4 Installation
• If the outer jacket of the cable is damaged, then replace the cable.
• The cable must not be damaged and must not have indentations or be embossed at the
cable entry.
• If the cable has been used before, then a short piece must be peeled off when refitting it.
This prevents the cable entry seal sleeve from closing around the cable at the same
point.
• The cable must not be exposed for long periods to direct UV light. The cable ends must
be protected from water during storage.
Cable handling
To install cables, follow these requirements:
• Start at the pump and carefully roll out the cable.
• When pulling the cable, do not exceed the maximum permissible tensile force.
• Do not bend the cable to a radius smaller than the recommended minimum bending
radius.The recommended minimum bending radius is 10 times the diameter of the cable.
• Make sure that vehicles cannot run over the cable.
• All cables lose flexibility at lower temperatures. Use extra care when the cable is cold.Do
not work with a cable whose temperature is below –30°C (–22°F).
