13 Procedure for Receiving a Replacement Device
5. Insert the lower enclosure lid from above and flip it down. Use the enclosure lid of the
defective inverter for this if there is a label with "transport lid" affixed to the enclosure lid of the
replacement device. Make sure that the ribbon cable of the communication assembly is not
clamped and that the screws must protrude from the lower enclosure lid.
6. Tighten all six screws in the lower enclosure lid with
an Allen key (AF 3) in the order 1 to 6 (torque:
2 Nm ± 0.3 Nm). Make sure that the ribbon cable
of the communication assembly is not clamped. By
tightening the screws in the prescribed order, you
avoid warping the lid, which would keep it from
sealing correctly. Tip: If the screws fall out of the
lower enclosure lid, insert the long screw into the
lower middle hole and the five short screws into the
other holes.
7. Commission the replacement device. Remount the DC load-break switch of the defective
inverter to the replacement device.
8. Configure the replacement device.
9. Replace the replacement device in the communication product.
Shipping the Defective Inverter
1. If necessary, position the upper enclosure lid with
the six screws and conical spring washers on the
enclosure and tighten it using an Allen key (AF 4) in
the order 1 to 6 (torque: 6 Nm ± 0.3 Nm).
2. Insert the lower enclosure lid from above and flip it down. Make sure that the ribbon cable of
the communication assembly is not clamped and that the screws must protrude from the lower
enclosure lid.
