7. Maintenance

In normal use, little maintenance is needed. As appropriate for service conditions, isolate 

electrical power, inspect the unit and remove any dust or other foreign material present.  

Periodically check all connections for freedom from corrosion and screw tightness, particularly if 

vibration is present. 

The front of the case should be wiped with a dry cloth only. Use minimal pressure, especially 

over the viewing window area. If necessary wipe the rear case with a dry cloth. If a cleaning 

agent is necessary, isopropyl alcohol is the only recommended agent and should be used 

sparingly.  Water should not be used. If the rear case exterior or terminals should be 

contaminated accidentally with water, the unit must be returned to Autometers Systems Ltd for 

inspection and testing. 

8.  Installation

The meter may be mounted in a panel with a maximum thickness of 3 mm. Leave enough space 

behind the instrument to allow for bends in the connection cables. The unit is intended for use 

in a reasonably stable ambient temperature within the range -25°C to +55°C. Do not fit the 

meter where there is excessive vibration or in excessive direct sunlight.

Please note terminal covers should be fitted and sealed.  

See connection diagram page 21, 22.

8.1 Safety

The unit is designed in accordance with IEC 61010-1:2010 – Permanently connected use, Normal 

condition. Installation category III, pollution degree 2, basic insulation for rated voltage. 

9. Electrician.

The HT-1095 panel meter should only be installed by a fully qualified electrician who has 

knowledge of electricity meters connected with current transformers.

It is the installer who is fully responsible for the safe installation of this meter. It must be 

installed to meet the current electrical regulations concerning installation of panel meters. 

10.  EMC Installation Requirements

Whilst this unit complies with all relevant EU EMC (electro-magnetic compatibility) regulations, 

any additional 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 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 transients and surges 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 10 seconds to restore correct operation.

Screened communication 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.

WARNING

 

 

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-energized 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.

This unit is not intended to function as part of a system providing the sole means of 

fault protection - good engineering practice dictates that any critical function be 

protected by at least two independent and diverse means.

The unit does not have internal fuses therefore external fuses must be used for 

protection and safety under fault conditions.

Never open-circuit the secondary winding of an energized current transformer.

This product should only be operated with CT secondary connections Earthed.

If this equipment is used in a manner not specified by the manufacturer, protection 

provided by the equipment may be impaired.

Auxiliary circuits (communication & relay outputs) are separated from metering inputs 

and 110-400V auxiliary circuits by at least basic insulation. Such auxiliary circuit terminals 

are only suitable for connection to equipment which has no user accessible live parts. The 

insulation for such auxiliary circuits must be rated for the highest voltage connected to 

the instrument and suitable for single fault condition. The connection at the remote end 

of such auxiliary circuits should not be accessible in normal use. Depending on 

application, equipment connected to auxiliary circuits may vary widely.
