To use the inverter outside of an enclosure in the environment of pollution degree 2, fix a fan cover with fan cover fixing
screws enclosed.
Note, the protection structure of the Inverter units is considered to be an IP00.
∗
On the input and output of the inverter, use cables of the type and size set forth in EN60204 Appendix C.
∗
The operating capacity of the relay outputs (terminal symbols A, B, C) should be 30VDC, 0.3A. (Relay outputs are
basically isolated from the inverter internal circuit.)
∗
Control circuit terminals on
page 4
are safely isolated from the main circuit.
