3.2.2 UPS System Power Wiring Preparation
The UPS system installation must meet the following guidelines:
•
The system must be installed on a level floor suitable for computer or electronic equipment.
•
The system must be installed in a temperature and humidity controlled indoor area free of conductive
contaminants.
Failure to follow guidelines may void your warranty.
The UPS equipment operating environment must meet the weight requirements shown in Table 3-1 and the
size requirements shown in Figure 3-1. Dimensions are in millimetres (inches).
WARNING
•
HIGH TOUCH CURRENT EARTH CONNECTION ESSENTIAL BEFORE CONNECTING SUPPLY.
As a result of the connected loads high leakage current is possible. Connection of the earth
(ground) is required for proper product operation. Do not check UPS operation by removal of
the Earth (ground) connection.
•
The UPS unit is not suitable for IT and corner-earthed power distribution systems.
CAUTION
If battery systems are located in the same room as the UPS, the battery manufacturer's
environmental requirements should be followed if they are more stringent than the UPS
requirements. Operating temperatures above the recommended range will result in decreased
battery life and performance, and may reduce or void the battery warranty.
The UPS ventilation requirements are shown in Table 3-4.
