insTallaTion & Wiring:

Note:  Although  the  FM1D  models  contain  some 

degree  of  spike  and  electrical  noise  protection,  as 

with all electronic devices, these units can be affect-

ed by electrical noise. Therefore, it is recommended 

that they be powered from a voltage source that has 

no switching devices or inductive loads connected.

1. Check the input and output ratings marked on 

the unit to make sure this product is suitable for your 

supply voltage, load, and application.

2. Disconnect supply power prior to installation to 

prevent electrical shock.

3. Instal  in accordance with al  applicable National 

and Local electrical code requirements.
