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 capacity
and power supply, following resistance values (see table below)
should be measured. ALWAYS measure the resistance on the
contactor clamps K1M, K2M, and K5M.
