The PTF@A can be mounted on a track or with screws.. The measurements in parentheses are for the LY@-CR (built-in CR circuit). Safety Precautions Refer to the Common Relay Precautions for precautions that apply to all Relays. Precautions for Correct Use Use two M screws to attach case-surface-mounted models (LYF, LYF, LYF, and LY4F) and tighten the screws securely. (Normal tightening torque:.9 N m) For Relays with Tab Terminals, select a wire diameter for the lead wires that connect to the faston receptacle terminals that is within the allowed range for the load current. Do not impose excessive external force on the Relay when inserting the Relay to the faston receptacle or pulling the Relay out from the faston receptacle. Do not attempt to insert a terminal diagonally or insert or pull out more than one terminal at the same time. LY Single-contact Relays are for power switching applications. Do not use the LY Series for switching minute loads of ma or less, such as signals. About the Built-in Diode and CR Elements The diode or CR element that are built into the Relay are designed to absorb the reverse voltage from the Relay coil. If a large surge in voltage is applied to the diode or CR element from an external source, the element will be destroyed. If there is the possibility of large voltage surges that could be applied to the elements from an external source, take any necessary surge absorption measures. Applying A or More When Using an LY Relay with the Following Sockets When you use an LY-series relay in combination with the PTFA, PTFA-E, or PT, connect each of the following terminal pairs: () to (), () to (4), and () to (6). Relay Replacement To replace the Relay, turn OFF the power supply to the load and Relay coil sides to prevent unintended operation and possible electrical shock.
