Installation and Wiring
DA100/DS400/DS600(when using DC power terminal connecter)
This applies only to products with power supply 2 suffix code.
Follow the warnings below to avoid electric shock or damaging the instrument.
WARNING
• Connect the power wires after checking that the power supply is turned
off to prevent electric shock.
• To prevent fire, use wires with cross sectional area of 0.3mm 2 (22AWG)
or more.
CAUTION
• If you connect the + and - terminals in reverse on the DA100/DS400/
DS600, the internal fuse will be blown (You cannot replace the fuse by
yourself. The instrument needs servicing in this case). If there is a
possibility of reversing the polarity, insert a fuse (rating shown below) in
the wiring. This will lower the chances of blowing the internal fuse.
Fuse: 250 V/T2.5 A to T4A (time lag), 20 mm glass tube fuse,
I 2 t = 12.5 to 32
(Recommended: A1350EF (250 V/T2.5 A, I 2 t=12.5: SCHURTER:
FST0034.3121))
