Overview
The document provides technical specifications, dimensions, and installation guidelines for the MV3QRA/MV3QRB Series solenoid valves, including details on connectors, fittings, and vacuum filters, as well as safety precautions and maintenance recommendations.

Specifications
The MV3QRA/MV3QRB Series features various connectors (C type and D type), push-in fittings (φ4 and φ6), and vacuum filters (VSFJ-44 and VSFJ-66). Lead wires are specified as AWG#26 with lengths ranging from 300 to 2000 mm. Torque requirements for mounting screws and dimensions for different models are outlined.

Procedures
Instructions for wiring connectors and crimping terminals are provided, emphasizing correct polarity and appropriate tools for crimping. A step-by-step guide for inserting terminals and sockets into the solenoid valve connector section is included.

Safety and Maintenance
The document highlights the importance of using the product within specified pressure and temperature ranges to avoid damage. It advises against using the product in corrosive or explosive environments and stresses the need for regular maintenance of vacuum filters to prevent performance issues. Recommendations for manifold operation and precautions for handling lead wires and solenoid valves are also included.

Design and Installation
Guidelines for mounting, installation, and adjustment are provided, including recommended torque values for tightening connections. The document advises on the use of stable DC power supplies and warns against exceeding specified voltage levels to prevent damage.

Warnings and Cautions
The document includes several warnings and cautions regarding the use of the product, such as the risk of electric shock, the need for proper grounding, and the potential for performance deterioration due to long energizing times.

Specifications and Procedures
Handling and Wiring: Ensure no excessive force is applied to the sensor head's lead wire to prevent damage. Turn off power before wiring and discharge static electricity. Use bending-resistant materials for movable sections.
Connection: Install a surge voltage absorption circuit when connecting to output or power supply terminals. Avoid exceeding rated current and short-circuiting output terminals.
Removal and Mounting: Use a narrow-tipped tool to remove fixing pins and pressure sensor assembly. Ensure no debris on the O-ring before reassembly.

Product-Specific Cautions
Load Short Circuit: Avoid short-circuiting the load to prevent rupture or burning.
Incorrect Wiring: Ensure correct wiring to avoid damage.
Connecting Load: Check output error with the impedance of the connecting load.

Installation and Safety
Noise and Surge Protection: Install away from noise sources and provide surge protection.
Handling: Avoid disassembling the product and ensure proper installation to prevent damage.
Protection Level: The product is IP40 rated; avoid exposure to water or oil.

Manifold Specifications
Model and Configuration: Specify manifold model numbers and configurations accurately. Mixing specifications is not allowed.
Documentation: Complete manifold specification sheets from the left end with piping ports facing rear.

Key Components
Valves and Sensors: Various models of valves and sensor-equipped valves are listed with specific model numbers.
Masking Plates: Use masking plates as specified in the documentation.
