The product should be panel mounted using the mounting
hardware supplied. Consideration should be given to the
space behind the unit to allow for bends in the connecting
cables. The terminals on the meter rear should be
protected from liquids.
The unit must not be mounted where it can be subjected
to direct sunlight, and vibration should be kept to a
minimum. Connection wires must be sized to comply with
local regulations and must be terminated on tags suitable
for screw connection. The product has no internal fuse,
therefore; external fuses must be used for safety
protection under fault conditions.

SAFTEY STANDARDS
WARNING
SAFETY STANDARDS
This product complies with:
International standard: IEC1010-1
For UK: BS EN 61010-1 (IEC1010-1)
Fusing and connections
This unit must be fitted with external fuses in voltage
supply lines. Voltage input lines must be fused with a
quick blow fuse 1A maximum. Choose fuses of a type
and with a breaking capacity appropriate to the supply
and in accordance with local regulations.
During normal operation, voltages hazardous to life
may be present at some of the terminals of this unit.
Installation and servicing should be performed only
by qualified, properly trained personnel' abiding by
local regulations. Ensure all supplies are de-
energised before attempting connection or other
procedures.
Terminals should not be user accessible after
installation and external installation provisions must
be sufficient to prevent hazards under fault
conditions.
Never open circuit the secondary winding of an
energised current transformer.

SAFETY SPECIFICATION
Electromagnetic Compatibility
This unit has been designed to provide protection against EM
(electro-magnetic) interference in line with requirements of
EU 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:-
Permanently connected use.
Normal condition
Basic insulation
Installation category II
Pollution degree 2
This product is intended as part of a permanent
installation.
Low Voltage Directive BSEN 61010-1
For use in altitudes up to 2000m
Temperature 0-40 degree C Maximum relative humidity
80% for temperature up to 31º C decreasing linearly to
50% RH at 40ºC
Operating temperature to retained stated product
accuracy 0-40ºC
Avoid routing wiring to this unit alongside cables and
products that are, or could be, a source of interference.
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, surge transients must be controlled.
It is good EMC practice to suppress differential surges to
2kV or less at the source. The unit has been designed
to automatically recover from typical transients, however
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.
Screened communication and small signal leads are
recommended and may be required. These and other
connecting leads may require the fitting of RF
suppression components, such as ferrite absorbers, line
filters etc., if RF fields cause problems.
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.
