Wiring location 

Never use the product in an explosive 
atmosphere where flammable gases or 
explosives are handled.  Doing so may 
result in a fatal accident, such as fire or 
explosion. 

Foreign matter in hydraulic fluid may result 
in malfunction of the product.  Keep 
hydraulic fluid clean (NAS 1638 class 10 or 
better).  

When handling the valve, pay attention not 
to apply tension to the cable.  Doing so 
may cause malfunction due to cable 
breakage. 

The connector is not included with the valve.   
Wire the valve correctly by using the 
specified standard connector and referring 
to the instructions for the connector.  For 
the use of YUKEN’s connector TK290457-1, 
see the ”Wiring” section of this manual.

 

Never touch the connector while the power 
is on.    Doing so may cause electric shock, 
resulting in a fatal accident. 

Do not modify the product.    Doing so may 
prevent the product from achieving the 
design performance and impair safe 
operation.

Do not step on or put any heavy object on 
the product.  Doing so may result in 
damage to the product/equipment or injury 
from collapse/falling. 

Valve characteristics may vary depending 
on the load pressure and fluid temperature.   
Make adjustments so that the valve can 
accelerate, decelerate, and stop safely 
across the entire range of operating 
pressures and fluid temperatures. 

Make sure of correct wiring! 

Do not apply load to the cable.
