Specific Product Precautions 4
Be sure to read this before handling the products. Refer to the back cover for safety instructions.
For 3/4/5-port solenoid valve precautions, refer to the "Handling Precautions for SMC Products"
and the "Operation Manual" on the SMC website: https://www.smcworld.com
Light Indication
Caution
When equipped with light/surge voltage suppressor, the light win-
dow turns red when solenoid a is energized, and it turns green
when solenoid b is energized.

Changing the Connector Entry Direction
Caution
To change the connector's entry direction, set the switch on the
top of the connector block to the FREE position, before turning
the connector. Make sure to set the switch back to the LOCK po-
sition before connecting the connector. (When the switch is diffi-
cult to slide, move the connector a little so that it will slide easier.)
If an excessive force is applied on the connector in the LOCK po-
sition, the connector block may be damaged. Also, using in such
a way that the connector floats in the FREE position, it may cause
the lead wire, etc., to break. Thus, refrain from using in these
ways.

Manifold Mounting
When attaching a manifold to a mounting surface, etc., with bolts,
if the entire bottom surface of the DIN rail contacts the mounting
surface in a horizontal mounting, it can be used by simply secur-
ing both ends of the DIN rail. However, for any other mounting
method or for side facing and rear facing, etc., secure the DIN rail
with bolts at uniform intervals using the following as a guide: 2 to
5 stations at 2 locations, 6 to 10 stations at 3 locations, 11 to 15
stations at 4 locations, 16 to 20 stations at 5 locations, 21 to 25
stations at 6 locations, 26 to 30 stations at 7 locations, and more
than 30 stations at 8 locations.
In addition, even in the case of a horizontal mounting, if the mount-
ing surface is subject to vibration, etc., take the same measures
indicated above. If secured at fewer than the specified number of
locations, warping or twisting may occur in the DIN rail and mani-
fold, causing trouble such as air leakage.
