3. Mounting and Connection 

  Do not touch or go near the product while the power is ON. Failure to observe this 

could lead to electric shocks or burns. 

 

 

  Make sure that foreign matter does not enter the product during mounting or wiring. 

There is a risk of load damage or fires resulting from contact faults or operation faults.

  Do not use a product that is damaged during transportation, mounting or wiring. 

Failure to observe this could lead to fires or malfunctions. 

  If the mounting screw size is changed or an insufficient number is used, or if the 

mounting onto the mounting rail (IEC35mm width) is incomplete, the product may fall off.

  If the control circuit wiring is long, turning OFF the control voltage may not open the 

circuit because of a stray capacitance. 

  Never manually operate the product in a live state. Failure to observe this could lead 

to electric shocks or burns. 

  If the product is stored in a box, always close the cover while the power is ON. 

Failure to observe this could lead to electric shocks. 

  Do not mount the product on the floor or ceiling. Mounting on the floor or ceiling will 

affect the contact’s conductive performance, operation performance, durability, etc. 

3.1  Mounting 

 Mount the product in a dry place that has little dust, corrosive gas or vibration. 

 The correct mounting position is a vertical surface. However, the product can be mounted vertically up to 

30

 in each direction.   

 Tighten the mounting screw with the mounting torque shown in the Table below.

Horizontal mounting 

(Excluding reversing type) 

If horizontal mounting is unavoidable, turn the product 90

 in 

the counterclockwise direction from the correct vertical 
mounting state, and mount. 
The characteristics will not change much from when the 
product is mounted horizontally but mechanical endurance may 
drop somewhat. 
This mounting method is not available with the reversing type. 
Also, the product cannot be mounted horizontally onto a 
mounting rail (IEC35mm width). 

 Mounting on IEC35mm rail 

The T10 to T32 series and SR-T series can be mounted 
on an IEC35mm wide rail. The rail height is 7.5 or 15mm. 
The rail dimensions are shown on the right.   
When mounting the rail onto a panel, keep the rail 
mounting screw pitch within the values shown on the 
right to maintain the mechanical strength. 
Always maintain the dimensions shown on page 8 as 
these influence temperature rises and product life. 

 

IEC35mm wide rail dimension 

 

Height 7.5mm wide rail: P = 250 or less 
Height 15mm wide rail: P = 500 or less 
For each, the dimensions show the case when the device is mounted on a 
7.5mm high mounting rail with the clearances shown in Table 1 on page 8.
