DVR2000E/EC Hardware Installation- Connections -
The DVR2000E Installation, Operation, andMaintenance (IOM) Manual(GPN019 03/06),
Pages 29-32 provides you the information
necessary to connect the DVR2000E/EC
voltage regulator to your generator. Please
refer to this information for detailed
instructions and definitions of each terminal.
Ref: IOM, Page 26
NOTE: Be sure that the DVR2000E/ECis hard-wired to earthwith no smaller than 12 AWG copper wire attached to the
ground terminal on the rear of the unit case.

DVR2000E/EC Hardware Installation- Electrical Connection Notes -
1. In order to parallel with the DVR2000E/EC, a
current transformer (CT) MUST be installed in
the B-phase of the generator and connected to
the CT1 and CT2 inputs of the regulator.
2. If installing a CT, always confirm that the dot-
side is towards the generator as shown in theconnection diagrams.

DVR2000E/EC Hardware Installation- Electrical Connection Notes (Contd) -
3. To disable the droop circuit (Parallel Control),you MUST SHORT Terminals 52L and 52M.
This will be necessary to run the generator as
a stand-alone unit.
4. To disable the VAR/PF Control(available on
DVR2000EConly), you MUST SHORT
Terminals 52J and 52K. This will be necessary
to run the generator as a stand-alone unit if
using a DVR2000EC regulator.

5. The suggested 0.1 Ohm resistor shown for the
cross-current (reactive differential) connections
may need to vary. This burden resistorshould
have a value approximately (10) times thecross current loop resistance for proper
differential operation. The volt-ampere (VA)
capacity of the paralleling current transformersshould be considered after sizing the burden
resistor.

DVR2000E/EC Hardware Installation- Install Protective Cover -
NOTE: It is highly recommended that the protective cover be installed on the DVR2000E /
DVR2000ECwhenever power is applied to the DVR2000E / DVR2000ECas the heat sinks
on the rear-side of the DVR2000E / DVR2000ECare live when power is applied.
