Wiring - Three Phase
Apply power to the SGDH and MP940 simultaneously. If the SGDH is not powered
within 10 seconds after turning power ON to the MP940 (or vice versa), the units will
not communicate with each other. Note: For maximum noise immunity, connect the
FG to a ground terminal on the sub-panel, or to the ground terminal on the SGDH.
