Safety Instructions
High voltage hazard!
The Logger4000 should be reliably ground. Never touch the AC power supply
port "AC IN 100–277V,0.48A" and MPLC communication port "L1、L2、L3"
when the device is powered on.
High voltage hazard! Danger will be caused by touching the MPLC
communication port immediately after powering down. Wait at least 30s to
have the capacitor discharge completely.
Do not enable the rated DC input and AC input to supply power at the same time.
Otherwise, the power supply may be abnormal.
The rated voltage of the slow-blow fuse is 250V and the rated current is 5A. The
fuse is not replaceable.
Incorrect wiring will cause device damage or even personal injury.
All cables must be intact, well insulated, appropriately dimensioned, and firmly
connected.
