Precautions
Caution
Do not touch the terminal area of the Relays or the socket terminal
area (charged area) while power is ON. Electric shock will result.
Relays with Forcibly Guided Contacts
A Relay with Forcibly Guided Contacts is a Relay with which a safety
category circuit can be configured.
Wiring
Use one of the following wires to connect to the P7SA-10F/10F-ND/
14F/14F-ND.
Stranded wire:0.75 to 1.5 mm
2
Solid wire:1.0 to 1.5 mm
2
Tighten each screw of the P7SA-10F/10F-ND/14F/14F-ND to a
torque of 0.98 N·m securely.
Wire the terminals correctly with no mistakes in coil polarity, other-
wise the G7SA will not operate.
Cleaning
The G7SA is not of enclosed construction. Therefore, do not wash
the G7SA with water or detergent.
Forcibly Guided Contacts (from EN50205)
If an NO contact becomes welded, all NC contacts will maintain a
minimum distance of 0.5 mm when the coil is not energized. Like-
wise if an NC contact becomes welded, all NO contacts will maintain
a minimum distance of 0.5 mm when the coil is energized.
Correct Use
Relays with Forcibly Guided Contacts
While the Relay with Forcibly Guided Contacts has the previously
described forcibly guided contact structure, it is basically the same
as an ordinary relay in other respects. Rather than serving to prevent
malfunctions, the forcibly guided contact structure enables another
circuit to detect the condition following a contact weld or other mal-
function. Accordingly, when a contact weld occurs in a Relay with
Forcibly Guided Contacts, depending on the circuit configuration, the
power may not be interrupted, leaving the Relay in a potentially dan-
gerous condition (as shown in Fig. 1.)
To configure the power control circuit to interrupt the power when a
contact weld or other malfunction occurs, and to prevent restarting
until the problem has been eliminated, add another Relay with Forc-
ibly Guided Contacts or similar Relay in combination to provide
redundancy and a self-monitoring function to the circuit (as shown in
Fig. 2).
The G9S/G9SA Safety Relay Unit, which combines Relays such as
the Relay with Forcibly Guided Contacts in order to provide the
above-described functions, is available for this purpose. By connect-
ing a contactor with appropriate input and output to the Safety Relay
Unit, the circuit can be equipped with redundancy and a self-monitor-
ing function.
