2.3.2 Relay Connection and Diagram
Before installation of the relay check the correct working procedure as to ensure safety. The
Terminal exposed during installation may present a hazardous voltage unless the equipment
is electrically isolated. Any disassembly of the equipment may expose parts to hazardous
voltage. Electronic parts may be damaged if suitable electrostatic discharge (ESD)
precautions are not taken. Voltage and current connection should be made using insulated
crimp termination to ensure that terminal block insulation requirements are maintained for
safety. To ensure that wires are correctly terminated the correct crimp terminal and tool for
wire size should be used. The equipment must be connected in accordance with the
appropriate connection diagram.
Before Energizing the relay following should be checked
• Voltage rating and polarity.
• CT circuit rating and integrity of connection.
• Protective fuse rating.
• Integrity of the earthing connection.
• Current rating of external wiring, applicable as per application.
2.3.3 Relay Operating Condition
The equipment should be operated within the specified electrical and environmental limits.
