NOTES:
1. Total width, weight, and heat loss are for system line-up excluding battery cabinets.
2. Table does not include battery data; refer tot the installation drawings supplied with
your equipment.
The steps to be followed are:
• Placement of the UPS and associated equipment
• Connection of input power, output power, and control
cables
Installation of UPS equipment must be handled by skilled
technicians and electricians familiar with the special
requirements of high-energy electrical equipment. We
strongly recommend contracting MGE Customer Support
Services for start-up of the installed Comet UPS system. Do
not allow unqualified personnel to handle or operate the
Comet UPS.
Refer to the installation drawings for proper placement and
connections of auxiliary cabinets.
Move the Comet UPS, battery cabinets (if any), and auxiliary
cabinets (if any), to their final location (see Figure 2-1). For
cabinets installed adjacent to each other, alignment is critical
to properly install the mechanical and cable interconnections.
Allow at least 36 inches clearance above all cabinets for
maintenance and cooling.
