IG – Main switch
The chiller carries no current after it has been turned off with the main switch. The switch is located on
the door of the switch cabinet.
MTC – Motor protection switch for compressor
If the motor current increases beyond the set value or if there is a short circuit, the motor protection
switch turns off and interrupts the current supply. The motor protection switch has to be turned on
manually after the cause of the malfunction has been eliminated. The motor protection switch is located
in the switch cabinet.
MTP – Motor protection switch for pump
If the motor current increases beyond the set value or if there is a short circuit, the motor protection
switch turns off and interrupts the current supply. The motor protection switch has to be turned on
manually after the cause of the malfunction has been eliminated.
The motor protection switch is located in the switch cabinet.
ROO – Remote control
The chiller can be switched off by the consumer or from a control room with the aid of an external con-
tact. When this occurs, the main switch remains permanently switched on.
QE – Switch cabinet
The switch cabinet contains all the electrical components and safety devices.
TLT – Temperature controller
Temperature control and regulation is carried out by the temperature controller of the chiller in accor-
dance with the preset value.
The temperature controller with digital display is integrated in the door of the switch cabinet. Fault mes-
sages are displayed on the temperature controller by means of codes.
OPTIONS – ELECTRIC CIRCUIT
Connecting cable with CEE plug
A ready-to-use mains cable is supplied with 6m oilflex cable and CEE plug 4-pole (3P+PEN) or 5-pole
(3P+N+PE).
