Safety and EMC Instructions

Please read the following user manual and the safety instructions carefully before installing the unit or using
the unit.
1-1

Transportation and Storage

Please transport the UPS system only in the original package to protect against shock and impact.
The UPS must be stored in the room where it is ventilated and dry.
1-2

Preparation

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 2 hours for the
UPS system to acclimatize to the environment.
Do not install the UPS system near water or 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.
1-3

Installation

Do not connect appliances or devices which would overload the UPS (e.g. large motor-type equipment)
to the UPS output sockets or terminal.
Do not place cables in such a way that it might cause someone to trip over or need to step over them.
Do not block air vents in the UPS housing. The UPS must be installed in a location with good ventilation.
Ensure enough space on each side for ventilation.
UPS has provided earthed terminal, in the final installed system configuration, equipotential earth
bonding to the external UPS battery cabinets.
The UPS can be installed by qualified maintenance personnel only.
An appropriate disconnect device as short-circuit backup protection should be provided in the building
wiring installation.
An integral single emergency switching device which prevents further supply to the load by the UPS in
any mode of operation should be provided in the building wiring installation.
1
Connect the earth before connecting to the building wiring terminal.
Installation and wiring must be performed in accordance with the local electrical laws and regulations.
UPS designed for linear load, worst case inductive resistive load.

1-4 Operation

Do not disconnect the earth conductor cable on the UPS or the building wiring terminals at any time
since this would cancel the protective earth of the UPS system and of all connected loads.
The UPS system features its own, internal current 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' button and then disconnect the mains.
Ensure that no liquid or other foreign objects can enter the UPS system.
The UPS can be operated by any individual with no previous experience.
