SM TRIO52 1- E.1 GB

1.6  Precaution, Advise and Notice Items

1.6.1  High voltage in Outdoor unit controller.  

Whole controller, including the wires, connected to the Outdoor unit controller may have the potential hazard 
voltage when power is on. Touching the Outdoor unit controller may cause an electrical shock. 
Advise: Don’t touch the naked lead wire and don’t insert finger, conductor or anything else into the controller 
when power is on. 

1.6.2 Charged 

Capacitors 

Three large-capacity electrolytic capacitors are used in the Outdoor unit controller. Therefore, charging 
voltage (380VDC) remains after power down. Discharging takes about three minutes after turned off. 
Touching the Outdoor unit controller before discharging may cause an electrical shock. When open the 
Outdoor unit controller cover, don’t touch the soldering pin by hand or by any conductive material.  

Advise: 

                  1. Open the Outdoor unit controller cover only after five minutes from power down. 

2. Measure the electrolytic capacitors voltage before farther checking controller for safety.  

1.6.3 Additional 

advises 

 

When disassemble the controller or the front panel, turn off the power supply.  

 

When connecting or disconnecting the connectors on the PCB, hold the whole housing, don’t pull the   

               wire.   

 

There are sharp fringes and sting on shell. Use gloves when disassemble the A/C units.
