INTRODUCTION
Before sing this prod ct, be s re to read this chapter caref lly.
This chapter describes safety preca tions when sing the relay. Before installing and sing the eq ipment,
read and nderstand this chapter thoro ghly.
It’s not a secret – electricity can be dangero s and when things go wrong lives can be at stake!
Electrical engineers are Ind strial safety doctors, so it’s o r d ty to keep employees health and maintain a
q ality of life that we all deserve by providing safe work practices to avoid electrical accidents.
How much elect icity is dange ous?????
CURRENT EFFECT
0.5 – 3mA Tingling sensations
3 – 10mA M scle contractions (painf l)
10 – 40mA “can’t let go” phenomena
40 – 75mA Respiratory paralysis (possibly fatal)
75 – 200mA Ventric lar fibrillation (likely fatal)
200 – 500mA Heart clamps tight
>1.5A Tiss e and organs began to b rn
Fact: A 15 amp circuit breaker was designed to protect equipment – not people!
The relay is developed with zero percentage of risk factor by its own design. The c rrent carrying paths and
circ its are isolated from the metal case and str ct re. S itable clearance depending on the type of ins lation
req ired for different classes are provided.
The relay confirms to Prod ct safety req irement standard IEC 60255-27.

HEALTH AND SAFETY
It deals with the handling of relay in proper way. An individ al to be considered as ‘q alified’ with regard to
certain eq ipment in the workplace, b t ‘ nq alified’ as to other eq ipment. “An employee, who is
ndergoing on the job training and who, in the co rse of s ch training, has demonstrated the ability to
perform d ties safely at his or her level of training and who is nder the direct s pervision of a q alified
person also considered to be a q alified person for the performance of those d ties.”
The following req irements m st be met, in the order given, before circ its or eq ipments are re-energized,
even temporarily.
People handling the eq ipment sho ld be aware abo t the relay safety handlet.
Ens re that the prod ct is in the off condition before working on the cond cting or terminal side.
A q alified person m st cond ct tests and vis al inspections, as necessary, to verify that tools electrical
j mpers, shorts, gro nds and other s ch devices have been removed, so that the circ its and
eq ipments can be safely re-energized.
Employees exposed to the hazards associated with re-energizing the circ it or eq ipment m st be
warned to stay clear of the circ its and eq ipment.
Each lock and tag m st be removed by the employee who applied it or someone else nder that
employee’s direct s pervision.
A vis al determination that all employees are clear of the circ its and eq ipments m st be made.
For any q eries related to relays, feel free to contact ALIND.
Wa ning: Befo e wo king at the ea of unit, isolate all voltage and cu ent supplies.
Caution:
Befo e ca ying out any wo k on equipment you should be familia with the
contents of the Safety Section o the Safety Guide AR** elays and the atings on
the equipment’s ating label.

WARNING
Cu ent t ansfo me ci cuit
Never allow the c rrent transformer (CT) secondary circ it connected to this eq ipment
to be opened while the primary system is live. Opening the CT circ it will prod ce a
dangero s high voltage.
Exposed te minals
Do not to ch the terminals of this eq ipment while the power is on, as the high voltage
generated is dangero s.
Residual voltage
Hazardo s voltage can be present in the DC circ it j st after switching off the DC power
s pply. It takes abo t 30 seconds for the voltage to discharge.
CAUTION
Ea th
Earth the earthing terminal of the eq ipment sec rely.
Ope ation conditions
Use the eq ipment within the range of ambient temperat re, h midity and d st as
detailed in the specification and in an environment free of abnormal vibration.
Ratings
Before applying AC voltage and c rrent or DC power s pply to the eq ipment, check
that they conform to the eq ipment ratings.
P inted ci cuit boa d
Do not attach and remove the printed circ it board while the DC power to the eq ipment
is on, as this may ca se the eq ipment to malf nction.
Exte nal ci cuit
When connecting the o tp t contacts of the eq ipment to an external circ it, caref lly
check the s pply voltage sed and prevent the connected circ it from overheating.
Connection cable
Caref lly handle the connection cable witho t applying excessive force.

RELAYS DIVISION
Modification
Do not modify this eq ipment, as this may ca se the eq ipment to malf nction, and
any s ch cases, warranty may be affected.
DECOMMISIONING AND DISPOSAL
De-commissioning
The s pply inp t (a xiliary) for the eq ipment may incl de capacitors across the s pply
or to earth. To avoid electric shock or energy hazards, after completely isolating the
s pplies to the eq ipment, the capacitors sho ld be safely discharged via the external
terminals prior to de-commissioning.
Disposal
When disposing of this eq ipment, do so in a safe manner according to local reg lations.
It is recommended that incineration and disposal to water co rses is avoided. Ens re the
relay is in de energized condition and take preca tions to avoid short circ its.
TECHNICAL SPECIFICATIONS FOR SAFETY
1. P otective class
IEC 60255-27:2005 Class I (This eq ipment req ires a protective
cond ctor (earth) connection to ens re
ser safety.
2. Envi onment
IEC 60255-27:2005 Poll tion degree 2 (Normally only non-cond ctive poll tion
occ rs except occasionally a temporary
cond ctivity ca sed by condensation is to
be expected.)
3. Ove voltage Catego y
IEC 60255-27:2005 Category III (The a xiliary energizing circ its of the
eq ipment are connected to a common
battery, common mode transient voltages
of a relatively high val e may appear on
the s pply leads, and differential mode
voltages may arise from switching in other
circ its connected to the same battery
4. Contact data Test voltage across open contact: 1 kV DC for
1 min so rce.

HANDLING OF RELAY
Protective re ays genera y of robust construction require carefu treatment prior to insta ation on site.
Care must be taken when unpacking and insta ing the re ays so that none of the parts are damaged.
Re ays must be hand ed by ski ed personne . The fo owing shou d be taken into account whi e hand ing
the re ay:
The re ay use components that are sensitive to e ectrostatic discharges. The re ay comprises of
various semi-conductor devices which can damage if touched by means of direct contact. Hand e
the cards in static free environment since e ectrostatic discharge can affect performance of the
re ay or cause damage to the cards.
The e ectronic circuits are we protected by the meta case and the interna modu e shou d not be
withdrawn unnecessari y.
The re ay is norma y shipped in separate y packed condition. After unpacking, see if there is any
mechanica damage to the cabinet, the namep ate, termina b ocks etc. Damage of any such sort
identified sha be intimated to works.
Avoid p ugging in/ pu ing out the cards when the power is ON.
Do not app y PT inputs when auxi iary supp y is witched OFF.
If the cards are withdrawn for testing, ensure proper positioning whi e rep acing.
Keep the re ays in we -packed condition in a dust-free dry environment without direct exposure to
sun ight.
The re ay is shipped from factory after detai ed testing by our Qua ity Contro Department. However,
according to the customer requirement the re ay functions can be verified before commissioning at
respective sites with proper testing kits.
STORAGE
If re ays are not to be insta ed immediate y upon receipt they shou d be stored in a p ace free from dust
and moisture in their origina boxes; at most care shou d be taken whi e storage.
Storage temperature: -25ºC to +55ºC.
