3 Installation

3.1. Unpacking Equipment

Remove equipment from packing material and inspect for shipping damage or missing items. It is important to report damage or material shortages to the shipping carrier while a representative is on site.

If concealed damage or material shortages are found at a later time, contact the shipper to make arrangements for inspection and claim filing. Refer to Section 7 in the event it is necessary to return equipment to APC.

CAUTION: Appropriate lifting techniques and safety equipment should be used to remove equipment from packing.

PLEASE RECYCLE: The shipping materials can be recycled. Please save them for later use or dispose accordingly.

3.2. Mechanical Installation

Room / Location

NOTE: The APC Model MX28B DC power plant is to be installed in a room, vault, or similar enclosure that is accessible only to qualified persons in accordance with the NEC or the authority having jurisdiction.

Prior to installation, drawings, floor loading requirements, external alarm points, AC service entrance, and grounding schemes should all be checked and confirmed. If batteries are to be mounted in a room separate from the power plant, careful attention should be paid to battery cable voltage drop effects. Environmental operating temperatures and ventilation/cooling considerations should also be noted, not just for the power system but also for all other equipment that may reside in the power room area.
