Redbusbar CircuitSpy 80, Инструкция по установке и эксплуатации

Страница: 4 / 12

3 Installation
3.1 Mechanical Installation
3.1.1 Fixed Unit
CircuitSpy attaches to a conventional “top hat” DIN rail. The case consumes a length of 121mm of
the DIN rail. The width of the case is 45mm
. Plastic feet at the base of the CircuitSpy allow easy
installation and removal of the case using a flat blade screwdriver.
CircuitSpy should not be located within 100mm from a radio transmitter or heat radiating device.
3.1.2 Portable Unit
CircuitSpy incorporates two base mounted magnets such that it can be temporarily attached to
ferrous surfaces inside an electrical panel.
3.2 Electrical Installation
3.2.1 Fixed Unit
3.2.1.1 Power Supply
The required power supply for the operation of CircuitSpy is 12VDC with a maximum current capacity
of 0.1A, alternatively 24VDC with a maximum current capacity of 0.06A. Short circuit protection per
CircuitSpy by way of fuse or circuit breaker is not necessary. CircuitSpy incorporates an internal non-
replaceable fuse and reverse polarity protection.
3.2.1.2 Measuring Terminals
CircuitSpy measuring terminals should be connected in the following sequence:

GND
– Ground or Earth conductor

COM
– Common return conductor for all measuring terminals eg Neutral or 0VDC

1 to 8 - Measuring Terminals
CircuitSpy incorporates eight, line measurement terminals. Each conductor to be monitored is
connected to one feed-through terminal. The feed-through input terminal provides connection
functionality similar to that of a conventional DIN rail terminal. This approach simplifies retrofit
applications and reduces panel space in new installations.
Measuring terminals are not isolated from adjacent measuring terminals. However, input terminals
are isolated from the power supply terminals. The COM terminal provides a return path for all input
terminal current. Input terminals on the one module can be connected to different nominal voltages
provided that the connected voltages return to the same node and are deliberately bonded eg
240VAC and 110VAC neutrals and 24VDC and 12VDC negatives.
Measuring terminals incorporate overvoltage and over current protection. Depending upon the
application, wiring connecting CircuitSpy to the circuit node under test may or may not be protected
by upstream protection in the event of a wiring fault. Consideration should be given at the time of
installation whether additional fault protection devices are necessary at each connection point.
An electrical installation drawing for CircuitSpy is located in Appendix A.
