Preliminary Advice and General Safety Precautions on Installing Smart Relays
• • Remember that only qualified personnel are authorized to implement the smart relay. Read the instruction sheet and the User Manual to check procedures before starting installation, wiring, operation, maintenance orinspection of the smart relay. This User Manual and the product instruction sheet should be kept by the end user. Install the smart relay module following the instructions in the instruction bulletin and in the User Manual. Incorrect installation can result in failure or malfunction of the smart relay. Power down the device before starting installation, removal, wiring, maintenance or inspectionof the smart relay system. Check to ensure no voltage is present. Make the necessary ground and short circuit connections. Ensure that operating conditions are as described in the User Manual. If you are uncertain about specifications, contact Schneider Electric. Fluctuations or variations in the supply voltage should not exceed the tolerance thresholds stated in the technical specifications, asthey may cause operating failures and lead to potentially dangerous situations. Take all necessary measures to ensure that an application interrupted by a break in the supply voltage can continue correctly and also ensure that no dangerous states, no matter how brief, may occur. Take all necessary measures to avoid unwanted relay triggering. Automation and control devices must be installed so thatthey are protected against any risk of involuntary actuation. It is essential to ensure that all control system connections meet applicable safety standards.

Take care to meet the standards that apply to emergency stop systems in order to avoid potentially dangerous situations. Ensure that releasing the emergency stop system does not causethe automated system to suddenly restart. Install the smart relay module only in environments described in the User Manual. Do not use the smart relay in locations where it is subjected to high temperature, high humidity, condensation, corrosive gases or excessive shocks. The environment for use of the smart relay module is “Pollution degree 2.” This refers to a degree of pollution in themicroenvironment that determines the effect of pollution on the insulation. Pollution degree 2 defines “Only non-conductive pollution occurs except that occasionally a temporary conductivity caused by condensation is to be expected.” Do not use the smart relay modules in environments inferior to those specified in IEC 60664-1. Use wires of the correct size according to voltage and current requirements.Tighten terminal screws to the specified tightening torque. Use an IEC 60127 approved fuse, conforming to voltage and current requirements, on the smart relay module power line and on the smart relay output circuits. This is a requirement when equipment incorporating the smart relay is destined for Europe. Use an EU-approved circuit breaker. This is a requirement when equipment incorporating thesmart relay is destined for Europe.

DANGER
HAZARD OF ELECTRIC SHOCK, BURN OR EXPLOSION Turn off all power before starting installation, removal, wiring, maintenance or inspection of the smart relay system. Failure to follow this instruction will result in death, serious injury or equipment damage.
WARNING
EXPLOSION HAZARD • According to CSA C22.2No 213: This equipment is suitable for use in Class 1, Division 2, Groups A, B, C, D or non-hazardous locations only. Substitution of components may impair suitability for this specified environment. • Confirm that the power supply voltage and its tolerances are compatible with those of the smart relay. • Do not disconnect equipment unless power has been switched off or the area is known to be…
