17 INSTALLATION REQUIREMENTS
17.1 Maintenance Bypass
ABB recommends that a maintenance bypass (not supplied with the PCS100 UPS-I) is fitted. The maintenance bypass
allows maintenance to be performed on the PCS100 UPS-I without disruption to the load.
ABB requires the input and output breakers of a maintenance bypass to be lockable for an ABB service personnel to
carry out any work on the PCS100 UPS-I. Please note that ABB LV breakers do not provide this as standard but as an
option.
Note:
A Fail-Safe Bypass (if fitted) is not a substitute for a maintenance bypass because it does not offer isolation of the
PCS100 UPS-I.
17.2 Floor Requirements
All enclosures must be installed on a horizontal fireproof surface.
Do not exceed ± 0.2° change in slope between adjacent enclosures.
Do not exceed ± 5 mm in elevation between adjacent enclosures.
Note:
Additional precaution should be taken for PCS100 UPS-I system weight, especially in battery PCS100 UPS-I systems
where one energy storage enclosure weights 2043 kg.
17.3 Electromagnetic Compatibility (EMC)
The PCS100 UPS-I is designed for commercial and industrial applications. It is not suitable for connection to a low-
voltage utility that is supplying residences unless additional measures are taken as per IEC 62040-2.
17.4 Location
The PCS100 UPS-I is designed for location in a restricted access location only.
The PCS100 UPS-I is designed for connection by fixed wiring.
The PCS100 UPS-I system location should be clean electrical room with controlled environment temperature and
humidity according the requirements under Technical Data section.
Because of different limits of ambient temperatures of PCS100 UPS-I system and energy storage (40 ºC and 25 ºC)
for cost saving on HVAC systems it is advisable to install them to different electrical rooms.
17.5 Phase Rotation
The PCS100 UPS-I does not support negative phase rotation.
17.6 Power Systems
The PCS100 UPS-I is designed for use in TN power systems. For any other type of power distribution system contact
ABB for more information.
17.7 Harmonics
The PCS100 is designed to tolerate disturbances such as voltage and current harmonics in the load or supply.
Excessive distortion can lead to the stressing of components leading to reduction in the lifetime of some
components. For harmonics >8%THDv contact ABB for more information.
