Line to Line from 90VAC to 600 VAC (UL) (520 VAC for CE). In UL installations the lines may be floating (such as a delta). If any lines are tied to an earth (such as a corner grounded delta), see the Line to Neutral installation limits. In CE compliant installations, the lines must be neutral (earth) referenced at less than 300 VACL-N

FUSE RECOMMENDATIONS

Keep the fuses close to the power source (obey local and national code requirements).

For selecting fuses and circuit breakers, use the following criteria:

•Select current interrupt capacity based on the installation category and fault current capability.

•Select over-current protection with a time delay.

•The voltage rating should be sufficient for the input voltage applied.

•Provide overcurrent protection and disconnecting means to protect the wiring. For DC installations, external circuit protection must be provided. Suggested: 0.5 A, time delay fuses.

•The earth connection is required for electromagnetic compatibility (EMC) and is not a protective earth ground.

WIRING NOTES

•Use 14-24 gauge wire for all connections.

•When tightening terminals, ensure that the correct torque is applied: 3.5 - 4.4 in·lb (0.4-0.5 N·m).
