Pytes Negative Cable, 2 m – Amphenol 5.7 mm to M8

The Pytes connection cable with the manufacturer's part number 161412100245 Connects a negative Amphenol 5.7-mm connector to an M8 screw terminal. The 2-meter-long black DC cable is pre-assembled with an Amphenol plug and an M8 ring terminal.

When connecting a Victron Multi RS19 Connect the black Amphenol connector to the inverter's negative battery terminal. The M8 ring terminal leads to the battery, battery fuse, busbar, or DC distribution panel with a matching M8 connection.

Advantages of the pre-assembled negative cable

• Compatible with the Victron Multi RS19: Amphenol 5.7-mm connector for the device's negative battery terminal.
• M8 ring terminal: For a suitable battery, fuse, busbar, or DC distribution connection.
• 2 m cable length: Provides flexibility for clear cable routing within the power system.
• Unambiguous polarity: The black color identifies the cable as the negative DC wire.
• Pre-assembled: The Amphenol connector and M8 ring terminal are already installed.

Connection to the Victron Multi RS19

The Victron Multi RS19 features Amphenol SurLok Plus connectors for connecting to the battery. The The black 5.7-mm Amphenol plug on this cable connects to the negative battery terminal of the Multi RS19 used.

The M8 ring terminal at the other end of the cable is connected to the negative M8 terminal of the designated battery or to an intermediate DC fuse or busbar. Together with the corresponding orange positive wire, this forms a pre-assembled cable pair for connecting the Multi RS19 to the battery.

Compatibility with Pytes E-BOX

The connection cable is designed for DC system configurations with the Pytes E-BOX 48100R and the Pytes E-BOX 4850 Suitable, provided there is a matching negative M8 connection point on the designated connection side.

Since Pytes batteries may use different power connectors depending on the model, revision, and installation type, the specific connector type must be verified before placing an order. For a battery model with an Amphenol connector, a suitable Amphenol-to-Amphenol connector is required for a direct connection to the Multi RS19, which is also equipped with an Amphenol connector.

How to Correctly Distinguish Between Amphenol 5.7 mm and 4 AWG

The specification "5.7 mm" refers to the size of the Amphenol connector. It does not describe the conductor cross-sectional area. The cable itself is supplied by Pytes as UL10269, 4 AWG specified. 4 AWG corresponds to approximately 21.15 mm² (nominal).

This cable should not be confused with Pytes cables for Amphenol 8.0 mm or with versions designed for M10 mounting studs. When selecting a cable, always consider both cable connectors and the required polarity.

Technical Specifications

Applications

The negative cable is suitable for 48-V battery systems in which a negative 5.7-mm Amphenol connector must be connected to an M8 connection point. These include appropriately configured stationary solar storage systems, off-grid systems, emergency power systems, and grid-connected ESS systems.

What matters is not just the product names of the connected components, but the actual connection configuration and the proper electrical design of the entire system.

Installation Instructions

Installation may only be performed when the system is de-energized and protected against accidental re-energization. Before connecting, the positive and negative terminals must be clearly identified and checked with a suitable measuring device.

Fuse protection, maximum system current, the number of batteries in parallel, wiring, and connection torque must be determined based on the current documentation from Victron, Pytes, and the other components used. Work on battery storage systems must be performed by appropriately qualified professionals.

Conclusion

The Pytes Minus Cable 161412100245 features a pre-assembled Amphenol 2-meter connector, 5.7 mm to M8. With the Victron Multi RS19, the black Amphenol connector is plugged into the inverter, while the M8 ring terminal leads to the battery or DC distribution panel. The black marking ensures clear identification as the negative DC wire.

Frequently Asked Questions About the Pytes Minus Cable 161412100245

• How do you connect the cable to the Victron Multi RS19?

  
  

  The The black 5.7-mm Amphenol plug connects to the negative battery terminal of the Multi RS19 Connected. The M8 ring terminal leads to the battery, DC fuse, busbar, or distribution panel with a matching M8 connector.

• Is this cable compatible with the Pytes E-BOX 48100R and E-BOX 4850?

  
  

  This cable is suitable for system configurations with the Pytes E-BOX 48100R and E-BOX 4850, provided the intended connection point has a compatible M8 connector. Since there are different battery and connector versions, the specific model must be verified before placing an order.

• Are the positive and negative cables included?

  
  

  No. The package includes a single black negative cable. The corresponding orange Plus cable must be ordered separately.

• Does the cable have a cross-sectional area of 5.7 mm²?

  
  

  No. The 5.7 mm specification refers to the Amphenol connector. The cable is 4 AWG specified, which corresponds to approximately 21.15 mm² in nominal terms.

• Does this cable also fit Amphenol 8.0-mm or M10 connectors?

  
  

  No. This cable has a 5.7-mm Amphenol connector and an M8 ring terminal. Different cable versions are required for 8.0-mm Amphenol or M10 connectors.

• What is the maximum current that can flow through the cable?

  
  

  The permissible current depends on the entire system, the installation method, the ambient temperature, the connections, and the fuse protection. The current manufacturer’s documentation and the proper sizing of the system are decisive factors.
