| Operation & Maintenance Instructions TOPAX L1/L4/L5 | General and Safety Instructions
All safety mechanisms and guards must be refitted and reactivated as the work is comple-
ted.
1.9 Unauthorized modifications and production of spare parts
The device may only be modified or converted in consultation with the manufacturer. Ge-
nuine spare parts and accessories authorized by the manufacturer ensure greater safety.
The use of other parts can void the liability for the subsequent consequences.
1.10 General notes of instruction!
Measuring cables must not be laid parallel or close to power supply or high-voltage current
lines. Interferences would mutilate the measurement. At close distances, power supply and
measuring lines may only cross at a 90° angle.
The admissible length of the measuring cables must be adhered to with regard to the sen-
sor used. It is of decisive importance whether high-impedance (e.g. pH value) or low-im-
pedance (e.g. free chlorine sensor) measurements are carried out. In the case high-impe-
dance measurements, make sure that the (plug) connections are clean and dry (plug) and
the lines do not become brittle due to sharp buckling. The screened cables normally used
for such measuring lines must be handled according to the prescribed quality. Screening
may only be connected to ground at one end of the cable (preferably at the controller).
Interface lines must be twisted and screened (see recommended cables).
IMPORTANT!
If possible, a continuous cable from sensor to measuring input should be used.
An extension of the cable by plugs or terminal socket increases the risk of
disturbances due to contamination, humidity or excessive transition resistances.
1.11 Scope of delivery
IMPORTANT!
Please unpack the dosing pump and ordered accessories with great care in or-
der not to miss any small parts. Immediately compare the scope of delivery with
the delivery note. The cause of any discrepancies must be determined.
1.1 Disposal
Should the device need to be permanently taken out of operation, please bear in mind that
it contains electrolytic capacitors and must therefore be disposed of accordingly.
