Wiring and alarm
Install a fuse between the power supply and the product is strongly recommended!
The electrical circuit diagram of the lubrication unit is affixed inside the unit and can be
accessed by removing the cap.
Remove the cap (Fig.5) and inside you can see terminal plate and cable gland nut. Loosen
cable gland (Fig.6) and then insert cable through the cable gland hole (Fig.7) to wire up. Fix the
cable gland to the housing.
Wiring must comply with the electrical circuit diagram (Fig.8) of the lubrication unit
affixed inside the unit.Otherwise, property damage or serious injury can occur.
Level switch and pressure switch are strongly recommended to assemble for fault
monitoring and preventing chance of property damage or serious injury. In the model design
with a control unit, the electrical connection to the monitoring units such as pressure switches
and float switches is established inside the lubrication unit directly to the connectors on the
electronic control unit. Depending on the control unit's model design, a signal line for fault
monitoring can be run outwards to connect to the machine control unit via a cable fitting
mounted on the lubrication unit.

(Fig.7) can be connected to external alarm device or
CNC abnormal input(250VAC,3A).
After the electrical connection is finished, tighten the cable gland (Fig.9) and fix the cover.
Then turn on the power and the power indicator on the panel for YET-D will lamp if the
electrical connection is correct.
