Receiving, handling and storage
Receiving and handling
Upon receipt, carefully inspect the trans-
fer switch for damage that may have oc-
curred during transit. If damage is evi-
dent, or there is visible indication of
rough handling, immediately file a dam-
age claim with the transportation com-
pany, and notify your local ABB sales
office.
Do not remove the shipping packaging
until ready to install the switch.
Storage
If the unit will not be placed into service
immediately, store the transfer switch in
its original package in a clean, dry loca-
tion. To prevent condensation, maintain a
uniform temperature. Store the unit in a
heated building, allowing adequate air cir-
culation and protection from dirt and
moisture. Storing the unit outdoors could
cause harmful condensation inside the
transfer switch enclosure.
HAZARD OF EQUIPMENT
OVERTURNING
When moving with a fork lift, do not re-
move the shipping packaging until the de-
vice is in its final location.
Failure to follow this instruction may
result in personal injury or equipment
damage.
Warning
Indicates a hazardous situation that,
if not avoided, could result in death or
serious injury.

Read these safety instructions
carefully before using this product!
HAZARD OF ELECTRIC SHOCK,
EXPLOSION, OR ARC FLASH
• Apply appropriate personal protective
equipment and follow safe electrical
work practices.
• This equipment must only be installed
and serviced by qualified electrical per-
sonnel.
• Before performing visual inspections,
tests, or maintenance on the equip-
ment, disconnect all sources of electric
power. Assume that all circuits are live
unless they are completely de-ener-
gized, tested, grounded, and tagged.
Pay particular attention to the design of
the power system. Consider all sources
of power, including the possibility of
backfeeding.
• Disconnect all sources of electric power
before removing or making source side
or load side connections to the transfer
switch.
• Always use a properly rated voltage
sensing device at all line and load con-
nections to confirm transfer switch is
disconnected from all live electrical
sources.
• Turn off power supplying transfer
switch before doing any other work on
or inside switch.
Failure to follow these instructions could
result in death or serious injury.
Danger
Indicates a hazardous situation that,
if not avoided, will result in death or
serious injury.

Zenith ZTG series automatic transfer switches, from 30 A
up to 1200 A, are designed for use in general purpose
commercial and industrial low voltage automatic transfer
switch applications. Zenith ZTG series automatic transfer
switches can be operated electrically by LCD control
interface (HMI) or manually by using the handle. You can
select the operating mode by the slide switch (Hand -
Locking - AUTO) on switch front. Configuration is done
by LCD HMI.
