Then shutdown the device, disconnect it and keep the UPS and the battery cabinet(s) in their original
packaging, noting the new battery charge date on the respective labels.
Do not store the unit where the ambient temperature exceeds 40ºC or falls below -20ºC, as this may
deteriorate the electrical characteristics of the batteries.
4.2.3
Transport to location.
All UPS devices have castors to facilitate their transport to their final location. It is important to abide by the
approximate weight requirements indicated in tables 5 and 6 both with respect to the site itself and the
installation means (floor, hoist, lift, stairs, etc.).
4.2.4
Location.
The Safety Instructions indicate that a minimum of 25cm clearance should be left around the equipment for
ventilation purposes. However an additional 75 cm is recommended to facilitate maintenance operations or
technical assistance in the event of breakdown (see figures 12 and 13).
The UPS may be put in any place as long as the Safety Instruction requirements are fulfilled and the weight
requirements indicated in table 7 and 8 are complied with.
The UPS includes 2 levelling components (PB) located near the front castors, which immobilise the unit
once in place.
Open the front door (PF) of the cabinet and proceed as follows:
- Lower the feet (PB) by hand by turning them anticlockwise until they touch the floor, and then, using
a spanner, continue loosening until the castors are raised off the floor by a maximum of 0.5 cm,
ensuring that it is level.
-Close the door (PF).
4.3
Connections.
4.3.1
Mains terminals (X1 to X4).
As this is a device with class I protection against electric shocks, it is essential to install a protective
earth conductor (earth connection ( )). Connect the conductor to the terminal (X5), before connecting the
power supply to the UPS input.
In accordance with safety standard EN-IEC 62040-1, the installation has to be provided with a “Backfeed
protection” system.
For example a contactor, which will prevent the appearance of voltage or dangerous energy in the input mains
during a mains fault (see figure 14 and comply with the “Backfeed protection” wiring diagram if the equipment
has single or three phase input)
There can be no bypass in the line that goes from the “Backfeed protection” to the UPS, as this would
infringe on standard safety requirements.
Warning labels should be placed on all primary power switches installed in places that are not in the vicinity of
the device to alert the electrical maintenance personnel of the presence of a UPS in the circuit.
The label will bear the following or an equivalent text:
Before working on this circuit :
- Isolate the Uninterruptible Power Supply (UPS).
- Then check for Hazardous Voltage between all terminals including the protective earth.
Risk of Voltage Backfeed.
