7.6.3 Electrical connection of Cable Extender Box
The extender box is built up with transient transorbs diodes, making it possible to extend the cable between
ULTRAFLOW
® and MULTICAL ® with up to 30 m in total, while the cable length without the extender box can be
maximum up to 10 m.
Fix Cable Extender Box to the wall or the like close to ULTRAFLOW ® . Connect the 3 wires in the cable from
ULTRAFLOW ® to one of the terminals in Cable Extender Box. You can select any of the terminals. Use a 3-wire
extension cable with a length of up to 27.5 m with the same wire diameter and of the same quality as the cable
from ULTRAFLOW
® , and connect the 3 wires to the other terminal in Cable Extender Box. Connect the opposite end
of the extension cable to the terminal (V1) in MULTICAL ® . Use the following combination when connecting the wires:
10: Yellow, 9: Red and 11: Blue. This colour combination applies to both Cable Extender Box and MULTICAL ® .
Perform a function check, and complete by sealing Cable Extender Box with the included void-labels of the utility.
