Safety Precautions
1. Safety Arrangements
1:1. General
All persons performing installation or service
on rotating machines and electrical equipment
should be authorised and familiar with general
safety rules and IEC symbols as well as local
requirements, rules and regulations. In case of
doubt the local management should be con-
sulted.
SPM will not be responsible for any accident
caused by persons not observing this Safety
Precautions
.
When performing installation or service on
machines in potentially explosive atmosphere,
the requirements according to ATEX EN 60079
should be followed.
1:2. Disconnection
Before starting installation work on machines,
make sure that main power is off and will stay
off until the work is done. Do not simply pull the
switch - remove the fuses, lock the fuse box, put
up warning signs. Check all terminals to ensure
that the equipment is voltage free by using a
voltage tester.
1:3. Electrical Installation
Always read the instructions delivered with the
equipment before performing installation or ser-
vice on electric equipment. If you are in doubt,
please contact your local SPM representative
before installing the equipment. Damage of the
equipment caused by incorrect installation is not
covered by product warranty. Before starting
installation work, make sure that the main power
switch is in off position and will stay off until the
work is done. Check that all terminals, marked
with protective earth IEC symbol, are properly
connected to the protective earthing conduc-
tor of the building installation wiring. In some
countries, the term "protective grounding" is
used instead of "protective earthing". Earth and
ground are used synonymous in this installation
instruction. Choose installation tools that are
safe and suitable for its working environment.
Electrical risks can sometimes be eliminated by
using air, hydraulic or handpowered tools. These
are especially useful in harsh conditions.
1:4. System Components
To ensure optimum safety for user and environ-
ment, only original system components available
from SPM should be used. When using non-
original components, the compliance with EU
directive with respect to electric safety, EMC
and machine safety is not guaranteed by SPM.
1:5. Reapplying Power
For human safety, ensure the electrical equip-
ment or installation is electrically safe. Before
starting the machine, make sure that all protec-
tion covers on the machine are mounted and
secured.
2. Installation Precautions
2:1 Installation of Measuring Units and
Measuring Terminals
Measuring units and terminals should be located
in a protected position assigned by the local
management. The units shall be easily accessible
for undisturbed measurements and service. Sig-
nal cables should not be located close to power
supply cables. The measuring equipment should
be intended and specified for use in existing
environment.
It is important that you read the operating
instructions completely and follow all safety
precautions before operating the measuring
units. Electrical connections and wiring should
be performed only by suitably trained personnel.
2:2 Work Regulations
All personnel should be provided with the local
work regulation before any work is commenced.
It is important that parts of metal, rubber and
plastics are dumped in special containers. Such
parts can cause bad accidents and production
disturbances if dropped on the wrong place.
From an environmental point of view, wrapping
materials should be collected so as not to cause
damage.
Precautions should also be taken when drill-
ing, tapering and grinding to avoid chips and
grindings causing accidents and production
disturbances.
2:3 Inspection and Acceptance
Inspection of transducer positioning, connec-
tions, cable laying, TMU installations and strap-
ping should take place after finished installation.
The cables should be marked in accordance with
agreement with the local contact. Inspection
protocol in accordance with the local regulations
should be used.
