Inverter Mounting | and Installation |
|
|
This section includes tables for 200V class and 400V class inverters (on the next page). The following notes will help you read the tables in this section:
•Locate the row corresponding to the motor size and particular inverter in your application. The maximum motor current determines the recommended wire sizes.
•The length column specifies that some inverters can optionally use a smaller wire gauge if the wires are shorter than 10m and the inverter is located in an enclosure.
•Power Lines columns include wires connecting to terminals [R, S, T, U, V, W, P, PD, and N]. Only power input and motor leads will be fused: [R, S, T, U, V, and W]. The breaker ratings
•The chassis ground columns list the
•The optional external braking resistor wiring only applies to a few models that have a built- in braking unit. The other models use an optional external braking unit.
•Parallel wires increase effective wire gauge, and are denoted by “” in the tables.
•Signal Lines, not listed in these tables, connect to the removable logic connector. The recom- mended wire gauge for all wiring to the logic connector is 28 AWG (0.75 mm2). Be sure to use shielded wire for any analog signals.
