Descriptions of formwork shall be deemed to
include use and waste only (except where
described as "left in" or "permanent"), for fitting
together in the required forms, wedging,
plumbing and fixing to true angles and surfaces
as necessary to ensure easy release during
stripping and for reconditioning as necessary
before re-use. The vertical strutting shall be
carried down to such construction as is
sufficiently strong to afford the required support
without damage and shall remain in position
until the newly constructed work is able to
support itself. Formwork to soffits of solid slabs,
etc. shall be deemed to be to slabs not
exceeding 250mm thick unless otherwise
described. Formwork to sides of items
described as "in ground" means formwork from
top of bearing level to top of surface bed.
Where a height above bearing level is stated,
the bearing level is taken to be the surface bed
or slab level as the case may be. Formwork to
sides of bases, pile caps, ground beams, etc.
will only be measured where it is prescribed by
the Engineer for design reasons. Formwork
necessitated by irregularity or collapse of
excavated faces will not be measured and the
cost thereof shall be deemed to be included in
the allowance for taking the risk of collapse of
the sides of the excavations, provision for which
is made in "Earthworks".

(vi) Temperature sensor.
Warranty:
The rectifier / charger and inverter subassemblies shall be guaranteed (parts and labour on
site) for one year following the start-up date.
15.2 TECHNICAL REQUIREMENT FOR NEW UPS SYSTEMS
i) OPERATING PRINCIPLES
a) The UPS unit shall operate in double-conversion mode (also called on-line mode), it shall be a
VFI-type UPS (as per standard IEC 62040-2), made up of the components described in detail in
this specification.
b) Normal operation (normal AC source available): The rectifier supplies the inverter with DC
current while the charger simultaneously floats charges the battery. The load is continuously
supplied with dependable electrical power by the inverter.
c) Operation on battery power (normal AC source not available or outside tolerances): Upon failure
or excessive deterioration of the normal AC source, the inverter shall continue to supply the load
from battery power without interruption or disturbance, within the limits imposed by the specified
battery backup time.
d) Battery recharges (normal AC source restored): When the normal AC source is restored, the
rectifier shall again power the inverter, without interruption or disturbance to the load, while the
charger automatically recharges the battery.
e) Transfer to bypass AC source:
i) In the event of an overload exceeding system capabilities (short-circuits, heavy inrush
currents, etc.) the load shall be automatically transferred, instantaneously and without
interruption, to the bypass AC source, on the condition that bypass power is available
and within tolerances.
ii) To ensure transfer in complete safety, the system shall simultaneously control the static
switches.
f) UPS maintenance:
i) For maintenance purposes, all electronic components shall be accessible from the front of
the UPS.
ii) In addition, a built-in manually operated mechanical bypass system shall be installed in UPS
unit.
iii) For personnel safety during servicing or testing, this system shall be designed to isolate the
UPS units while continuing to supply power to the load from the bypass AC source. Transfer
to the manual bypass mode and back shall be possible without interruption to the load.
iii) The UPS shall also include a device making it possible to isolate the rectifiers and the charges
from the normal AC source.
g) Battery maintenance:
For safe maintenance on the battery of each UPS unit, the system shall include a circuit breaker
to isolate the battery from the rectifier/charger and inverter. When the battery is isolated from
the system, the UPS shall continue to supply the load without interruption or disturbance, except
in the event of a normal AC source outage.

2.1
(i) Cold start (normal AC source absent):
The battery of each UPS shall be capable of ensuring UPS start-up even if normal AC power is
not available and continuing operation within the specified back-up time (start on battery power

of 0.9.
• The System shall be made up of 1 x 10kVA UPS units, with 30 minutes backup.

Documentation\Electrical\2518 - Elec Tech.Spec.doc
2.1
(ii) Variations: -±0.5 Hz
f) Synchronisation with bypass power:
(i) When bypass power is within tolerances:
To enable transfer to bypass power, the inverter output voltage shall be synchronised with
the bypass source voltage whenever possible. To that end, during normal operation, a
synchronisation system shall automatically limit the phase deviation between the voltages to
3 degrees, if the bypass source frequency is sufficiently stable (within adjustable tolerances
of ±0.5% to ±0.8% with respect to rated frequency).

bypass source is a generator set, the synchronisation tolerances shall be approximately ±8%
(adjustable) with respect to the rated frequency.
(iii) Autonomous operation following loss of synchronization with bypass power:
When the bypass source frequency deviates beyond these limits, the inverter shall switch
over to free-running mode with internal synchronisation, regulating its own frequency to
within ±0.1%. When bypass power returns to within tolerances, the inverter shall
automatically resynchronise.

270% for 150 milliseconds, to allow highly disturbed transient operating states (high
overloads, very high crest factors, etc.) without transferring the load to the bypass.

bypasses shall be controlled simultaneously by a built-in system. Instantaneous transfer of
the load form the inverters to bypass power and back shall take place without a break or
disturbance in the supply of power to the load, on the condition that the bypass source
voltage and frequency are within the specified tolerances and that the inverters are
synchronised.
• Transfer shall take place automatically in the event of a major overload or an internal inverter
fault.
• Manually initiated transfer shall also be possible.
• If the bypass power is outside the specified tolerances or is not synchronised with the
inverter, automatic transfer of the load from the inverter to bypass power shall take place
after a calibrated interruption adjustable from 13 to 1000 ms.
i) Static-switch protection:
• Each static switch shall be equipped with an RC filter for protection against switching
overvoltage’s and lightning strikes.
j) Discrimination and short-circuit capacity:
• If the bypass power is within the specified tolerances, the presences of the static switch shall
make it possible to use the short-circuit power of the bypass source to trip the downstream
protection devices of common inverter output.
• To ensure tripping in a selective manner, the available power shall be sufficient to trip
protection devices with high ratings (circuit breaker rated In/2 or UR fuses rated In/4, where
In is the rated UPS-system current).
