Safety Precautions
Refer to the Common Relay Precautions for precautions that apply to all Relays.
• Use two M3 screws to attach case-surface-mounted models
(LY1F, LY2F, LY3F, and LY4F) and tighten the screws securely.
(Normal tightening torque: 0.98 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 100 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 10 A or More When Using an LY Relay
with the Following Sockets
When you use an LY-series relay in combination with the PTF08A,
PTF08A-E, or PT08, connect each of the following terminal pairs: (1)
to (2), (3) to (4), and (5) 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.
Attaching and Removing Relay Hold-down Clips
When you attach a Hold-down Clip to or remove it from a Socket, wear gloves
or take other measures to prevent injuring your fingers on the Hold-down Clip.
