About this Manual
This manual provides the information you need to install, operate, and maintain the TMD IV.
Read this manual before working with the system. For personal and system safety, and for the best product
performance, make sure you thoroughly understand the manual before installing, operating, or maintaining
this machine.
Important Safety Information
Please note the following important safety information about installing, operating, handling, transporting,
maintaining, and disposing of the TMD IV. The following symbols are used on the TMD IV itself and in this
manual, and convey the following important safety information.
CAUTION. Risk of electric shock.
All warnings and cautionary text in this manual is marked with this symbol. Please read all cautions
and warnings very carefully and fully obey them.
The Difference between a Caution and Warning Message
Two types of safety message are used in this manual, and the distinction between the two is as follows.
CAUTION. Failure to observe may cause minor injury or damage to the equipment.
WARNING. Failure to observe could result in death or serious injury.
General Safety Precautions
Here are the safety precautions you should follow when installing, operating, or maintaining the TMD IV.
CAUTION: The protection provided by the safety elements of this system may be impaired if the
equipment is used in a manner other than specified in this manual.
WARNING. User must follow all applicable safety procedures related to this product. High voltages
and high temperatures are present within the system enclosure during normal operation.
WARNING. Do not attempt to defeat safety interlocks provided with this product. There are no
user-serviceable parts inside the system enclosure. This product must be serviced only by authorized
Thermo Fisher Scientific service personnel.
WARNING. Failure to follow safe installation and servicing procedures could result in death or
serious injury.
•Make sure only qualified personnel perform installation and maintenance procedures in
accordance with the instructions in this manual.

Ramsey Oretronic IV Tramp Metal Detector REC 4479C Page 10
•Allow only qualified electricians to open and work in the electronics cabinet, power-supply
cabinet, control cabinet, or switch boxes.
•Covers over the electronics and rotating parts must always remain in place during normal
operation. Remove only for maintenance, with the machine’s power OFF. Replace all covers
before resuming operation.
•During maintenance, a safety tag (not supplied by the factory) must be displayed in the ON/OFF
switch areas instructing others not to operate the unit (ANSI:B157.1).
WARNING. High voltage that may be present on leads could cause electrical shock.
•All switches must be OFF when checking input AC electrical connections, removing or inserting
printed circuit boards, or attaching voltmeters to the system.
•Use extreme caution when testing in, on, or around the electronics cabinet, PC boards, or
modules. There are voltages in excess of 115–230 V in these areas—even with the main door
open.
WARNING. Use only the procedures and new parts specifically referenced in this manual to ensure
specification performance and certification compliance. Unauthorized procedures or parts can
render the instrument dangerous to life, limb, or property.
WARNING. The TMD IV should not be operated at more than the production rate stated on your
equipment specification sheet, or used in applications other than those stated in the original order.
WARNING. Do not place or store objects of any kind on the TMD IV.
WARNING. Tampering with and/or removing any safety guards and other safety devices fitted to
the TMD IV is strictly forbidden. If the existing guards or safety devices are modified, you must verify
that any changes made comply with the appropriate safety regulations before the TMD IV is used.
Conventions Used in This Manual
Here is a summary of the conventions used in this manual.
•The term “TMD IV” is a general term that refers to Thermo Scientific Ramsey Oretronic IV Tramp Metal
Detector.
