4.1.3 Wiring Procedure
1) Put your fingers on the left and right (both sides) hooks of the transparent protective cover on the
power source terminal block. Pushing them in, pull the cover toward you.
2) Connect the power source electric wire, referring to Fig. 4.1.3. Connect the protective grounding to
the
terminal. Connect the non-grounding side of the power source to "L" terminal.
Connect the grounding side to the "N" terminal.
3) Attach the transparent protective cover.
4) Make sure that protective grounding is properly done.
Fig. 4.1.3 Wiring of Power Supply
CAUTION
(1) As an electric wire for the power source, use a 600 V vinyl insulated wire (IEC60227-3) or its
equivalent or above.
(2) Attach a ring-type solderless terminal with an insulation sleeve (for M3.5) to the end of the electric
wire.
(3) Connect a protective grounding (resistance: 100
or less, minimum diameter of a grounding
conductor: 1.6 mm) to the protective grounding terminal.
(4) If another instrument shares the protective grounding conductor, there may be interference caused
by noise coming from the grounding conductor. Do not share the grounding conductor with other
instruments.
(5) In order to comply with the requirements of safety standard EN61010-1, the recorder should have
one of the following as a disconnecting device, fitted within easy reach of the operator, and labeled as
the disconnecting device.
a) A switch or circuit breaker which complies with the requirements of IEC60947-1 and IEC60947-3.
b) A separable coupler which can be disconnected without the use of a tool.
c) A separable plug, without a locking device, to plug in a socket outlet in the building.
(6) This product has been designed to conform to EN61010-1, installation category
and pollution
degree 2.
(7) The main power supply should be used within a fluctuation range of
10 % of rated voltage.
(8) Transient current might flow to the main power supply when the power supply is turned on.
