Electric Power Generation Installation and maintenance 5747 en - 2018.10 / a Dual plate D700 1.4. Safety devices and general safety instructions For the user's own safety, the dual plate D700 must be connected to approved earth terminals on the plate. The tools needed to make this connection are not included with the plate. -
Page 9: Use
Electric Power Generation Installation and maintenance 5747 en - 2018.10 / a Dual plate D700 1.4.2. Use D700 voltage regulators are components designed for integration in installations or electrical machines. When integrated in a machine, commissioning must not take place until it has been verified that the machine conforms with directive 2006/42/EC (Machinery Directive). -

Page 14: Setup Instructions
Electric Power Generation Installation and maintenance 5747 en - 2018.10 / a Dual plate D700 3. Setup instructions 3.1. Stator voltage and current measurement For the plate to work correctly, the stator voltage and current measurement on both AVRs must be identical. For generators with an unbalanced load, using different phases can result in a measurement fault and a bump in regulation on switching from one AVR to the other. - Page 15 Electric Power Generation Installation and maintenance 5747 en - 2018.10 / a Dual plate D700 Click "Yes" for the AVR which should be "active" when the plate starts, and "No" for the AVR which should be "Online". If the AVR is the "Master", the "Master regulator" box is checked. In both cases, the drawing on the right is updated with the appearance of a second D700.

Page 16: Checks Prior To Commissioning
Electric Power Generation Installation and maintenance 5747 en - 2018.10 / a Dual plate D700 On the "Inputs/Outputs" page • Inputs DI14 to DI16 are assigned as follows: • DI14: activation of "Maintenance" mode. This mode can be used to set the D700 offline. Redundancy between the two AVRs is then no longer active: only the second D700 is able to regulate. -
