3.3.1
Wiring for Power Supply and Grounding
This is for supplying power of voltage and frequency meeting the specification of the analyzer
and for grounding the converter case.
Connect the terminals L1 and L2 of the converter to power supply with a two-conductor cable of 6
to 12 mm finished O.D..
When the analyzer is equipped with arrestors (when option code “/ARS” is specified), connect
terminals L1 and L2 to the power terminal box (a circuit breaker is incorporated).
Refer to Figures 3.5 to 3.7.
CAUTION
The converter does not have a power switch. A double-pole switch should be installed in the
power line. A power switch for the converter is necessary to prevent electric shock or damage
to the instrument when inspection or maintenance of electric system is performed with power
supplied.
Treat the end of cable to be connected to the converter terminal in the following manner:
(1) Strip of the insulation covering from the cable at its end approx. 80 mm.
(2) Attach to the tip of the conductor a crimping type terminal lug which fits an M4 screw.
For grounding, use the grounding terminal marked “ ” at the bottom of the converter case.
Provide grounding by connecting the end-treated (for sufficient conduction) grounding lead to the
M5 screw of the grounding terminal (grounding resistance must be 100 Ω or less).
NOTE
When the grounding terminal of the converter case cannot be used, connect the grounding lead
to terminal G (M4 screw) inside the converter and ground the lead at the power supply. For this,
use a two- or three-conductor shielded cable for power supply and grounding wiring.
