2. Tindakan Pencegahan Keamanan

2.1 Keamanan Listrik

Before connecting the power cord, verify that the supply voltage is AC 220 V ± 10% and the frequency is 50 Hz or 60 Hz;

You must use a three-prong outlet with a protective ground, with a protective ground resistance of ≤4 Ω. Under no circumstances should you cut or disconnect the protective ground wire, as doing so poses a risk of electric shock.

2.2 Keselamatan Lingkungan

Do not use in environments with flammable or explosive substances, strong electromagnetic interference, high temperatures and humidity, or excessive dust levels;

Operating Environment: Temperature 5°C to 35°C, relative humidity ≤ 65% RH.

2.3 Prosedur Operasional

Improper operation can easily result in personal injury, equipment damage, and distorted test data; operators must thoroughly read this manual and strictly follow the procedures;

Remove jewelry before performing the procedure, tie back long hair, and do not wear loose-fitting clothing;

During the test, take precautions to prevent test specimen fragments from flying and causing injury;

During the test, do not extend your hands or tools into the fixture’s travel range to prevent crush injuries or accidents;

Operators must not leave their posts without authorization while the equipment is in operation; in the event of an abnormality, immediately shut off the power supply;

Do not perform tests that exceed the load capacity or stroke limit, and do not use damaged or non-standard fixtures.

5. Prosedur Uji Kompresi

5.1 Sample Preparation and Placement

Select a specimen of an electrical enclosure that is free of initial cracks, plastic deformation, and in perfect condition. Based on the specimen dimensions and in accordance with Section 4.1, use the up/down keys to adjust the platen to a position slightly higher than the specimen’s height, and place the specimen in the specimen mounting position as described in Chapter 3.

5.2 Pengaturan Parameter Uji

Set the compression force and duration in accordance with Section 4.3 and the relevant provisions of the standards.

Clause 15.3 of GB/T 17466.1-2019 (IEC 60670-1:2021 Clause 15.2) requires a force of 500 N applied for 1 minute; GB/T 17466.1-2019, Clause 15.5 (IEC 60670-1:2021, Clause 15.5) requires a force of 50 N/cm² (not exceeding 1000 N) to be applied through 9 mm thick plywood, with a duration of 1 minute.

5.3 Starting the Compression Test

Jumlah	Note
①	Click the “Start Test” button to begin the test
②	Move the press block slowly toward the specimen and apply pressure.
③	When the actual pressure reaches the set value, the timer starts.
④	Once the force application time reaches the set duration, the test stops automatically and the load block returns to its original position.

Note: If the actual pressure does not reach the set value, or if the specimen breaks during the compression process, you may click “Stop Test” to manually terminate the test.

5.4 Interpretasi Hasil Tes

After the test is completed, the mounting box and housing must not exhibit any deformation or damage that would affect continued use; if this is the case, the test is considered passed.

6. Pemeliharaan dan Perawatan Peralatan Harian

6.1 Perawatan Rutin

After each test, clean up any dust or debris from the specimen mounting area to keep the work surface clean and free of debris; wipe down the equipment surface to keep it clean; verify that the clamping block is secure and that the limit stops are not misaligned; apply specialized lubricant to the drive screw to ensure smooth operation.

6.2 Spesifikasi Penyimpanan

6.2.1 Persyaratan Lingkungan Penyimpanan

Suhu: 5°C hingga 35°C; kelembapan relatif: ≤65% RH; lingkungan kering, bebas debu, dan bebas dari gas korosif.

6.2.2 Operasi Penyimpanan Jangka Panjang

Matikan daya dan cabut semua kabel; bersihkan peralatan dan bungkus dengan plastik anti debu; hidupkan daya selama 30 menit setiap bulan untuk mencegah kerusakan akibat kelembapan pada komponen.

6.3 Persyaratan Interval Kalibrasi

To ensure the measurement accuracy and operational reliability of the equipment, it is recommended that it be sent periodically to a qualified third-party metrology laboratory for calibration. The recommended calibration interval is 12 months. The specific calibration interval may be determined by the user based on frequency of use, environmental conditions, and quality system requirements.
