There is a label on the HCU showing the connectors with marking and color coding. IMPORTANT! It is very important to reduce stress from the cables on the connectors. We recommend that all cables are fixed to the HCU with strain reliefs.
The standard bus cable is available in the following lengths: 5 m (16 ft), 7 m (23 ft), 9 m (30 ft), 11 m (36 ft), 13 m (42 ft) with socket connectors (female) at both ends. NOTE! The cable has female connections on both ends and cannot be used as an extension. Extension cables are available in the following lengths: 1.5 m (5 ft), 3 m (10 ft), 5 (16 ft), 7 m (23 ft), 9 m (30 ft), 11 m (36 ft) and with a pin (male) and a socket (female) connectors. IMPORTANT! The red and green marking strips indicate port and starboard respectively. In a twin engine installation, only the appropriate color marking strips should remain on the cable. The other markings shall be removed.

Mount strain reliefs as shown in the illustration above. IMPORTANT! Always make sure that the locking mechanism between the male and female connectors closes with a click. This guarantees a water-tight correct closure.
