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.
K1M/1 K5M/13
K1M/3
K1M/5
K1M/3 K1M/5
K2M/1 K5M/13
