Precautions
JWIRING
•Use one of the following wires to connect to the
P7SA-10F/10F-ND/14F/14F-ND.
Stranded wire: 0.75 to 1.5 mm216 to 18 AWG
Solidwire: 1.0to1.5mm
216 to 18 AWG
•Tighten each screw of the P7SA-10F/10F-ND/14F/14F-ND to
atorqueof0.98NSm(10kgfScm) securely.
•Insure correct coil polarity, or the G7SA will not operate.
JCLEANING
The G7SA is not of enclosed construction. For this reason, do not
wash the G7SA with water or detergent.
JFORCIBLY GUIDED CONTACTS
(FROM EN50205)
If NO contacts become welded, all NC contacts will maintain a
minimum distance of 0.5 mm when the coil is not energized.
Similarly, if NC contacts become welded, all NO contacts will
maintain a minimum distance of 0.5 mm when the coil is
energized.
