Caution
1. In the interest of safety and functionality of this product must be installed by a qualified engineer,
abiding by any local regulations.
2. Voltages dangerous to human life are present at some of the terminal connections of this unit. Ensure that
all supplies are de-energised before attempting any connection or disconnection.
3. These products do not have fuses, therefore external fuses must be used to ensure safety under fault
conditions.
Mounting of the Meter is featured with easy “Clip- in”
mounting. Push the meter in panel slot (size 92 x92 mm), it
will click fit into panel with the four integral retention clips
on two sides of meter. If required, additional support is
provided with swivel screws as shown in figure.
The front of the enclosure conforms to IP54. 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 Meter should be mounted in a reasonably stable
ambient temperature and where the operating
0
temperature is within the range 0 to 50 C. Vibration
should be kept to a minimum and the product should not
be mounted where it will be subjected to excessive direct
sunlight.

3.1 EMC Installation Requirements
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 : It 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
for a period of greater than 5 seconds to restore correct operation.
The Current inputs of these products are designed for connection to systems via shunt only
4. ESD precautions must be taken at all times when handling this product.
