Recommendations for using Powermesh Switches with Inductive loads

When wiring a Powermesh Multi Purpose switch ( PMMPSxxx) to an inductive load such as an exhaust fan, contactor, etc., the use of an RC Suppressor module is highly recommended as a safeguard. The RC Suppressor will normalise current spikes and maintain a more stable voltage level that can be caused by these inductive loads which could potentially damage the switch .

Please note this is NOT DIY and installation must be carried out by a LICENSED ELECTRICIAN to local wiring regulations. Failure to follow these instructions can result in serious injury or death

Wiring Instructions:

Wire the suppressor module to the desired switch circuit channel behind the switch as per the diagram below.
