y The UPS adopts top wiring. Please leave adequate space on the top of the UPS to allow
cable entry. If you use the Delta external maintenance bypass cabinet (optional), top
wiring and bottom wiring are both applicable.
y Ensure that the installation area is big enough for maintenance and ventilation. Since
the UPS adopts the design of air inlet at the front and air outlet at the rear and external
battery cabinets must be placed next to the UPS, we suggest that you:
1. Keep a distance of 100cm from the front of the UPS for maintenance and ventilation.
2. Keep a distance of at least 35cm from the back of the UPS for ventilation, or at least
50cm for maintenance.
3. Keep a distance of 50cm from the top of the UPS for maintenance, wiring and
ventilation.
