1. Important Safety Warning
Please comply with all warnings and operating instructions in this manual strictly. Save this
manual properly and carefully read the following instructions before installing the unit. Do not
operate this unit before reading through all safety information and operating instructions
carefully.
1-1. Transportation
l
Please transport the UPS system only in the original packaging to protect against
shock and impact.
1-2. Preparation
l
Condensation may occur if the UPS system is moved directly from cold to warm
environment. The UPS system must be absolutely dry before being installed. Please
allow at least two hours for the UPS system to acclimate to the environment.
l
Do not install the UPS system near water or in moist environments.
l
Do not install the UPS system where it would be exposed to direct sunlight or near a
heater.
l
Do not block ventilation holes in the UPS housing.
1-3. Installation
To guarantee UPS normal operation, before connecting devices to the UPS, please
verify that ground and neutral lines of the connected devices are not short circuited.
(see Figure 1)
Figure 1
If neutral line and ground line are short circuited, please add isolation transformer
between UPS and devices. (see Figure 2)
