Upgrading an IQ-1000 with an IQ-1000 II on a 120 VAC
control power system:
1. DO NOT JUMPER terminals 4 to 6 and 5 to 7.
2. Connect the high llne ofthe control power to terminal
4 and the grounded side of the control power trans-
former to terminal 7 (see Figure A).
3. Connect a separate earth ground from terminal 5 to
the system ground bus. This connection must be a
dedicated connection. DO NOT CONNNECT TERMI-
NAL 5 TO TERMINAL 7.
4. In order to disable the Incomplete Sequence func-
tion, jumper terminal 4 to 10 and terminal 6 to
9.
These jumpers are installed at the factory. If the
Incomplete Sequence function is not to be disabled
then see Figure A for wiring detalls.
5. TERMINAL 6 IS ONLY TO BE USED FOR THE
JUMPER CONNECTION TO TERMINAL 9.
6. TERMINAL 5 IS ONLY TO BE USED FOR A
DIRECT CONNECTION TO THE SYSTEM
GROUND BUS. DO NOT USE TERMINALS AS A
GROUNDING POINT FOR ANY OTHER DEVICE.

II UPGRADE
Upgrading an IQ-1000 with an IQ-1000 II on a 240 VAC
control power system:
1. DO NOT JUMPER terminals 5 to 6.
2. Connect the high line of the control power to terminal
4 and the grounded side of the control power trans-
former to terminal 7 (see Figure A).
3. Connect a separate earth ground from terminal 5 to
