Receiving, Handling and Storage
Introduction
This manual covers the Receiving, Handling and Storage
instructions for Type 3AH vacuum circuit breakers shipped
separately from the switchgear. This section of the manual
is intended to help the user identify, inspect and protect
the circuit breaker prior to its installation.
Receiving Procedure
Make a physical inspection of the shipping container be-
fore removing or unpacking the circuit breaker. Check for
shipment damage or indications of rough handling by the
carrier. Check each item against the manifest to identify
any shortages.
Accessories such as the manual charging crank, the rack-
ing crank and the split plug jumper are shipped separately.
Shipping Damage Claims (when applicable) - Follow nor-
mal shipment damage procedures, which should include:
1. Check for visible damage upon arrival.
2. Visible damage must be noted on delivery receipt, and
acknowledged with driver's signature. Notation, "Pos-
sible internal damage, subject to inspection" must be
on delivery receipt.
3. Notify the Siemens Sales office immediately of any
shipment damage.
4. Arrange for carrier's inspection. Do not move the unit
from its unloading point.
Handling Procedure
1. Carefully remove the shipping carton from the circuit
breaker. Keep the shipping pallet for later use if the
breaker is to be stored prior to its installation.
2. Inspect for concealed damage. Notification to carrier
must take place within 15 days to assure prompt reso-
lution of claims.
3. Each circuit breaker should be appropriately lifted to
avoid crushing the side panels of the breaker, or dam-
aging the primary disconnect subassemblies.
Heavy weight. Can cause death, serious
injury, or property damage.
Use of a qualified rigger to hoist the circuit
breaker.
Type 3AH circuit breakers weigh (Table A-4).
4. The palleted circuit breaker can also be moved using a
properly rated fork-lift vehicle. The pallets are designed
for movement by a standard fork-lift vehicle.
Storage Procedure
1. When the breaker will be placed on its pallet for stor-
age, be sure the unit is securely bolted to the pallet
and covered with polyethylene film at least 10 mils
thick.
Indoor Storage - Whenever possible, store the circuit
breaker indoors. The storage environment must be clean,
dry and free of such items as construction dust, corrosive
atmosphere, mechanical abuse and rapid temperature
variations.
Outdoor Storage - Outdoor storage is not recommended.
When no other option is available, the circuit breaker must
be completely covered and protected from rain, snow, dirt
and all other contaminants.
Space Heating - Space heating must be used for both in-
door and outdoor storage to prevent condensation and
corrosion. When stored outdoors, 250 watts per breaker
of space heating is recommended.
