Siemens 3AH Installation Operation & Maintenance

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 before
removing or unpacking the circuit breaker. Check for ship-
ment damage or indications of rough handling by the carrier.
Check each item against the manifest to identify any short-
ages.
Accessories such as the manual charging crank, the racking
crank and the split plug jumper are shipped separately.
Shipping Damage Claims (when applicable) - Follow normal
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 ship-
ment 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 cir-
cuit 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 resolution of
claims.
3. Each circuit breaker should be appropriately lifted to
avoid crushing the side panels of the circuit breaker, or
damaging the primary disconnect subassemblies.
Heavy weight. Can cause death, serious
injury, or property damage.
Use of a qualified rigger to hoist the circuit
breaker.
Circuit breaker weights (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 circuit breaker will be placed on its pallet for
storage, 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 atmo-
sphere, 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 indoor
and outdoor storage to prevent condensation and corrosion.
When stored outdoors, 250 watts per circuit breaker of space
heating is recommended.
