Page 5: Product Overview
3 Product Overview The SS9007 Mini CT Meter is a compact power metering and load switching device that can be used to monitor and control single phase electrical loads. Designed to sit on a standard switchboard DIN rail, the SS9007 has the same form factor as a standard Miniature Circuit Breaker, and accepts a wide range of external Current Transformers. -

The radio environment at the location of installation may be tested to ensure the new device will be able to connect to the existing ZigBee network. For more information on radio environment test equipment and procedures, please contact Saturn South. There are two stages to device installation: 1. - Page 8 Figure 1: Side panel markings for SS9007.3 terminals IMPORTANT: • Ensure the source of the reference phase is isolated before performing these steps. • The SS9007 Mini CT Meter is not rated as a protection device, and must be installed downstream of a readily accessible approved protection device rated to 20A or less in TT and TN power distribution systems.
- Page 9 6. Connect the output of a MCB, RCD, or other protection device to the “Live” (L) terminal of the Mini CT Meter, and a neutral line to the “Neutral” (N) terminal. The protection device used for this purpose need not necessarily be on the same circuit that the device will be monitoring (i.e.

- Page 11 WHITE”), and two SWITCH terminals are marked on the side and end panels of the device enclosure. If the circuit being monitored is connected to a protected neutral (e.g. via an RCD), ensure that the Mini CT Meter is also connected to the same protected neutral, and not to the main neutral link.
- Page 12 IMPORTANT: • If multiple SS9007s are being used to monitor a polyphase phase load, care must be taken to ensure each SS9007 is powered by the corresponding phase. Figure 6: Example three phase installation for a TT or TN power distribution system. Note that each Mini CT Meter is powered by a circuit that is on the same phase as its corresponding CT.

To complete the installation process, the SS9007 Mini CT Meter must be joined to an existing ZigBee network. The following instructions apply specifically to networks based on the Saturn South ESBox Ethernet-ZigBee Gateway device, however the process will be very similar when using third party ZigBee coordinators. -
Page 14: Switching
6 Switching The two terminals marked 'SWITCH' (‘SW’) on the SS9007.3 Mini CT Meter are connected internally to an isolated DIAC switch with a 100mA current limit. The internal DIAC is typically used to control a third-party external to control loads directly from the switchboard. -
Page 15: Metering
Current is measured using a clip-on current transformer (CT), with nominal primary current ratings of 40A, 120A, and 200A available as standard. Each individual Saturn South meter is calibrated in the final stage of the production process. The calibration procedure matches each device to a particular CT variant, meaning that measurements will not be accurate if a device calibrated for a 120A CT is used with a 40A CT. -
