This section presents relevant aspects of safety, installation and maintenance of the TM1/TM2.

Technical Manual –TM1/TM2 | MA-010| 2016-03-21 | Ver.: 6.30 7

Temperature Monitor

Safety Symbols

This manual uses three types of risk classification, as shown below:

Caution

The Caution symbol is used to alert the user of a potentially hazardous operating or maintenance

procedure that demands greater caution in its conduction. There may be minor or moderate injuries, as

well as damages to the equipment.

Warning

The Warning symbol is used to alert the user of a potentially hazardous operating or maintenance

procedure in which extreme caution must be taken. There may be serious injuries or death. Possible

damages to the equipment are irreparable.

Electric Shock Hazard

The Electric Shock Hazard symbol is used to alert the user of an operating or maintenance procedure

that may result in electric shock if not strictly observed. There may be minor, moderate, serious injuries

or death.

General Symbols

This manual uses the following general symbols:

Important

The Important symbol is used to highlight relevant information.

Tip:

The Tip symbol represents instructions that facilitate use and access of functions in the TM1/TM2.

Minimum profile recommended for the TM1/TM2 operator and maintainer

Installation, maintenance and operation of equipment in electric power substations require

special cares and, therefore, all recommendations of this manual, applicable standards, safety

procedures, safe work practices and good judgment must be used during all handling stages of

the Temperature Monitor (TM1 and TM2).

For use of this manual, an authorized and trained person has knowledge of the inherent risks –

both electrical and environmental –involved in handling the TM1 and TM2.

Only authorized and trained personnel –operators and maintainers –should handle this equipment.

Technical Manual –TM1/TM2 | MA-010| 2016-03-21 | Ver.: 6.30 8

Temperature Monitor

a) The operator or maintainer must be trained and authorized to operate,

ground, turn on and turn off the TM1/TM2, following maintenance procedures

according to the safety practices established, under the sole responsibility of the

TM1/TM2 operator and maintainer;

b) Be trained in the use of IPEs, CPEs and first-aid;

c) Trained in the working principles of the TM1 and TM2, as well as its

configuration.

d) Follow regulatory recommendations regarding interventions in any type of

equipment included in an Electric Power System.

Instructions for test and installation

This manual must be available to those responsible for installation, maintenance and users

of the Temperature Monitor –TM1/TM2.

To guarantee user safety, equipment protection and correct operation, the following minimum

cares must be followed during the TM1/TM2 installation and maintenance:

1. Read this manual carefully before installation, operation and maintenance of

the TM1/TM2. Errors in installation, maintenance or adjustments of the TM1/TM2

Technical Manual –TM1/TM2 | MA-010| 2016-03-21 | Ver.: 6.30 9

Temperature Monitor

can cause undue operations of the tap changer in load, unsatisfactory voltage

regulation, undue alarms or pertinent alarms may also fail to be emitted.

2. The installation, adjustments and operation of the TM1/TM2 must be done by

personnel trained and acquainted with the electric motors, power transformers,

tap changers on load or voltage regulators, control devices and control circuits of

substation equipment.

3. Special attention must be paid to installation of the TM1/TM2, including the

type and size of the cables and terminal strips used, as well as the procedures

for commissioning, including correct parameterization of the equipment.

The TM1/TM2 must be installed in a sheltered environment (a panel without doors in a control room or

in a closed panel, in cases of outdoor installation) where the temperature and humidity specified for the

equipment are not exceeded.

Do not install the TM1/TM2 near sources of heat like heat resistors, incandescent lamps and devices

with high power or with heat dissipaters. Its installation near ventilation orifices or where it can be

affected by forced air flow, like outlet or inlet of cooling fans or forced ventilation ducts, is not

recommended.

On conducting dielectric strength tests on the wiring (applied voltage), the ground cables connected to

terminal 17 of the TM1/TM2 must be disconnected in order to prevent destruction of the protections

against overvoltage existing inside the device due to application of high voltages for a long period (e.g.:

2 kV for 1 minute).

Cleaning and decontamination instructions

Take care when cleaning the TM1/TM2. Use ONLY a cloth wet with soap or detergent diluted

in water to clean the cabinet, front plate or any other part of the equipment. Do not use

abrasive materials, polishers or aggressive chemical solvents (like alcohol or acetone) on any of

its surfaces.

Turn off and unplug the equipment before cleaning any of its parts.

Inspection and Maintenance instructions

The following observations must be followed for inspection and maintenance of the TM1/TM2:

If the panel where the TM1 / TM2 was installed has a window , use a G20 film - or higher - to avoid

direct incidence of sunlight ( UV ) at the equipment . Even if the glass of this window is dark, such

procedure is necessary.

Technical Manual –TM1/TM2 | MA-010| 2016-03-21 | Ver.: 6.30 10

Temperature Monitor

Do not open the equipment. In it, there are no parts reparable by the user. This should be done by the

Treetech technical assistance, or by technicians accredited by it.

This equipment is completely maintenance-free, being that visual and operational inspections,

periodical or not, may be conducted by the user. These inspections are not mandatory.

Opening of the TM1/TM2 at any time will imply in loss of the product warranty. In cases of undue

opening of the equipment, Treetech will also not be able to warrant its correct functioning, regardless of

the warranty period having expired or not.

All parts of this equipment must be supplied by Treetech, or by one of its accredited suppliers,

according to its specifications. If the user wishes to purchase it otherwise, he must strictly follow

Treetech’s recommendations for this. This way, the performance and safety for the user and the

equipment will not be compromised. If these specifications are not followed, the user and the

equipment may be exposed to unforeseen and unnecessary risks.
