As the front of the enclosure conforms to IP54 it is protected from water spray
from all directions, additional protection to the panel may be obtained by the
use of an optional panel gasket. The terminals at the rear of the product
should be protected from liquids.
The instrument should be mounted in a reasonably stable ambient
temperature and where the operating temperature is within the range
0
-10 to 55 C. Vibration should be kept to a minimum and the product should
not be mounted where it will be subjected to excessive direct sunlight.

4.1 EMC Installa tion
This product has been designed to meet the certification of the EU directives
when installed to a good code of practice for EMC in industrial environments,
e.g.
1.
Screened output and low signal input leads or have provision for fitting
RF suppression components, such as ferrite absorbers, line filters etc., in
the event that RF fields cause problems.
Note:I t is good practice to install sensitive electronic instruments that are
performing critical functions, in EMC enclosures that protect against electrical
interference which could cause a disturbance in function.
2.
Avoid routing leads alongside cables and products that are, or could be,a
source of interference.
3.
To protect the product against permanent damage, surge transients must
be limited to 2kV pk. It is good EMC practice to suppress differential
surges to 2kV at the source. The unit has been designed to automatically
recover in the event of a high level of transients. In extreme
circumstances it may be necessary to temporarily disconnect the
auxiliary supply fora period of greater than5 seconds to restore correct
operation.
4.
ESD precautions must be taken at all times when handling this product.
4.2 Case Dime nsion
The Current inputs of these products are designed for connection in to
systems via Current Transformers only, where one side is grounded.
4.4 Auxilia ry Sup ply
Meter should ideally be powered from a dedicated supply, however
it may be powered from the signal source, provided the source remains within
the limits of the chosen auxiliary voltage.

4.3 Wiring
Input connections are made directly to screw-type terminals with indirect
wire pressure. Numbering is clearly marked in the plastic moulding. Choice of
cable should meet local regulations. Terminal for both Current and Voltage
inputs will accept upto 3mm x 2 diameter cables.
