Receiving, Handling and Storage
Receiving and Handling
Upon receipt, carefully inspect the By-
pass/Isolation Automatic Transfer Switch
for damage that may have occurred
during transit. If damage is evident, or
there is visible indication of rough han-
dling, immediately file a damage claim
with the transportation company, and no-
tify your local ABB sales office.
Do not remove the shipping package until
ready to install the Bypass/Isolation Auto-
matic Transfer Switch.
Storage
If the unit will not be placed into service
immediately, store the Bypass/Isolation
Automatic Transfer Switch on its original
package in a clean, dry location. To pre-
vent condensation, maintain a uniform
temperature. Store the unit in a tempera-
ture controlled building, allowing ade-
quate air circulation and protection from
dirt and moisture. Storing the unit out-
doors could cause harmful condensation
inside the Bypass/Isolation Automatic
Transfer Switch enclosure.
HAZARD OF EQUIPMENT
OVERTURNING
When moving with a fork lift, do not re-
move the shipping package until the de-
vice is in its final location.
Warning
Hazard of equipment overturning. Failure to
follow this instruction will result in personal
injury or equipment damage.
Avertissement
Risque de renversement de l'équipement. Le
non-respect de cette instruction entraînera
des blessures corporelles ou des dommages
équipement.

HAZARD OF ELECTRIC SHOCK,
EXPLOSION, OR ARC FLASH
• Wear appropriate personal protective
equipment and follow safe electrical
work practices.
• This equipment must only be installed
and serviced by qualified electrical per-
sonnel.
• Disconnect all sources of electrical sup-
ply before performing visual inspec-
tions, tests, service or maintenance on
the equipment. Assume that all circuits
are live unless they are completely
de-energized, tested, grounded, and
tagged. Pay particular attention to the

Bypass/Isolation Automatic Transfer
Switches, consisting of two TruONE Auto-
matic Transfer Switches from 100 A up to
600 A, are used to provide a continuous
source of power for critical loads. The
transfer from one source to another is
performed automatically if the voltage of
Source 1 falls below preset limits.
TruONE Automatic Transfer Switch is de-
signed for use on emergency or standby
systems and is rated for total system or
motor loads.

2. Product Overview
Bypass/Isolation Automatic Transfer Switches, Zenith ZBTS
T-series, from 100 A up to 600 A, are used to provide a
continuous source of power for critical loads by
automatically transferring from Source 1 power to Source 2
power if the voltage of Source 1 falls below preset limits.
The bypass/isolation features allow the primary Automatic
Transfer Switch to be inspected, tested and maintained
without interrupting power to the load. They also provide
redundant power transfer if the ATS is disabled or removed
from service.

Notice
A protective device such as a molded case cir-
cuit breaker or fused disconnect switch MUST
be installed on both sources of incoming
power for circuit protection and as a discon-
nection device.
Remarquer
Un dispositif de protection tel qu'un dis-
joncteur à boîtier moulé ou un sectionneur à
fusible DOIT être installé sur les deux sources
d'alimentation entrante pour la protection du
circuit et comme dispositif de déconnexion.
Bypass/Isolation Automatic Transfer
Switch consists of these main modules:
• Two Automatic Transfer Switches:
- ATS is always draw-out version
(lower switch module)
- Bypass can be fixed or draw-out
version (upper switch module)
• Customer main connections, Load,
Source 1 and Source 2, on the left side
of the cabinet
• Control Panel (bottom module)
- Customer connections: Generator
start/stop terminals
- Control circuit
- Place for optional accessories
• Racking in/out -mechanism
• Both switches have separate operation
panel HMI at the door
The modules containing the switch are
connected to the busbars located at the
rear of the modules and the entire pack-
age is mounted in an enclosure. ATS
switch in the lower switch module is al-
ways a draw-out version that includes an
in/out rack for easy maintenance. The up-
per switch module, Bypass switch, is
available in either a fixed or draw-out ver-
sion, but all the functions are exactly the
same for both Bypass and ATS switches.
The left side of enclosure is for cable lugs
of Load, Source 1 and Source 2. The lugs
are located behind transparent covers.
See the location of lugs in Fig. 2.6.
Control Panel is located in the bottom
module equipped with own inside door.
The front side of the door is reserved for
the customer connections e.g. generator
start/stop terminals and also includes an
empty space for the accessories. On the
back side of the Control Panel door are all
other components which are necessary
for the control system.
The switch racking in/out mechanism is
on enclosure’s door, also in the upper
switch module, when the Bypass switch is
a draw-out version. The tool for the rack-
ing in/out system is located in the mecha-
nism behind the transparent cover. The
default location of the tool is the lower
switch module, where ATS is always the
draw-out version.
Danger
Hazardous voltage. Turn OFF all power before
installation, adjustment, or removal of the
transfer switch or any of its components.
Danger
Tension dangereuse. Coupez toute alimenta-
tion avant l'installation, le réglage ou le retrait
du commutateur de transfert ou de l'un de ses
composants.
Warning
Due to hazardous voltage and current, ABB
recommends that ABB certified technician or
qualified electrician perform the installation
and maintenance.
Avertissement
En raison de la tension et du courant dange-
reux, ABB recommande qu'un technicien certi-
fié ABB ou un électricien qualifié effectue
l'installation et la maintenance.

version.

2.2.3 Interlocks
Automatic Transfer Switches are electri-
cally interlocked to prevent switches from
being operated to different sources at
the same time.
The system provides the ability to with-
draw the ATS (or the Bypass switch, if it is
the draw-out version) for test and / or
maintenance purposes without interrupt-
ing the load. During operation, the con-
tacts of the Bypass switch are closed par-
alleling the ATS contacts, which then
allows withdrawal of the ATS to the
“TEST” or “ISOLATED” locations. The sys-
tems include mechanical and electrical in-
terlocks that prevent cross-service.
2.2.4 Internal door locking
The doors are mechanically interlocked
with draw-out switch versions so that the
doors do not open when the switch is en-
ergized or in CONNECTED/TEST loca-
tions. If the Bypass switch is fixed, then
there is no mechanical interlock on the
upper door.
