INTRODUCTION
GENERAL INTRODUCTION
NEW ATI enclosure integrates a new
4-pole changeover switch including
electronic’s control to meet standard
IEC 60947-6-1. Thanks to the chan-
geover switch technology, it is always
possible to manually operate the sys-
tem to guarantee the changeover panel
operation in any situation.
The new enclosure design allows
switch front panel access to:
• Avoid opening of the enclosure for
manual operation
• Allow electronic module access for
programming and monitoring
•Simplify connections between the
mechanical switch and the electronic
module.
With the mode switch in manual posi-
tion, Padlocking, as well as handle
insertion operations are then directly
accessible from the front panel.
The electronic module, also accessible
from the front panel, includes:
• Sources monitoring
• Metering display (V and f as standard)
• Test operations and Sequences pro-
gramming using keypad.
• ATI 1000 A
• ATI 1250 A
• ATI 1600 A
New ATI range models
MODEL
• ATI 250 A
• ATI 400 A
• ATI 630 A
• ATI 800 A
ATI TRANSFER PANEL RANGE
The new ATI panel range will be available from 250 A to 1600 A.
1. A mechanical switch.
2. A motorized block to operate the switch electrically.
3. An electronic module on the top of the motorized block, driving loss of mains
and main’s return sequence.
4. A reset button.
NEW MOTORIZED CHANGEOVER SWITCH
The new switch included in the enclosure is made of 3 different parts:
Standard offer includes Bottom cable entry. Top cable entry is offered as an
option.
Features and benefits:
• The new Motorisation block is inclu-
ded in a moulded case
• It is possible to remove the motorized
block and the electronic module
without being obliged to disconnect
the power cables
• Manual operation directly acts on the
shaft of the mechanical switch for
better reliability
• The complete enclosure meets stan-
dard IEC 60947-6-1 (ATS applications)
• The enclosure is self-powered (from
Main and Gen sources). There is no
need for an external power source to
allow automatic sequence after loss
of power
• All thresholds and timers can be set
using the display and the keypad, or
via modbus (optional)
•The standard product integrates
voltage and frequency control for
better diagnostic
• Main sensing circuit is 3 phases and
Gen sensing circuit is single phase
• Standard product includes, phase to
phase + phase to neutral voltage
measurement and displays system
frequency (phase 1) and switch num-
ber of operations.
• The product including metering allows
current measurement as well as power
metering (kW, kVar, kVA and PF).

tion information, padlocking and
Auto/Manual mode information are
optionally available. Option code is
TAUX.
INTRODUCTION (continued)
OPTIONS AVAILABILITY
Factory options are delivered pre-installed in the enclosures
Option 5:
• A switch allowing 277Vac specific
voltage option for customers requi-
ring voltage code V601 (480/277 Vac).
Option code is THVM.

features + current and power meter-
ing facilities on a larger backlit display.
This option also integrates option 6
(TAUX). Option code is TMET & TAUX.
Option 7:
•2IN/2OUT.1 plug in module allowing
auxiliary contacts for Main and
Generator available information is also
available as an option. Option code is
TIO2.
Option 8:
• 1 plug in communication module,
JBUS/MODBUS protocole, can
optionally be ordered allowing remote
communication of the changeover
system. Option code is TCOM.
Option 2:
•IP54 protection rating is available as
an option. A specific protection win-
dow must be installed on the front
panel of the enclosure to avoid water
infiltration in the enclosure. Option
code is TIP5.
Option 3:
•Solid neutral link is available as an
option on the switch itself, when
switching of the neutral cable is not
required. Option code is TLNK.
Option 4:
•Lightning protection is also available
as an option to avoid ATS damage in
case of a strike on the power cables.
This option is highly recommended
in stormy areas. Option code is TLPR
and TI02 is included.
Loose options are available, for customer mounting in the enclosures
