SAFETY CONSIDERATIONS
This device is marked with the international Caution, risk of danger symbol. It is
important to read this manual before installing or commissioning this device as it
contains important information relating to Safety and EMC (Electromagnetic
Compatibility).
Unpacking & Inspection
Unpack the instrument and inspect for obvious shipping damage. Do not attempt
to operate the unit if damage is found.
This instrument is a DIN rail mount device. Installation of this instrument should
be done by Qualified personnel. In order to ensure safe operation, the following
instructions should be followed.
This instrument has no power-on switch. An external switch or circuit-breaker shall be
included in the building installation as a disconnecting device. It shall be marked to indicate
this function, and it shall be in close proximity to the equipment within easy reach of the
operator. The switch or circuit-breaker shall not interrupt the Protective Conductor (Earth
wire), and it shall meet the relevant requirements of IEC 947–1 and IEC 947-3 (International
Electrotechnical Commission). The switch shall not be incorporated in the mains supply cord.
Furthermore, to provide protection against excessive energy being drawn from the mains
supply in case of a fault in the equipment, an overcurrent protection device shall be installed.
• The Protective Conductor must be connected for safety reasons. Check
that the power cable has the proper Earth wire, and it is properly connected. It is
not safe to operate this unit without the Protective Conductor Terminal
connected.
• Do not exceed voltage rating on the label located on the top of the instrument
housing.
• Always disconnect power before changing signal and power connections.
• Do not use this instrument on a work bench without its case for safety reasons.
• Do not operate this instrument in flammable or explosive atmospheres.
• Do not expose this instrument to rain or moisture.
• Unit mounting should allow for adequate ventilation to ensure instrument does
not exceed operating temperature rating.
• Use electrical wires with adequate size to handle mechanical strain and power
requirements. Install without exposing bare wire outside the connector to
minimize electrical shock hazards.
EMC Considerations
• Whenever EMC is an issue, always use shielded cables.
• Never run signal and power wires in the same conduit.
• Use signal wire connections with twisted-pair cables.
• Install Ferrite Bead(s) on signal wires close to the instrument if EMC problems
persist.
INSTALLATION
1. Unpack and verify that all equipment has been received. If there
are any questions about the shipment, contact the service
department nearest you.
2. Cut or punch a hole in the panel where you want the meter to go.
3. Remove the lens by inserting a paper clip or small flat screwdriver
into the rounded corner of the lens and lift out.
4. Remove the two mounting screws from both sides of display. Pry
both sides of the mounting clamp out and down to remove it from
the case.
5. Insert the meter into the panel cutout and reinstall the mounting
clamp from the rear.
6. Reinstall the mounting screws to secure the meter into the panel.
Do not overtighten the screws.
7. Pop the lens back in, making sure the dull side of the lens faces
towards you.

CAUTION: Do not connect ac power to your meter until you
have completed all input and output connections. Failure to
do so may result in injury! This device must only be installed
electrically by specially trained electrician with
corresponding qualifications. The main power input to the
unit as well as the AC input signal to be measured must
agree with the wiring instruction.
The meter is factory set to the power specified by the customer at the
time of ordering. The voltage is printed on the label under Input
power.
To connect power to the unit, attach wires, as shown from the ~AC
power cord to the orange 3-pin female connector that is supplied with
the meter. Plug the female connector into the orange P1 (male)
connector at the rear of the meter.
