For configuration of the backup heater, see "4.2.2 Quick wizard:
Standard" on page 13.
2
Fix the cable with cable ties to the cable tie mountings.
3
Configure the user interface for the respective power supply.
See "4.2.2 Quick wizard: Standard" on page 13.
During connection of the backup heater, miswiring is possible. To
detect possible miswiring, it is highly recommended to measure the
resistance value of the heater elements. Depending on the different
backup heater types, following resistance values (see table below)
should be measured. ALWAYS measure the resistance on the
contactor clamps K1M, K2M, and K5M.
