Before you start
- CAUTION! Check the backside (inside) of the chosen location before drilling or cutting.
Procedure
- Select a visible location where the EC-30 can be easily operated.
- Check the backside of the chosen location to verify nothing will interfere with drilling, cutting, fasteners, harness plug or enclosure.
- Determine feasibility of routing control wires from the genset to the remote; verify routing meets national and local codes.
- Wires must be protected from all hot, sharp, and abrasive surfaces.
- Cut out the mounting template and tape it square or level to the mounting surface.
- Use a center punch and hammer to punch marks for each fastener and at the cutout perimeter.
- Remove the template. Drill cutout starter holes at the four corners, cut between them and remove the cutout.
- Drill 1/8-inch diameter holes for the control panel fastening screws.
- Do not mount until wiring is complete.
