Receiving, handling and storage
Receiving and handling
Upon receipt, carefully inspect the switch
for damage that may have occurred during
transit. If damage is evident, or there is
visible indication of rough handling,
immediately file a damage claim with the
transportation company, and notify your
local ABB sales office.
Do not remove the shipping package until
ready to install the switch.
Storage
If the unit will not be placed into service
immediately, store the switch on its
original package in a clean, dry location. To
prevent condensation, maintain a uniform
temperature. Store the unit in a heated
building, allowing adequate air circulation
and protection from dirt and moisture.
Storing the unit outdoors could cause
harmful condensation inside the switch
enclosure.
HAZARD OF EQUIPMENT
OVERTURNING
When moving with a forklift, do not
remove the shipping package until the
device is in its final location.
Failure to follow this instruction will result
in personal injury or equipment damage.

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
personnel.
• Before performing visual inspections,
tests, or maintenance on the equipment,
disconnect all sources of electric power.
Assume that all circuits are live unless
they are completely deenergized, tested,
grounded, and tagged. Pay particular
attention to the design of the power
system. Consider all sources of power,
including the possibility of backfeeding.
• Turn off switch before removing or
making load side connections.
• Always use a properly rated voltage
sensing device at all line and load to
confirm switch is off.
• Turn off power supplying switch before
doing any other work on or inside switch.
Failure to follow these instructions could
result in death or serious injury.
