Power

Symphonie iPacks provide remote, autonomous power to the data logger system via either one or two
12 V, 2200 mAh batteries, which are continuously recharged via PV in the field and can be recharged
after office testing using a convenient wall charger (available from NRG).

SymphoniePRO should always be used with an iPack to provide long-term, autonomous operation (D-
cells are for backup only).

The iPack has additional input terminals for connecting a large external 12 V battery in case you intend
to use sensors with higher power requirements or keep the modem online for extended periods of time.

Two D-Cell batteries provide emergency backup for maintaining the logger’s core logging functions and
are also convenient for office testing when an iPack is not available.

Logger contains dedicated lithium battery which provides backup power to keep real-time clock running
in the event all other power sources go dead. This provides accurate and reliable timestamping when
the logger is powered up.
Physical

Wiring panel has large, easy-to-wire connection points.

Convenient “plug and play” SymphoniePRO Signal Conditioning Modules (P-SCMs) are pre-configured
for additional sensors.

SymphoniePRO uses industrial grade, non-volatile Secure Digital (SD) Cards for data storage.

The 4 line x 20 character display is easy to read and provides easy to understand real-time data and
configuration information.

Dedicated navigation buttons (up, down, left, right, home) plus a data entry keypad make the full-text,
menu driven display easy to use.

Wiring panel provides electro-static discharge (ESD) protection for each input channel. Tested to IEC
61000-4-5 for surge immunity.
1.6 Precautions
Grounding and ESD
Failure to ground the logger puts the logger and sensors at risk for electrostatic damage (ESD). Refer to
Appendix G for details regarding proper earth grounding and lightning protection.
Caution
The copper clad ground rod provides an electrical path for static electricity that builds up on the sensors to
dissipate to ground. Failure to use proper grounding protection can damage the equipment and will void the
warranty.
