4.3 Control Cables from the 5kW Electrical Heater Module
1. The wiring of the 5kW electrical heater contacts must not be routed near power cables in order to avoid
electromagnetic disturbances. Use shielded cable with twisted pairs (shielding grounded on the 5kW
electrical heater side only) - min 0.5mm
2. When extended wire lengths are required between the 5kW Heater and the Heat Pump Unit Baxi
recommends the use of colour coded wiring to reduce the risk of wrongly made connections.
