MCB02-E5 3
(5) For power supply wires, use twisted wires with low voltage
drop.
(6) About 5 to 6 sec are required as the preparation time for
contact output after power on. Use a delay relay when the
output line, is used for an external interlock circuit.
(7) This instrument has no power supply switch nor fuses.
Therefore, install the fuse close to the instrument and the
switch, if required.
•
Fuse type ; Time-lag fuse
•
Recommended fuse rating : Rated voltage ; 250 V
Rated current ; 1 A
(8) For the current input specification, a resistor of 250
Ω
(
±
0.02%
±
10ppm, 0.25 W or more) must be connected between the
input terminals. This resistor must be provided by the
customer.
(9) Do not excessively tighten the terminal screws. In addition,
use the solderless terminal appropriate to the screw size.
(Screw size: M3x6, recommended tightening torque:0.4N
!

[4kgf
!
cm])
(10) To the instrument with power supply of 24V, please be sure to
supply the power from SELV circuit.
