In order to access this fuse and configure the Topaz 100 input for 240VAC, the units cover must be removed. This
is accomplished by removing the (6) screws that hold the cover in place. These screws will be required when re-
securing the cover, once the Topaz 100 is properly configured.
4. Verify that the output voltage required by the load is compatible with the output jumper configuration. If not,
change output jumper configuration accordingly.
5. Once configured properly and making sure power is OFF, connect the input source voltage wires to the
terminals provided. Verify connections are tight and energize the unit (Refer to TERMINAL BLOCK WIRE
RANGE / TORQUE SPECIFICATION Table 2-1).
6. Verify that the output voltage is within nominal specifications.
7. Turn the power OFF, connected the output (load) wires to the terminals provided. Verify connections are tight,
replace the units cover and re-energize the unit (Refer to TERMINAL BLOCK WIRE RANGE / TORQUE SPECI-
FICATION Table 2-1).
8. 1800va to 7500va models configured for an input of 240VAC or 480VAC require a 2 pole input circuit breaker
as specified on page 2-4, provided by the customer.
9. All models rated greater than 1000VA require input circuit breaker as specified on page 2-4, provided by the
customer.
