SWITCHRACKS, PANEL BOARDS - General Information
Description:
“SWITCH-RACK” is a word usually adopted to indicate an ensemble of control units, signaling units, motor starters, switching units, and so on.
Switch-racks are mechanically assembled on robust frame with various fixing solutions (ground, wall, etc.), electrically wired up on purpose.
FEAM since over 40 years, designs and manufacturers switch-racks according to its own diagram or according to customer’s specifications, in full
compliance with European CENELEC standards.
SWITCHRACKS
INFORMATIONS:
Test and inspections:
All components and documents are tested and checked at the various working stages , according to FEAM’s “Quality Pans”.
The above mentioned Plans call for all test and checks necessary to ensure an execution “on purpose”. Whenever a strict, documented quality
control execution is required please advise FEAM Sales Department. When the switchrack is completed ,an effective working inspection is
carried out, and an “inspection report” is written. Customer’s inspectors are allowed in FEAM’s workshop to survey working evolution and
to witness final inspection.
Standard Tests and Checks:
• Visual and dimensional control
• Working control
• Equipment control
• Mechanical running control
• Hydrostatic test
• Insulation test
• Grinding check
• Insulation resistance measuring
• Insulation test / Electrical running test
Ordering:
The following technical information are needed to work out a switchrack. A direct consult with FEAM Sales Department is however
advisable, especially when problems of space arise.
A) Area classification and mode of protection.
B) Applicable standards
C) Power and auxiliary wiring diagrams or full, detailed description of switchrack’s work
D) Maximum overall dimensions.
Possibility of double front execution
E) Location of incoming and outgoing cable entries
F) Threading, size and number of hubs
G) Type of cable entries
H) Painting cycle, type and color
I) Switchrack’s location (indoor or outdoor)
L) Request of protective canopy(if needed)
N) “Vendor List” of components to be respected (if any)
Responsibility:
Once acknowledged the order, FEAM Technical Dept. issues electrical and mechanical manufacturing drawings.
These drawings are sent to customer “for approval” and whichever change has to be advised as soon as possible.
We take full responsibility for engineering, purchasing and assembling of components ,wiring and erection of the ensemble ready
for installation.
REMARK:
Due to the development of the national and international specifications and of the technology, the above technical characteristics showed
on this bulletin can be considered as binding on our confirmation only.

These enclosures are Classified as to explosion and fire hazards only in according to Standard UL1203 4° ed.
The explosion-proof enclosures are suitable for Class I, Group B Hazardous Locations only when provided with from M20 to M90, 1/2 in. to 3 in., supply
connection openings. If other supply connection openings are provided, then the enclosures are suitable for Class I, Groups C & D Hazardous Locations only.
The 1/2 in. NPSM operator openings are only suitable for enclosures marked for Class I, Groups B, C & D Hazardous Locations
The enclosures covered by this Certification may have electrical components installed inside. The installation of electrical components shall not reduce the
mechanical integrity of the enclosures.
The enclosures may or may not be provided with hinges for service of the enclosures only.
PROTECTION AGAINST CORROSION
All ferrous-metal other than stainless steel shall be protected against corrosion, except at joint surfaces and conduit threads There shall be no materials
applied to joint surfaces.
GROUNDING
Internal Ground Screw – Hexagon head screw M6 x 10 with a stainless steel flat and lock washer provided on the base of the enclosure body.
External Ground – Terminal colored green, marked with the letter or word “G”, “GROUND”, or marked with a grounding symbol.
SUPPLY CONNECTIONS
NPT and Metric Supply Connections - The side walls of the enclosure are provided with conduit openings or none may be supplied, in which case field drilling
and tapping instructions are provided with each enclosure. The entry is drilled and tapped completely through the enclosure wall, and the inside edge is
smoothed and well-rounded such that the conductor insulation will not be damaged when installed. All unused openings are closed with plated steel, plated
cast iron or aluminum close-up plugs which are threaded to match the opening. Closer-up Plugs have to be Listed for the same Class, Group and Division as
marked on Enclosure nameplate.
OPERATOR OPENINGS
The cover of the enclosure may be provided with operator openings in the cover only and located only as given in drilling and tapping instructions provided
with each Classified enclosure. All unused openings are closed with plated steel, plated cast iron or aluminum close-up plugs which are threaded to match the

ESX Flanges (gland plates) identification table
Standard availability in stock for enclosures without flanges
Please refer to below diagram to define quntity and position of side walls flanges
FC = flange on short side enclosure FL = Flange On Long Side Enclosure
Number 1 or 2 placed before sentence FC or FL define flange quantities. ATTENTION: on each enclosure side wall is allowed one single flange only
Example:
ESX-3322A-1FC-2FL= Enclosure Dim. 330x220x148mm with 1 flange only on 1 short side + 2 flanges one on each long side
ESX-5242A-2FC-2FL= enclosure Dim. 520x420x242mm with 2 flanges one on each short side + 2 flanges one on each long side
