Technical Features Of The Fan Motors Used - Modine ECO KCE Serie Manual Tecnico

Connect high speed motors (∆) - 400 V/3/50 Hz and low speed (Y) - 400 V/3/50/Hz
∆ connection (preset)
Motor no. 1
( * ) Internal thermal contact protection
The thermal contacts are temperature sensing switching elements built directly into the windings of the motors. They interrupt
an electrical contact when maximum sustained temperature has been reached. The thermal contacts must be connected to the
control circuit of the mains contactor to prevent automatic reconnection of the motor in the event of a fault.
WARNING!
To avoid damage to motor strictly follow the electric schemes shown.
Before using motor speed control systems verify the compatibility with the motors; non-compatible systems may damage the
motors or increase the noise level; the manufacturer will not be responsible for model performance with speed control systems.
