This module is used for switching on or off two electrical devices.  The module can be controlled either through a NEXUS-NERO Communications Gateway or through a wall switches.

The NERO-2RELAY module measures power consumption of two electrical devices and supports connection of a digital temperature sensor.

It is designed to act as repeater in order to improve range and stability of the Z-Wave Network.

 

1. INSTALLATION

 

• Before the installation, disconnect the power supply

• Connect the module according to electrical diagram

• Locate the antenna as far as possible from metal elements

• Do not shorten the antenna

 

1.1 Supported Switches

NERO-2RELAY supports momentary switches (push button) and toggle switches. The module is factory set to operate with toggle switches.

​

1.2 Overcurrent Protection Fuse

NERO-2RELAY must be protected by an over current protection fuse not rated any higher than 4A as illustrated in the wiring diagram.

 

Danger of electrocution!

• Module installation requires a great degree of skill and may be performed only by a qualified and licensed electrician.

• Even when the module is turned off, voltage may be present on its terminals. Any works on configuration changes related to connection mode or load must always be performed with a disconnected power supply.

 

Note: Do not connect the module to loads exceeding recommended values. Connect the module only in accordance to the below diagram. Improper connections may be dangerous.
