4.4.3 Checks After Installation
After installing the UPS Auxiliary Cabinet, make the following checks:
1. Ensure that all power and control wires have been properly connected and securely
tightened.
2. Check the rating on the upstream protective devices, and make certain that they are
compatible with the UPS Auxiliary Cabinet requirements.
3. Verify that the input voltage to the HA32C/D/E UPS Auxiliary Cabinet is that shown
on the HA32C/D/E nameplate, located inside the door of the UPS Auxiliary Cabinet.
4. Verify that the output voltage rating of the HA32C/D/E UPS Auxiliary Cabinet is
compatible with the UPS input voltage requirements (UPS main ac input and/or
bypass ac input). Check both nameplates.
