1 Important Safety Instructions
IMPORTANT! This manual contains important safety instructions that must be followed during the installation and
maintenance of the UPS and batteries. Read this manual thoroughly and the safety and regulatory information,
available at https://www.vertiv.com/ComplianceRegulatoryInfo, before attempting to install, connect to supply, or
operate this UPS.
Comply with all warnings and operating instructions in this manual strictly. Save this manual and carefully read the following
instructions before installing the unit. Do not operate this unit before reading all safety information and operating instructions
carefully.
Transportation
Only transport the UPS system in the original packaging to protect against shock and impact.
Preparation
• Condensation may occur if the UPS system is moved directly from a cold to a warm environment. The UPS
system must be absolutely dry before being installed. Please allow at least two hours for the UPS system to
acclimate the environment.
• Do not install the UPS system near water or in moist environments.
• Do not install the UPS system where it would be exposed to direct sunlight or near a heater.
• Do not block ventilation holes in the UPS housing.
Installation
• Do not connect appliances or devices which would overload the UPS system (e.g. laser printers) to the UPS
output sockets.
• Place cables in such a way that no one can step on or trip over them.
• Do not connect domestic appliances such as hair dryers to UPS output sockets.
• Connect the UPS system only to an earthed shockproof outlet which must be easily accessible and close to the
UPS system.
• Please use only VDE-tested, CE-marked mains cable (e.g. the mains cable of your computer) to connect the UPS
system to the building wiring shockproof outlet.
• Please use only VDE-tested, CE-marked power cables to connect the loads to the UPS system.
• When installing the equipment, ensure that the sum of the leakage current of the UPS and the connected
devices does not exceed 3.5 mA.
Operation
• Do not disconnect the mains cable on the UPS system or the building wiring shockproof outlet during operations
since this would cancel the protective earthing of the UPS system and of all connected loads.
• The UPS system features its own, internal power source (batteries). The UPS output sockets or output terminal
blocks may be electrically live even if the UPS system is not connected to the building wiring outlet.
• In order to fully disconnect the UPS system, first press the OFF/Enter button to disconnect the mains.
• Prevent fluids and foreign objects from entering the inside of the UPS system.
