INTRODU TION
Before u ing thi product, be ure to read thi chapter carefully.
Thi chapter de cribe afety precaution when u ing the relay. Before in talling and u ing the
equipment, read and under tand thi chapter thoroughly.
It’ not a ecret – electricity can be dangerou and when thing go wrong live can be at
take!
Electrical engineer are Indu trial afety doctor , o it’ our duty to keep employee health
and maintain a quality of life that we all de erve by providing afe work practice to avoid
electrical accident .
How much electricity is dangerous?????
URRENT EFFE T
0.5 – 3mA Tingling en ation
3 – 10mA Mu cle contraction (painful)
10 – 40mA “can’t let go” phenomena
40 – 75mA Re piratory paraly i (po ibly
fatal)
75 – 200mA Ventricular fibrillation (likely
fatal)
200 – 500mA Heart clamp tight
>1.5A Ti ue and organ began to burn
Fact: A 10-amp circuit breaker was designed to protect equipment – not people!
The relay i developed with zero percentage of ri k factor by it own de ign. The current
carrying path and circuit are i olated from the metal ca e and tructure. Suitable clearance
depending on the type of in ulation required for different cla e are provided.
The relay confirm to Product afety requirement tandard IEC 60255-27.

HEALTH AND SAFETY
It deal with the handling of relay in proper way. An individual to be con idered a ‘qualified’
with regard to certain equipment in the workplace, but ‘unqualified’ a to other equipment.
“An employee, who i undergoing on the job training and who, in the cour e of uch training,
ha demon trated the ability to perform dutie afely at hi or her level of training and who i
under the direct upervi ion of a qualified per on al o con idered to be a qualified per on for
the performance of tho e dutie .”
The following requirement mu t be met, in the order given, before circuit or equipment are
re-energized, even temporarily.
 People handling the equipment hould be aware about the relay afety handlet.
 En ure that the product i in the off condition before working on the conducting or terminal
ide.
 A qualified per on mu t conduct te t and vi ual in pection , a nece ary, to verify that tool
electrical jumper , hort , ground and other uch device have been removed, o that the
circuit and equipment can be afely re-energized.
 Employee expo ed to the hazard a ociated with re-energizing the circuit or equipment mu t
be warned to tay clear of the circuit and equipment.
 Each lock and tag mu t be removed by the employee who applied it or omeone el e under
that employee’ direct upervi ion.
 A vi ual determination that all employee are clear of the circuit and equipment mu t be
made.

WARNING
urrent transformer circuit
Never allow the current tran former (CT) econdary circuit connected to thi
equipment to be opened while the primary y tem i live. Opening the CT
circuit will produce a dangerou high voltage.
Exposed terminals
Do not touch the terminal of thi equipment while the power i on, a the
high voltage generated i dangerou .
Residual voltage
Hazardou voltage can be pre ent in the DC circuit ju t after witching off the
DC power upply. It take about 30 econd for the voltage to di charge.
AUTION
Earth
Earth the earthing terminal of the equipment ecurely.
Operation conditions
U e the equipment within the range of ambient temperature, humidity and
du t a detailed in the pecification and in an environment free of abnormal
vibration.
Ratings
Before applying AC voltage and current or DC power upply to the equipment,
check that they conform to the equipment rating .
Printed circuit board
Do not attach and remove the printed circuit board while the DC power to the
equipment i on, a thi may cau e the equipment to malfunction.
External circuit
When connecting the output contact of the equipment to an external circuit,
carefully check the upply voltage u ed and prevent the connected circuit from
overheating.
onnection cable
Carefully handle the connection cable without applying exce ive force.

Modification
Do not modify thi equipment, a thi may cau e the equipment to
malfunction, and any uch ca e , warranty may be affected.
DE OMMISIONING AND DISPOSAL
De-commissioning
The upply input (auxiliary) for the equipment may include capacitor acro
the upply or to earth. To avoid electric hock or energy hazard , after
completely i olating the upplie to the equipment, the capacitor hould be
afely di charged via the external terminal prior to de-commi ioning.
ANGER
Disposal
When di po ing of thi equipment, do o in a afe manner according to local
regulation . It i recommended that incineration and di po al to water cour e
i avoided. En ure the relay i in de energized condition and take precaution
to avoid hort circuit .

HANDLING OF RELAY
Protective rela s generall of robust construction require careful treatment prior to installation
on site. Care must be taken when unpacking and installing the rela s so that none of the parts
are damaged. Rela s must be handled b skilled personnel. The following should be taken into
account while handling the rela :
The rela use components that are sensitive to electrostatic discharges. The rela
comprises of various semi-conductor devices which can damage if touched b means of
direct contact. Handle the cards in static free environment since electrostatic discharge
can affect performance of the rela or cause damage to the cards.
The electronic circuits are well protected b the metal case and the internal module should
not be withdrawn unnecessaril .
The rela is normall shipped in separatel packed condition. After unpacking, see if there
is an mechanical damage to the cabinet, the nameplate, terminal blocks etc. Damage of
an such sort identified shall be intimated to works.
Avoid plugging in/ pulling out the cards when the power is ON.
Do not appl CT inputs when auxiliar suppl is switched OFF.
If the cards are withdrawn for testing, ensure proper positioning while replacing.
Keep the rela s in well-packed condition in a dust-free dr environment without direct
exposure to sunlight.
The rela is shipped from factor after detailed testing b our Qualit Control Department.
However, according to the customer requirement the rela settings/ functions can be verified
before commissioning at respective sites with proper testing kits.
STORAGE
If rela s are not to be installed immediatel upon receipt the should be stored in a place free
from dust and moisture in their original boxes. At most care should be taken while storage.
Storage temperature: -25ºC to +70ºC.
