Pollution level 2: Usually there is only non-conductive pollution, but there may be temporary conductive pollution caused by condensation;
Pollution level 3: There is conductive pollution, or non-conductive pollution becomes conductive pollution due to condensation;
Pollution level 4: There is persistent conductive pollution, such as pollution caused by conductive dust or rain and snow.

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.

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.

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.

Startup sequence

1. Turn the circuit breaker on the AC side to the “ON” position;
2. Turn the DC switch of the inverter to the “ON” position.

Shutdown sequence

1. Turn the circuit breaker on the AC side to the “OFF” position;
2. Turn the DC switch of the inverter to the “OFF” position.

If the startup and shutdown sequences given above are not followed strictly, the inverter may be damaged.

Electrical Connection Check

1. Check whether the cable connection is loose;
2. Check whether the grounding cable is reliably grounded;
3. Check whether the waterproof covers for RS485, WiFi and other ports are sealed correctly.

Note: The maintenance cycle is once every six months.
