OPTIONAL STEP-UP TRANSFORMER

The INV series can provide a 220VAC or 240VAC output with the addition of an external
transformer chassis. With this option a second rack mountable chassis is provided to convert the
standard 120VAC output to the higher value. In addition, the bypass option can also be included
with the external transformer. A block diagram of the optional transformer configurations is
provided in figure 2-4. Special units may vary and will be identified by a four digit engineering
code. Interconnecting wiring should be rated at 250VAC or better. Ring lugs are recommended
for all connections.
