The UPS cannot be operated from a mid-point or end-point groundeddelta supply source. With this type of supply source, there is no capability to provide an outputneutral. In no circumstances shall a neutral to ground bonding jumper be installed in the UPS.8. The UPS cabinet is shipped with a debris shield covering the ventilation grill on top of theunit. Do not remove the debris shield until installation is complete. However, remove theshield before operating the UPS. Once the debris shield is removed, do not place objectson the ventilation grill.9. Refer to Section I of this manual for installation instructions.
