Safety

Preliminary Advice

Preliminary advice and general safety precautions relating to installing smart relays:

zRemember that only qualified personnel are authorized to implement the smart relay.

zRead this instruction sheet and the User Guide to learn the procedures prior to installing, wiring, operating, maintaining of controlling the smart relay.

zThe end user should keep this User Guide and the product instructions sheet.

zInstall the smart relay by following the instructions in the instruction bulletin and the User Guide. Improper installation may result in failure or malfunction of the smart relay.

zMake the necessary ground and short circuit the connections.

zCheck the operating conditions, as described in the User Guide. If you are unsure of the technical characteristics, contact Schneider Electric.

zFluctuations or variations in the power supply voltage should not exceed the tolerance thresholds stated in the technical characteristics, as they may lead to operating failures and potentially dangerous situations.

zTake any steps necessary to ensure that an application interrupted by a power failure continues to operate correctly after restoring power and make sure also that no dangerous situation whatsoever arises.

zTake any steps necessary to prevent involuntary activation of the relay.

zAutomation and control devices must be installed in areas where they are protected against any risk of involuntary activation.

zEnsure that all connections to the control system meet applicable safety standards.

zEnsure that you comply with all applicable standards for emergency stop systems in order to avoid potentially dangerous situations. Ensure that releasing the emergency stop system does not cause the automated system to suddenly restart.

zInstall the smart relay only in environments described in the User Guide. Do not use the smart relay in environments subject to excessive temperatures, elevated relative humidity, condensation, corrosive gases, or excessive shocks.

zThe smart relay should be used in "Pollution level 2" environments. This level defines the effect of pollution on the insulation.

zDefinition of level 2 Pollution: Only non-conductive pollution arises, except for occasional temporary conductivity caused by condensation. Do not use smart relays in environments lower than those specified in IEC Standard 60664-1.

zUse appropriate wires according to current and voltage requirements. Tighten the screws of the terminal according to the specified torque.

zUse an IEC 60127 approved fuse, in conformity with the requirements for current and voltage, to protect the power line and output circuits. This is not required when a device including a smart relay is intended for Europe.

zUse an EU-approved switch. This is not required when a device including a smart relay is intended for Europe.
