3.6 General Instructions
1. Unscrew the cap on the unit.
2. Loosen the cable gland located on the side of the unit.
3. Feed the cable through the conduit opening.
Note: Use a standard signal cable size.
4. Retighten the metal cable gland to meet IP67 and to relieve any stress on the wire.
5. Verify that a voltage between 12 and 28 V DC is across the terminals and -.
Note: This is the voltage that appears across the DewPro terminals, not necessarily the power supply voltage due
to voltage loss in wire length, displays, and indicators.
6. In order to meet EMI/RFI immunity, a two-wire shielded cable with a common foil shield layer is being used to
power the MMR30. Removing the insulation by 3” allows users to pull back the foil, clamping it in between the
metal cable gland. You must connect the ground wire to the internal grounding screw.
