Certified Standards
Forcibly Guided Contacts (from EN50205)
G7S-@-E
• EN standards, VDE certified
EN61810-1 (Electromechanical non-specified time all-or-nothing
relays)
EN60255-23 (Contact performance)
EN50205 (Relays with forcibly guided (linked) contacts)

If an NO contact becomes welded, all NC contacts will maintain a
minimum distance of 0.5 mm when the coil is not energized. Likewise
if an NC contact becomes welded, all NO contacts will maintain a
minimum distance of 0.5 mm when the coil is energized.
Safety Precautions
Be sure to read the precautions for “Precautions for All Relays” and “Precautions for All Relays with Forcibly Guided
Contacts” in the website at:http://www.ia.omron.com/.
Indication and Meaning for Safe Use
CAUTION
Precautions
for Safe Use
Indicates a potentially hazardous situation
which, if not avoided, may result in minor
or moderate injury or in property damage.
Supplementary comments on what to do
or avoid doing, to use the product safely.
!CAUTION
Do not pass currents of 6 A or more when using this
product in combination with the P7S-14F/14P/14A
Socket. Doing so may result in fire. Use this product in
combination with the P7S-14F-END/14P-E.
Precautions for Correct Use
Wiring
• Use one of the following wires to connect to the P7S-14F-END.
Stranded wire: 0.75 to 1.5 mm2
Solid wire:
1.0 to 1.5 mm2
• Tighten each screw of the P7S-14F-END to a torque of 0.78
to 0.98 N·m.
• Wire the terminals correctly with no mistakes in coil polarity,
otherwise the G7S will not operate.
• If you use the P7S-14F-END, the release time of the G7S will be
longer because the P7S-14F-END has a built-in diode to absorb
coil surge. Confirm operation under actual conditions before you
use the P7S-14F-END.
Cleaning
The G7S is not of enclosed construction. Therefore, do not wash the
G7S with water or detergent.
Mounting
The G7SA can be installed in any direction.
