General installation guidelines 

-

  It is recommended to install the unit in a hallway to limit the VSD-1MC-20(40) 

exposure to noxious gases. 

-

  In order to avoid condensation problems inside the VSD-1MC-20(40), it is 

recommended to install the module on an inside wall. If it is not possible, use 
spacers to have an air gap between the wall and the module. 

-

  The VSD-1MC-20(40) should be installed in easy-access location but away from 

damaging elements (heat, cold, water, direct sunlight…). 

-

 

Do not drill the face, the side, the top or the underside of the module. 

-

  Do not install the VSD-1MC-20(40) near high-voltage equipment, power supply or 

transformer.

 

 

Wiring Procedure 

1.  Open the VSD-1MC-20(40) module enclosure. 

2.  Verify the technical specifications to know which wire to use. 

3.  Connect the equipment to the 2 wires identified as H1 and H2 as shown in figure 

1. 

IMPORTANT: The variable output requires the same phase and same voltage as the 
controller to operate. 

4.  Connect the power source to the 2 black terminal block identified as LINE as 

shown in figure 1. 

5.  Set the JP1 jumper (refer to figure 2 for the location of the jumper) to determine 

the correct input type. The two types of input are: 0-20 mA (jumper on the 2 left 
pins) and 0-10 Volts (jumper on the 2 right pins). 

6.  Connect the 0-10 V or the 4-20 mA signal to the 2 green terminal block identified 

as INPUT as shown in figure 1. 

IMPORTANT: Low-voltage and high-voltage wire must be passed through different 
conducts at least 1 foot (30 cm) apart. If low-voltage and high-voltage conduits must 
be crossed, the crossing must be at a 90-degree angle. 

7.  Make sure that the Voltage Selector Switch is set to the correct voltage before 

powering up the VSD-1MC-20(40) (refer to figure 2 for the location of the 
Voltage Selector Switch). 

8. Power up the VSD-1MC-20(40) module. Verify that the module operates 

correctly. 

9.  Close the VSD-1MC-20(40) enclosure. Don’t forget to put a security screw or a 

padlock.
