8.2 DC Switch Check

In normal use, the DC switch requires no maintenance.
Although not strictly necessary, we still recommend you to:
• check the DC switch regularly:
• turn the DC switch on and off 10 times a year.
Operating the switch regularly can clean up the device and extend its service life.

Note: 

Turn off the AC breaker first, and then turn off the DC switch.

8 Product Maintenance

Regular maintenance of the inverter will ensure its service life and best efficiency.
Note: Before carrying out any maintenance, turn off the AC circuit breaker, disconnect the DC 
circuit breaker, and wait 5 minutes until the residual voltage is released.

8.1 Clean Fan

The external fan of the HT series inverter needs to be cleaned with a vacuum cleaner every 
year. Remove the fan and give it a thorough clean.
1. Turn off the AC circuit breaker first, and then turn off the DC switch;
2. Wait 5 minutes until the residual voltage is released and the fan stops running;
3. Remove the fan net;

Use a screwdriver to loosen the fan bracket
Carefully disassemble the fan net and fan (because the internal circuit of the fan is still 
connected, do not pull out a single fan) as shown in the diagram below;

4. Use a soft brush, cloth or compressed air for cleaning; tighten the screws.
