to top without
hindrance. Detailed information about the required mounting clearances and any power reduction
that may be necessary as a function of the ambient temperature
–
Take into account the required clearance for the wiring (connecting cables of the device must be
routed from above, from below and from the front).
–
Do not mount any temperature-sensitive components near the device. The device can become very
hot during operation (switch-off temperature of the temperature monitoring function
è
Technical
data).
–
When mounting on an H-rail: use a DIN mounting rail TH 35-7.5 or TH 35-15 in accordance with
EN 60715.
–
When mounting on the backwall of the control cabinet: screw the device on vertically and flat to the
mounting surface.
