3. Installation
3-1 Environmental requirement
Be sure to use this in the following environment
• Ambient temperature: 0–+50 C
• Humidity: 35–85%RH
3-2 Mounting unit
Make sure to fix the pump firmly. Insufficient
mounting of the pump could fall itself and cause
injury.
Be sure to fix the pump against the vertical and
flat surface, which can sustain its weight
sufficiently. Mount and fix the pump firmly using
four (4) M8 bolts through φ9 holes.
LUBE recommends anti-vibration
rubber to be applied when the pump is
exposed to vibration.
Be sure to allow necessary space as marked in the
chart below for operation and maintenance
around the pump.

3-3 Wiring
For the power supply, use a 24-VDC stabilized power
supply.
For wiring, see the figure below. Make sure that the
positive (+) and negative (-) terminals are connected
correctly. If the positive (+) and negative (-) terminals
are connected incorrectly, the pump will not operate.
If an external lead wire from the 24-VDC power supply
is likely to come in contact with your hand, machine
exterior or any other surrounding object, use an
insulated wire of less than 30 m.
The LED of the DIN connector (24 VDC input) lights when the pump starts.
Only qualified personnel for electrical work should
connect wiring.
