ELECTRICAL CONNECTIONS
Access to the High Voltage and Low Voltage Connection Strips can be made by removing the appropriate knockouts
on the back panel of the heater. All connections should be secured using an appropriate cord anchorage. One cord
anchor is supplied with the heater for securing the mains supply to the unit. If additional controls and ancillaries are to
be used, the appropriate knockout should be removed and an anchor such as RS Components part number 607-897
plus locking nut 607-910 should be fitted.
If a knockout is removed by mistake, the resulting hole must be blocked with an appropriate anchor, plug or
grommet to prevent accidental access to the live parts within the heater.
