1. Introduction
This document contains all necessary information for the installation, operation and maintenance of ABB
Sace MNS R low-voltage switchboards. Like all the switchboards produced by ABB Sace, also these
boards are designed for several system configurations. For this reason, our products can be subjected
to technical-constructive variations (Custom-made) according to the system requirements.
Therefore, it is necessary to refer to the most updated ABB Sace technical documentation, especially
in case of any possible variation.
Anyway, it is advisable that all the installation, start and service operations are carried out by qualified
personnel.
1.1 Consequences in case of non-compliance
ABB declines any responsibility in the following cases:
• Negligent handling of low-voltage switchboards and non-conformity with safety and operation rules.
• Insufficient maintenance, non-compliance with the procedures here described or inadequate repairs
carried out by unqualified personnel or with inadequate equipments.
• Any damage suffered during transportation.
• Inappropriate use.
• Modifications to low-voltage switchboards, which have not been carried out by authorized and qualified
personnel.
