Section 2.0 - SAFETY PRECAUTIONS
2.1. Only qualified persons familiar with the construction and
operation of switchboards should perform work described
in this set of instructions. Such work should be performed
only after reading this complete set of instructions.
in this set of instructions. Such work should be performed
only after reading this complete set of instructions.
2.2. Follow safety related work practices, as described in NFPA
70E, part II, at all times.
2.3. Hazardous voltages in electrical equipment can cause
severe personal injury or death. Energizing a switchboard
for the first time after initial installation or maintenance is
potentially dangerous. Inspection and maintenance should
be performed on switchboards and equipment to which
power has been cut off, disconnected, and electrically iso-
lated so that no accidental contact can be made with
energized parts.

2.4. Some types of electrical equipment will cause harmonics
in the electrical system which may result in overheating.
Consider this condition when determining switchboard
loading, as possible de-rating of equipment may be
necessary.

Section 3.0 - SWITCHBOARD PREPARATION
3.1 Receiving
Prior to shipment, each switchboard is inspected to ensure
structural and electrical construction is in compliance with
applicable specifications, codes, and standards. Depending
on the size and number of sections, the switchboard is
divided into shipping sections of one or more vertical sec-
tions and placed onto wooden skids. Each shipping section
is packaged, securely blocked and braced for shipment.
Whatever method of shipment, every precaution is taken
to minimize the possibility of damage and to ensure its safe
arrival. Relatively delicate instruments or devices may be included
and the assembly must be handled carefully when unloading.

When the equipment arrives at the destination, the packing
list or marking tag(s) should be checked against the equip-
ment actually received to make sure the shipment is correct
and complete. Claims for shortages or incorrect material must
be made in writing within 30 days after receipt of the shipment

ance and a waiver of all such claims.
ance and a waiver of all such claims.
On shipments with more than one shipping group, marking tags
are attached to each crate or package for identification. In lieu of
the marking tags, the rating label on each section contains the
section marking. Refer to the general arrangement drawing for
the location of each unit within the group lineup.

3.2 Inspection
Inspect the equipment as soon as possible after receiving for
any damage that may have occurred in transit. Carefully remove
packing to inspect for any possible damage. Retain the packing
material for equipment storage or return shipment if neces-
sary. The switchboard should remain in an upright position
and secured to the shipping skid to prevent distortion of the
bottom frame when moving or handling.

3.3 Shipping Damage Claims
All claims for lost or damaged goods in transit are to be handled
by purchaser directly with the carrier. Notification to carrier within
the 15 day limit on concealed damage is essential if loss resulting
from unsettled claims is to be eliminated or minimized.

3.3.1. When shipment arrives, note whether equipment
is properly protected from the elements. Note trailer
number on which the equipment arrived. Note block-
ing of equipment. During unloading make sure count
agrees with delivery receipt.

3.3.2. Make immediate inspection upon arrival for visible
damage. This should be done prior to unloading when
possible. When total inspection cannot be made on
vehicles prior to unloading, close inspection during
unloading must be maintained and visible damage
noted. Take pictures if possible.

3.3.3. Any visible damage must be noted on the delivery
receipt and acknowledged with the driver’s signature.
The damage should be detailed as much as possible.
It is essential that a notation “Possible internal damage,
subject to inspection” be included on delivery receipt.

3.3.5. Notify the Siemens Sales Office immediately of any
damage.
3.3.6. Arrange for a carrier inspection of damage immediately.
IMPORTANT: Do not remove equipment from the place
it was set when unloading. Be sure this location is properly
protected to ensure further damage will not occur. Equip-
ment must be inspected by carrier prior to handling after
receipt. This eliminates loss due to claims by carrier that
equipment was damaged or further damaged on site
after unloading.

3.3.7. Be sure equipment is properly protected from any further
damage by covering it properly after unloading. Equip-
ment should be stored in a clean dry place having a
uniform temperature to prevent condensation and
protected from further damage.
