Install the components into the enclosure as described in chapter
frame size R7 with bottom exit
• Install the enclosure roof plate directly onto the enclosure frame without spacers
and a wire mesh (no air outlet through the roof).
• Do not install ventilation gratings and an EMC fan-and-filter unit on the enclosure
door (no air inlet through the door).
• Fasten the back mounting plate at the back of the enclosure frame without
moving it 70 mm inwards from the back vertical profile. This is needed for
allowing air to enter the front grating of the drive module as the front door of the
enclosure has no gratings.
• Fasten three air baffles that face the enclosure door:
- one at the front top of the drive module
- one at the left-hand side of the drive module
- one at the right-hand side of the drive module.
