1.1. IMPORTANT
• This document provides important instructions for the safe use, movement and connection of the MASTERYS BC uninterrupt-
ible 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 either partially or wholly, and in any way, is strictly 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 provided 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 only be moved by two people at least.
They MUST take position at the sides of the UPS with respect to the direction of movement.
• The unit must remain in a vertical position at all times.
• Connect the PE ground conductor fi rst before making any other connection.
• 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 2.4.1).
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).
• 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).
• 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.
• Before connecting any external battery cabinets, ensure they are fully compatible with the UPS model used.
• 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 the protection panels in order to carry out work on parts
under dangerous voltage.
• Risk of explosion if batteries are replaced with others of the wrong type.
• Used batteries must be disposed of at authorised waste disposal centres.
It is very dangerous to touch any part of the batteries as there is no insulation between the batteries and the mains
power source.
