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.

inspection and claim filing. Refer to Section Error! Reference source not found. in the event it is necessary to
return equipment to APC.

equipment from packing.

properly.
2.2. Mechanical Installation
Room / Location
NOTE: The APC dc power plant is to be installed in a room, vault, or similar enclosure accessible only to qualified
persons in accordance with the national and local electrical codes.
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.
Mounting
The Magnum VS 50 and 100 include brackets to mount the system in a standard EIA 19” rack. Install the
power system using hardware designed for the rack. To install a Magnum VS 50 or 100 in a 23-inch rack
use the 23” Mounting Bracket Kit (DCMOPT23RM).
Ventilation
The rectifier modules for this system have fans that provide front-to-rear airflow for internal cooling. The power
system housing should be mounted such that there is free airflow to the front and back of the unit. [Refer to
Section 8.5 for environmental characteristics.] Free airflow should be ensured so that the power system can
provide full power without de-rating.
