1.1. IMPORTANT
• This document provides important instructions for the safe use, movement and connection of the MASTERYS BC uninterruptible
power system (UPS).
• SOCOMEC retains the full and exclusive ownership rights over this document. Only a personal right to use the document for the
application indicated by SOCOMEC is granted to the recipient of the document. The reproduction, modifi cation, distribution of
this document partially or wholly and in any way is prohibited except upon Socomec’s express prior written consent.
• This document is not a specifi cation. SOCOMEC reserves the right to make any changes to information without prior notice.
• The unit must only be installed and activated by qualifi ed technical personnel who have been authorised by SOCOMEC.
The UPS MUST be handled carefully by at least two people.
• The unit must remain in a vertical position at all times.
• Connect the PE ground conductor fi rst before making any other connection.
UPS mains power supplies (rectifier and bypass) must be protected from voltage transients with devices that are
suited to the installation; the mains voltage transients must be limited to 2.5 kV. These devices must be sized to
consider 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 expose the UPS to rain or liquids in general. Do not insert foreign bodies.
The installer is responsible for implementing the backfeed protection with the use of AC input line isolation devices
external to the UPS (see section 2.6.1).
Before working on this circuit
- Isolate the Uninterruptible Power System (UPS)
- Then check for Hazardous Voltage between all terminals
including the protective earth
Risk of Voltage Backfeed
• For the purpose of warning electrical technicians against backfeed situations not caused by the UPS, which may arise when a
particular load fault is present while the UPS is operating in stored energy mode, or while unbalanced loads are supplied through
a particular power distribution system e.g. an impedance grounded IT system, the installer must attach the labels provided to
all primary power isolators installed remotely from the UPS area and on external access points, if present, between the said
isolators
and the UPS.
In particular the label must be attached to the external AC input line isolation service (backfeed insulation).
• The UPS may be powered from an IT distribution system with a neutral conductor.
• Keep this manual in a convenient place for future consultation.
• If the unit fails it must only be repaired by authorised technicians who have been specially trained for this purpose.
• This equipment complies with European Community directives for industrial equipment and bears the approval mark
• The UPS requires three-phase plus neutral input connections (3P+N).
• The UPS can be powered by an IT distribution system with a neutral conductor.
The connecting bars are made of aluminium!
Use only aluminium cables or cables with tin-plated eyelets for the connections.
• Do not connect the output neutral to ground. The UPS does not modify the neutral setup of the system; the use of an isolation
transformer is required should it be necessary to modify the neutral setup downstream of the UPS.
• At the end of the UPS system’s lifetime it should only be entrusted to specialist disposal companies, which are required to
dismantle and dispose of its constituent components in accordance with existing national legislation.
• Before connecting the external battery cabinet check it is fully compatible with the UPS model.
• The use of external battery cabinets not supplied by the manufacturer is not recommended.
• Switch off and isolate the UPS and wait for 5 minutes before removing protection panels to carry out work on parts under
dangerous voltage.
• There is a risk of explosion if batteries are replaced with others of the wrong type.
• Batteries are considered toxic waste. If replaced, the used batteries must only be entrusted to specialist disposal companies.
Batteries must not be disposed of with other industrial or domestic waste, as stipulated by local legislation.
