Electrical connection of Cable Extender Box
The Cable Extender Box includes transient transorb 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 Cable Extender Box can be maximum up to
10 m.
Mount 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 two 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 or V2) in MULTICAL®. Connect the cables according to the following combination: 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 or the seal labels of the utility.
