Weka HS50 Emma Instructions De Service page 12

4.1.2 400 3 ~
Connect the HS50 via the frequency converter FU6D and via the adapter cable only on a properly
earthed shockproof socket. If required use only high quality extension cords with sufficient cross section.
Up to 100m length - 4G2,5 quality, e.g. H 07BQ-F or H 07RN-F
Take care that the extension cord is not rolled up on use for reaching a sufficient heat
removal. Consider that the HS50 takes the maximal power from the electrical mains.
Therefore do not connect other users to the concerning fuse, as the mains and the fuse
will then be overloaded. Please take care that the HS50 is only connected to an earthed
16A CEE socket. If you operate the machine at a higher assured socket, you risk in case
of any fault the total burning of the electronic.
According to the relevant regulations machines in the commercial sector may be operated
only by means of a building power distribution system. Ensure that a residual current
circuit breaker of type B, or B + is integrated, since an FI type A can fail in the event of a
fault. By the high leakage current the machine can electrify when touched, if the ground
line is not connected correctly. In this case absolutely disconnect the mains plug
immediately and check the ground wire.
HS50 and FU6D can be used at a generator or a transformer provided by the construction site, if
following conditions are kept:
- operating voltage within +5% and –10 % to nominal voltage
- integrated automatic voltage controller with start amplification
- frequency 50 – 60Hz; max. 65 Hz
- AC voltage, power output at least:
230V ~
400V 3~
Do not use any other devices at the generator/transformator at the same time. The switching on and off
of other devices can cause undervoltage and / or over voltage peaks that can damage the machine.
4.2 Water connection
Now connect the frequency converter vie the plug-in nipple to the water supply. Connect the FU6D with
the hand saw via a water hose. The ball valve must at any time be on the side of the water supply.
Attention: water pressure max. 3 bar. Water may only be connected to ball valve, as
otherwise a damage on the casing may appear by upcoming water pressure.
Please use a GARDENA coupling as the connecting piece to the machine and the frequency converter.
This can be obtained from a garden center or builders' merchant made of platics. A water coupling of
brass of high quality can be received directly from WEKA.
Use only clean water, as dirty water will considerably disturb the heat exchange on the cooling surface
and thereby the motor can be totally damaged.
Else the seals wear out very quickly.
If water exits of the leakage hole at the gear, the water seals have to be exchanged
immediately. This shoud only be done in an authorized repair station. Attention: Under
full load there are at least 1 l of water per minute required. Open the ball valve after use,
so that the cooling gap can empty. This is mainly required in the cold season - danger of
frost.
4.3 Dry sawing
If you intend to saw dry, the motor still has to be cooled suffiently with water. On the side of the gear
there is a valve. Turn the grip downwards and connect a hose to the plug-in nozzle via a DN 7,5 coupling
via which the water can flow out.
4.4 Cutting with a guide rail
Attach the guide rail to the surface to be cut with at least two dowels. The HS50 can be inserted in the
guide rail by means of the recessed area in the frame of the guide rail.
