Electric Controls; Control Panel - Daikin LMD MF075 Manuel D'installation

When choosing the protective device take the following into consideration: should the
current
at installation point be higher than 10 KA, install a limiting device which reduces its peak value to 17 KA.
Prospective short-circuit current (Ik)
provided that no protective device against overcurrent has been installed on the circuit.
Peak value:
max value of prospective short-circuit current.
ATTENTION
Connection to the electric line shall be effected applying a suitable safety device (a
circuit breaker or a ground fault interrupter) selected by the installer on the basis of the
line involved and of the absorption indicated on the unit plate.
If a cold room includes more units, each unit shall be provided with its own safety device.
We advise to install a microswitch (not supplied) on the cold room door which will
- switch on the light in the cold room, stop the unit and
- override the temperature alarm (for about one hour after door closing)
every time the door is opened.
The necessary cable is available with the unit. Connect it keeping in mind the following:
microswitch closed = door closed.
ATTENTION
Above microswitch is not supplied with the unit. If the microdoor cable is disconnected
or damaged, the same conditions will occur as in case of open door and connected
microdoor.
WARNING
Any defective electrical part should be replaced by trained personnel exclusively.
The electric connection should be effected by qualified personnel.
