When soldering the relay to the PC board, solder temperature must not
exceed +270°C, and solder time must not exceed 5 seconds. If
necessary to hold the relay in place during soldering, the terminals of
the coil and movable contact arm may be slightly bent after insertion
through the board holes.

CAUTION: Do not bend the terminals of the stationary contact
arms, as this may alter contact adjustment.

The polyester cover of the relay is bonded to the relay base, but is not
hermetically sealed. Therefore, if the board on which the relay is
soldered is to be cleaned by immersion, cleaning time must not exceed
two minutes. If fluorocarbons, chlorinated or hydrocarbon cleaning
solutions are used, the temperature of the solution must not exceed
+77°C. If aqueousorganic solutions are used, temperature must not
exceed +80°C.

After board cleaning, the tape on the top of the relay must be
punctured before the relay is put into service. If the tape is not

punctured, any normal outgassing could result in excessive contact
resistance at load currents of less than the contact rating.
