The  customer  may  also  need  to  purchase  the  auxiliary  drain  pan(Figure  10.4.9)  separately  from  the 
manufacturer if required. See the steps below for installation of auxiliary drain pan: 
Electrical connections 
Caution: 
  Make sure that the power supply falls with 220-240V~1ph 50Hz/60Hz and is able to provide enough wattage 
for the unit. The power supply system must comply with the current national safety regulations. 
  The electrical connection must be completed by qualified professionals and must comply with local laws and 
regulations. The company is not responsible for personal or property damage resulting from any incorrect 
electrical connections. 
  Provide dedicated and suitable leakage protection device for the unit, with a minimum distance of 3 mm 
among the wiring contacts. The unit must be grounded reliably. 
  Make sure that the power cord has a large-enough cross section to withstand the maximum current required. 
Never use a damaged cable. 
  Perform electrical connections according to the wiring nameplate of the unit. 
  Secure the cable using clamps in the electric control box to ensure the safety of the power supply cable and 
the connection cable. 
  Do not pull, step on or squeeze the cable. Do not use nails or staples to secure the power cord. 
You need to pass the cable through the knockout hole at the foundation. 
  For this stationary appliance it is required to have for disconnection of mains supply and all-pole switch with a 
contact opening of at least 3mm in the fixed wiring 
Danger! 
Always install a  general automatic switch in a  protected area near the  appliance with an adequate capacity 
characteristic  delayed  curve  with  sufficient  breaking  power.  There  should  be  a  minimum  distance  of  3mm 
between the contacts. Earth connection is compulsory by law to ensure user safety while the machine is in use. 
Refer to Tables 10.4.1&10.4.2for the specifications of the power cord and communication wire. A wiring capacity 
that is too small will cause the electrical wiring to become too hot, and lead to accidents when the unit burns and 
becomes damaged. 
Select the wire diameters ( minimum value) individually for each unit based on the Table 10.4.2. 
Maximum allowable voltage range variation between phases is 2%.
