Terminal Block ALLNET ALL1688PC

The ALLNET ALL1688PC terminal block is a phase coupler designed for DIN-rail installation in the fuse box. It combines all phases of a home power network so that Powerline signals are available at the electrical sockets within the same circuit. The device also supports implementation of a fourth LX-phase cross-connection to other circuits to overcome obstacles for powerline communications such as electricity meters, earth leakage devices (GFCI), circuit breakers and similar installations.

Advantages

The ALLNET ALL1688PC provides a compact, robust solution for phase coupling on DIN rails, offering multiple connection points for straightforward wiring and organized circuits. It enables reliable transmission of Powerline signals across phases and helps maintain communication in installations where standard line topology would interrupt the signal. Its construction suits long-term operation within typical electrical distribution panels.

Suitable for

• Residential and small commercial electrical distribution boards
• Powerline communication setups requiring phase coupling
• Installations with meters, GFCI or breakers that block PL signals
• DIN-rail mounting inside fuse boxes or consumer units

Key specifications

• Brand: ALLNET
• Model / MPN: ALL1688PC
• EAN: 4038816016881
• Mounting: DIN-rail (fuse box / consumer unit)
• Function: Phase coupler for Powerline networks; supports LX-phase cross-connection

How to use

Install the ALLNET ALL1688PC on the DIN rail inside the fuse box and make the phase and neutral connections according to the electrical schematic of the installation. Use the provided connection points to join the phases you need coupled; where required, implement the fourth LX-phase cross-connection to other circuits to route Powerline signals past meters, GFCIs or breakers. Ensure all connections are tightened and secured, and follow local electrical codes for wiring and isolation. Commission the Powerline devices after the coupler is in place to verify signal availability at sockets.

Recommendations

Only qualified personnel should install and configure the terminal block. Verify compatibility with existing Powerline devices and perform testing after installation. Follow local regulations and the electrical panel manufacturer’s guidance when altering phase connections.
