Specifications
3Ø, 600 VAC can be achieved via the auto-transformer
module. This module provides the necessary electronics
to convert the 3Ø, 480 VAC inut voltage to a 3Ø, 600 VAC
output voltage.
The 3Ø, 600 VAC ouput voltage cannot be achieved unless
the voltage selector switch (Figure 28) is placed in the 3Ø,
480/277 position.

3. After drilling, make sure all shavings and debris have
been removed from the enclosure.
4. Install customer supplied conduit, fittings and bushing
through enclosure hole opening.
5. Next, route the customer supplied 5 wires through the
straight conduit fitting.
6. Connect the 3 load wires (RED, and )
to the load side (bottom) of the circuit breaker, T1, T2
and T3 respectively. Reference Figure 30
