5. Once the installation is complete, use a 3/4 inch wrench to screw down the UPS leveling feet located next to the four
casters, until the unit is no longer resting on the casters.
6. The UPS generates and can radiate radio-frequency energy during operation. Although RFI noise filters are installed
inside of the unit, there is no guarantee that the UPS will not influence some sensitive devices that are operating near
by. If such interference is experienced, the UPS should be installed farther away from the affected equipment and/or
powered from a different source than that of the affected equipment.
7. It is the responsibility of the installer of this equipment to provide a suitable disconnect for the Control Panel supplying
power to this equipment.
This disconnect must:
Be suitable for the Voltage and Full Load Ampere Rating of all downstream equipment supplied by the Panel;
The supply disconnecting device shall be one of the following types:
• Switch-disconnector, with or without fuses, in accordance with IEC 60947-3, utilization category AC-23B or DC-
23B
• As above, except one that has an auxiliary contact that in all cases causes switching devices to break the load
circuit before the opening of the main contacts of the disconnector.
• A circuit breaker suitable as an isolation device per IEC 60947-2
• Any other switching device in accordance with an IEC product standard that also meets the isolation requirements
of IEC 60947-1 and is appropriate for on-load switching of motors or other inductive loads;
Be approved for use as a disconnect for the country in which this equipment is installed.
Be provided with a Lock Out Tag Out capability in the Off (Down) position.
8. Allow 5 minutes after power is removed for internal capacitors to fully discharge before attempting to service the unit.
9. The user should provide output over-current protection for hardwired UPS systems. See Appendix A - "Specifications"
for the device rating.
10. After ensuring that all power sources are turned off and isolated in accordance with established lockout/tagout proce-
dures, connect the power source wiring of the correct voltage to the input terminals of the UPS.
11. The end user must supply suitable strain relief for the power cord and the cord must extend a distance of 1/2 diameter
beyond the clamp.
12. Connect the output terminals of the UPS to the load in line with local wiring regulations. Size the branch circuit con-
ductors in accordance with NEC Table 310.16.
13. Conductor Routing and Grounding
a. Use separate metal conduits for routing the input power, output power, and control circuits.
b. Follow the wire size and tightening torque specifications listed in Section 7.4.
c. Always ground the unit to reduce the potential for electrical shock and to help reduce electrical noise.
d. A separate ground cable should be run inside the conduit with the input power, output power, and control circuits.
