Installation and Connection
English
Let the minimum clearances specified in Figure B.3 on page 234 in order to allow air circulation
for cooling. It is possible to assembly frame sizes A, B and C inverters with IP20 protection
degree (CFW700… 20…) side by side without lateral spacing, i.e., with the D distance presented
in Figure B.3 on page 234 equal to zero.
Do not install heat sensitive components right above the inverter.
ATTENTION!
 When arranging two or more inverters vertically, respect the minimum
clearance A + B (Figure B.3 on page 234) and provide an air deflecting
plate so that the heat rising up from the bottom inverter does not affect the
top inverter.
 Provide conduit for physical separation of the signal, control, and power
conductors (refer to section 3.2 ELECTRICAL INSTALLATION on page 11).
Please refer to Figure B.3 on page 234 for surface and flange mounting data. The inverter
dissipated power at rated condition for surface and flange mounting is presented in Table B.4
on page 216. Remove the drive mounting brackets for flange mounting. The protection degree
of the inverter outside the panel is IP55 for flange mounting. It is necessary to provide proper
seal for the opening where the inverter is installed to ensure the protection degree of the panel.
Example: sealing with silicone.
Please refer to Figure A.4 on page 204 for more details on the access to the control and
power terminals.
