2. Safety Precautions

2.1 Electrical Safety

2.1.1 Power Connection Specifications

Based on the nameplate, connect the test chamber to the correct input power supply: 220V/380V 50Hz (test chambers without IPX5 or IPX6 ratings require a single-phase 220V input, while those with IPX5 or IPX6 ratings require a three-phase 380V input;60 Hz is available upon request), and ensure the voltage and frequency are correct. Please use a dedicated circuit to avoid sharing the circuit with other high-power equipment. Confirm that all connections are secure and free of looseness.

2.1.2 Grounding Requirements

The test chamber must be reliably grounded, with a grounding resistance of ≤4 Ω. Do not use gas pipes, non-metallic water pipes, or the neutral wire as a substitute for the grounding wire. After grounding is complete, use the Grounding Resistance Tester to measure the ground resistance. Power may only be applied after confirming that the resistance meets the requirements, to prevent electric shock, test chamber malfunctions, or measurement errors caused by poor grounding.

2.1.3 Electrical Operation Precautions

Before wiring, inspecting, or maintaining equipment, the main power supply must be disconnected, and operations may only proceed after confirming that there is no residual voltage;

Do not operate the test chamber’s power switch, touchscreen, or instrument buttons with wet hands to avoid the risk of electric shock;

Do not place any foreign objects (such as tools or paper) inside the electrical control cabinet to prevent dust or foreign objects from causing short circuits or damaging components;

Do not plug in or unplug power cords or signal cables while the equipment is running to prevent short circuits that could damage the controller or electrical components.

2.2 Environmental Safety

Sufficient clearance must be maintained between the equipment and walls, as well as surrounding fixtures (such as other test equipment and shelving), to ensure proper operation of the equipment and to facilitate operation and maintenance;

The test chamber should be placed on a solid, level surface; its adjustable feet can be used to ensure that the test chamber remains level.

No.	Note
① Sample Power Supply	If your sample requires power during testing, please connect the appropriate power source here based on your sample’s specific requirements. Short circuits may occur during testing, so please connect an external ground-fault circuit interrupter.
② Filtration System	The filter cartridge must be replaced when it has discolored significantly. (Note: If only IPX5 and IPX6 testing is included, there is no filtration device.)
③ Air Inlet	Used to connect to an air compressor (Note: This is used solely to quickly drain water from the IPX1/IPX2 drip tray; not connecting it to an air compressor does not affect the normal operation of the Waterproof Test Chamber at any waterproof rating.)
④ Inlet	Connect the corrugated hose to a clean water source, and keep the water supply valve open at all times.
⑤ Drain opening	The valve should remain closed at all times; it should only be opened when the tank needs to be cleaned or drained.
⑥ Power cord	Refer to the product nameplate and connect the device to the correct power source.

Figure 7

Note 1: Before using the unit for the first time, inspect the test chamber, water tank, and all water lines, remove any debris, and clean them with clean water.

Note 2: We recommend using deionized water or purified water (a water purifier may be used). If tap water is used, the minerals and impurities it contains can easily cause scale buildup, which affects the test water flow rate. This may require frequent replacement of filter cartridges, unclogging of needles, cleaning of solenoid valves, and other maintenance, and may even damage the water pump.

3.4 Sample Connection and Installation

No.	Note
①	If the sample requires testing under power, use the standard waterproof plug and socket for connection.
②	The test specimen must be secured to the center of the turntable using straps (Note: For IPX1 and IPX2 testing, the axis of the test specimen must be 100 mm from the axis of the turntable). If the test specimen has any protruding parts, ensure that it will not collide with the equipment while the turntable is rotating to prevent damage to both the equipment and the test specimen.
