Use 8 square mm cable with M5 wire terminal.
CAUTION
Be sure that the output of the step down transformer is AC100V ±10%. Irregular connection causing higher voltage will result serious damage to the equipment.
Alternately the step down transformer may be put at the input of
In the case, connect the input of the transformer to the main breaker of the site power supply. Connect the out put to the Main breaker (ELB) of

In both of above cases, ground the instrument at a grounding resistance lower than 100 ohms. The grounding terminal must not be common to other electric equipment, i.e. exclusive grounding should be provided.
NOTICE
The instrument provides one of following two types of Main ELB.
(1) For using with 200 to 240V power line
Leakage current breaker (with key lock, CE/UL conforming)
Capacity | : 6.4kVA |
Maximum current | : 32A |
Sensitive current | : 30mA |
: 25kA | |
(2) For using with 100V power line |
|
Leakage current breaker(without key lock, CE or UL not conforming)
Capacity | : 5kVA |
Maximum current | : 50A |
Sensitive current | : 30mA |
: 5kA |
Instruments shipped to USA and Europe area and ordered to meet S2 guideline provide the type of above (1).
