I have attached a labeled picture of the heater. The long set of white wires are the power cables, the short white cables are extensions to be used to chain more than one heater together, in parallel, to a single supply channel. If these are not used, the conductors

 will be covered.<br>

The cable ends are just stripped back, we have not specified the connector yet. The connection to power distribution will determine how the cables are terminated.
