Electromagnetic Compatibility
This unit has been designed to provide protection against
EM (electro-magnetic) interference in line with requirements
of CE and other regulations. Precautions necessary to
provide proper operation of this and adjacent equipment will
be installation dependent and so the following can only be
general guidance:-
• Avoid routing wiring to these products alongside cables
and products that are, or could be, a source of
interference.
• Where required, the auxiliary supply to the unit should
not be subject to excessive interference. In some
cases, a supply line filter may be required.
• To protect the product against incorrect operation or
permanent damage, surges and transients must be
controlled. It is good EMC practice to suppress
transients and surges at the source.
• Connecting leads may require the fitting of RF
suppression components, such as ferrite absorbers or
line filters
•
It is good practice to install sensitive electronic
instruments that are performing critical functions in
EMC enclosures that protect against electrical
interference causing a disturbance in function.
Commissioning
The units are calibrated at the factory for full accuracy. No
further adjustments are required except to check the zero
position.
With the meter in the intended attitude, adjust the centre
slotted adjuster for scale zero without electrical input signal.
It is
recommended that after installation, test signals are applied
to confirm correct indication and that, where applicable, CT
phasing is correct and voltage and current connections
match. Bezel
