MSS Installation Procedure
User Manual 10H52268UMA0 - Rev. 3 - 12/2020 5
1INSTALLATION PROCE URE
1.1 Introduction
2011/65/EU
Directive of the council for adapting the legal regulations of member states on the restriction of the use
of certain hazardous substances that can be used in the manufacture of electrical and electronic
equipment.
WARNING
DO NOT APPLY ELECTRICAL POWER TO THE MULTI-MODULE MSS SYSTEM BEFORE THE
CONSENT OF THE COMMISSIONING ENGINEER.
WARNING
THE SYSTEM EQUIPMENT SHOULD BE INSTALLED BY A QUALIFIED ENGINEER IN
ACCORDANCE WITH THE INFORMATION CONTAINED IN THIS CHAPTER. ALL EQUIPMENT NOT
REFERRED TO IN THIS MANUAL IS SHIPPED WITH DETAILS OF ITS OWN MECHANICAL AND
ELECTRICAL INSTALLATION.
WARNING - Battery hazards
EYE PROTECTION SHOULD BE WORN TO PREVENT INJURY FROM ACCIDENTAL ELECTRICAL
ARCS. REMOVE RINGS WATCHES AND ALL METAL OBJECTS. ONLY USE TOOLS WITH
INSULATED HANDLES. WEAR RUBBER GLOVES.
NOTE
REMOVE THE FUSES OF THE FANS BEFORE OPENING THE FAN COVERS. MAINTENANCE OF
FANS SHOULD BE CARRIED OUT WHEN THE MSS IS INSULATED FROM BOTH SUPPLY LINES.
This section describes the Multi-Module MSS System's environmental requirements and mechanical
considerations that must be considered when planning the positioning and cabling of the Multi-Module
MSS System.
Because every site has its peculiarities it is not the aim of this chapter to provide step-by-step
installation instructions but to act as a guide as to the general procedures and practices that should be
observed by the installing engineer.

Installation Procedure MSS
6 User Manual 10H52268UMA0 - Rev. 3 - 12/2020
1.2 Environmental Considerations
1.2.1 Multi-Module MSS System Location
The Multi-Module MSS System should be in a cool dry clean-air and well-ventilated environment with
adequate ventilation to keep the ambient temperature within the specified operating range.
The MSS must be mounted on concrete or another incombustible surface. The mounting floor must be
flat and even. The ambient environmental parameters must be within the specified range as shown in
the "Technical data" chapter on page 60.
All the equipment is cooled with the aid of internal fans. Cooling air enters the devices through the
ventilation grids located mainly in front of the cabinet or from the kickplates. Warm air will flow out from
the grids on the roof. To permit air to enter and exit and to prevent overheating or malfunctioning do
not cover the ventilation openings.
If necessary a system of extractor fans should be installed to aid cooling-air flow and a suitable air filter
should be used if the MSS is operating in a contaminated environment. Exhaust fans should be installed
where necessary to accelerate the ambient air circulation. In a dusty environment air filters should be
installed.
1.2.2 Storing
If the unit is to be stored before installation it is recommended that it be stored in a dry environment
with temperatures in the range of -10°C to 70°C. Use original packing materials or other suitable means
to keep the unit clean.

1.3 Mechanical Considerations
1.3.1 System Composition
The centralized parallel system for the cabinet composition is shown in Table 1. All the cabinets are the
same height and are installed side-by-side for aesthetic effect.

1.3.2 CHASSIS version: installation and footprint
To allow correct air flow for the cooling system leave a minimum distance of 500mm between
the top of the cabinet and the ceiling of the installation area.

1.3.4 Moving the Cabinets
From delivery point the route to the unit's final position must be planned such that all openings are
wide enough for the unit and that floors can support its weight (for instance check that doorways lifts
ramps etc. are adequate).
WARNING
ENSURE ANY LIFTING EQUIPMENT USED IN MOVING THE MSS CABINET HAS SUFFICIENT
LIFTING CAPACITY.
EXERCISE EXTREME CARE WHEN HANDLING MSS CABINETS TO AVOID EQUIPMENT DAMAGE
OR INJURY TO PERSONNEL.
Ensure that the MSS weight is within the designated surface weight loading (kg/cm2) of any handling
equipment. MSS and optional cabinets (battery cabinets top cable entry cabinets etc.) can be handled
by means of a forklift or similar equipment. For operations with a forklift it is necessary to remove either
the lower protection panel located at the base of the cabinet and rear panels (or both side panels).
If the equipment cannot be moved by forklift rollers should be used.
Because the weight distribution in the cabinet is uneven use extreme care during handling and
transporting.
When moving the unit by forklift lift the unit from the rear to protect the front panel. Do not exceed a 15
degrees tilt with the forklift. The bottom structure will support the unit only if the forks are completely
beneath the unit.
Handling with straps is not authorized.
