NON-TECHNICAL PRE-COMMISSIONING
2.2
On delivery of the transmitter, the following
non-technical procedures should be observed and
completed.
NOTE
Non-technical procedures are defined as being
those procedures that do not require technical
knowledge of transmitter circuits or their
operation to complete.
2.2.1 ACCEPTANCE OF SHIPMENT:
All
shipments should be inspected for transit damage
prior to acceptance.
Sufficient manpower or mechanical assistance
should be on hand when removing the transmitter
cabinet from its packing crate. The crate may
weigh in excess of 400 kilograms (867 pounds)
2.2.2 UNPACKING INSTRUCTIONS:
The
unpacking instructions are dictated by the method of
packaging for shipment. Transmitters not shipped by
electronic equipment moving specialists may be
packed in wooden crates, with the number of crates
determined by the extent of disassembly for
shipment. Instructions accompany any crate
requiring special unpacking information. Packing
lists provide detailed listings of shipment contents.
Do not accidentally discard the transmitter
access keys during unpacking procedures. The
keys required to open the front and rear doors,
including the keys for the optional IEC215
mechanical safety interlock system when
installed, are located in a bag attached to the
transmitter's plastic wrapping material.
NOTE
The transmitter will be partially disassembled for
shipment. As a minimum, the power transformer
will be removed. The extent of any additional
disassembly will be dictated by the shipping
method, site information provided by the user and
the handling equipment of the mover.
(a) It is recommended the crates be positioned
near the transmitter's final assembly location
prior to unpacking. The following crated and
uncrated weights of the major assemblies is
provided to ensure personnel are aware of
lifting requirements.

base of the crate and carefully lift away the
crate panels.
(e) Lift/slide the transmitter cabinet off the base of
its crate.
2.2.3 CABINET PRE-POSITIONING
(see
figure MD-28 for dimensional information): Prior to
installing the AC power transformer and when
removed for shipment, the fan trays and RF power
modules, place the transmitter cabinet in its assigned
position.
NOTE
It is assumed the final orientation and positioning
of the transmitter has been pre-determined, based
on the dimensional information provided with the
pre-installation package.
(a) Ensure the cabinet's location will accommodate
entry of AC power wiring from the AC input
interlock switch.
(b) Ensure the cabinet's location will accommodate
connection of the RF feed cable to the RF
output connection.
