Simple standard rail mounting.
Class I+II+III / Type 1+2+3 surge protection.
Application:
• The Type 1 surge protector is usually installed at the junction of LPZ0B and LPZ1
• It can be installed in the low voltage power distribution cabinet/box of building.
• It is suitable for distribution cabinets and distribution boxes with outdoor access lines in buildings.
Installation:
• Power must be cut off before installation. Live operation is prohibited.
• It is recommended that a fuse or circuit breaker be connected in series at the front end of the surge protection.
• SPD is installed in parallel at the power supply inlet end of the building distribution box or the equipment room. The product is installed in the guide rail type. If conditions permit, the Kevin connection mode can be adopted.
• During installation, connect the device according to the installation diagram, where L is the phase line,N is the neutral line, and PE is the ground line. Do not misconnect the device. After the installation is complete, turn on the automatic circuit breaker and check whether the working status is normal.
• When the SPD is in use, check the status of the fault display window regularly. If the fault display window is red or the remote terminal outputs an alarm signal, it indicates that the SPD is faulty and should be repaired or replaced in time.
• Suitable for indoor operation, such as installed in the outdoor, must be equipped with waterproof shell.
