6.4 Power supply and switch-on
Important!
Be careful to compare the data of the local voltage supply with
that given under "Technical data". Operating voltage must
amount to 24 VDC
10%.
Important!
Lay the power supply cable such that it cannot be torn off inad-
vertently.
Important!
Work on electric facilities may only be performed by skilled elec-
tricians in conformity with DIN VDE 1000-10.
Connect the pump unit to the voltage supply.
Ground the pump unit through the potential connection by means of a threaded M4 screw.
Check the electric connections for correct installation prior to commissioning.
Caution!
Work on electric facilities implies danger to life!
6.5 Commissioning
The pump unit‘s functionality has been checked in the factory. Hence, it is ready for opera-
tion and can be connected to a local voltage supply.
Important!
Note the safety instructions contained in the "Power supply and
Switch-on" section.
First fill lubricant and then start the pump unit, in every case
(Minimum filling level, see chapter 7.2.).
Commissioning procedure:
a) Filling the pump with lubricant
The pump units may be operated with clean oil or grease from original pack-
ages only!
The initial filling with grease must be done through the filler nipple in order to
fill the pump’s suction chamber safely.
Hint:
For the pump’s initial filling with grease, we recommend to fill it with
transmission oil up to the stirring wing in order to ensure a speedy and
better bleeding.
When selecting the transmission oil, however, proper compatibility
with the lubricant used needs to be ensured!
