installation.
Do not install these valves in explosive atmospheres.
If these valves are exposed to water or oil droplets, ensure that they
are protected.
If it is intended to energise a valve for an extended period please con-
sult SMC.
If air leakage causes associated equipment to malfunction cease using Double

Check fixings while pressure and power are applied. Initial function
and leakage tests should be performed after installation.
Only install once safety instructions have been read and understood.

1. Loosen the top screw and remove the connector housing from the
terminal spades on the solenoid.
2. Remove the housing screw and insert a screwdriver into the slot
on the underside of the DIN cap and carefully remove the block.
3. Loosen the terminal screws on the block and insert the stripped
leads. Secure each lead by re-tightening the appropriate terminal
screw.
4. Tighten the housing grommet nut to secure the cable.
