Remove the side parts which prevent the transpallet to damage the UPS.
Unload the UPS from the pallet.
It is recommended to store the original UPS packaging for future needs.
The equipment may only be installed and commissioned by authorized LEGRAND
UPS Technical Service Sta or authorized LEGRAND distributor Technical Service Sta.
When the UPS is brought from a cold place to a warmer place, humidity of the air may
condensate in it. In this case, wait minimum for 2 (two) hours before powering the UPS.
KEOR T must be protected from voltage surge with devices that are suited to the installation; the
mains voltage surge must be limited to 2kV. These protective devices must be sized to take into
account all the installation parameters (geographical position whether or not there is a lightning
rod, whether or not there are other suppressors in the electrical installation, etc )
Do not connect the output neutral to the protective ground or protective bonding (except the
TNCOption). Keor T does not modify the neutral arrangements of the system; the use of an isola-
tion transformer is required should it be necessary to modify the neutral arrangements down-
stream Keor T.
Power cables and communication cables shall be installed on trays according to the standards
of the country.
