WARNING
The instructions in this chapter are not addressed to a normal operator but to a specialized technician, authorised
to work only if he uses the Individual Protective Gear mentioned in Chapter 4.
6.1 Safety rules and regulations
Before starting installation please read and apply the following:
1. Attention: equipment with a high sneak current, it is indispensable to earth it before connecting the power supply. It
is necessary to ensure that the distribution panel, to which the UPS is to be connected, has a secure connection to the
earth circuit and adequate protection as required by law.
2. Only the fixed type of the UPS Archimod® units must be installed with a thermal circuit breaker upstream. Connection
of the unit to the mains using a traditional plug is not allowed.
3. The mains supply panel or disconnecting device, must be installed near the equipment and easy to access.
4. A warning label must be affixed on all mains supply isolating switches installed far away from the UPS area to
remind assistance personnel that the circuit is connected to a UPS. The label must give the following message (or the
equivalent):
ISOLATE THE UPS UNIT BEFORE WORKING ON THIS CIRCUIT!
6.2 Electrical connections
The electrical connection of the UPS to the switchboard is part of the installation and usually is not done by the UPS
manufacturer; therefore the following indications are purely an example and the actual electrical connections must be
done in accordance with local standards.
Once the UPS has been removed from the packaging and positioned in its final place of installation, the authorised
technician can start its installation.
ATTENTION
The type and cross section of the connecting cables must be chosen according to their operating current and laying
must be as established by existing laws; this is the responsibility of the installer. The UPS input current and output
power are given in paragraph 3.4 and the battery current in Table 7.
INDICATION
In the TABLES chapter, tables 1 to 6 give indications about sizing of cables, fuses, circuit breakers and RCDs as well as an example
of cable sizing if unipolar cables are used without a sheath, in PVC and laid in a pipe above ground.
