Installing NERO-DRY

This module is used for switching on or off the electrical device (e.g. light or fan). The module can be controlled either through a NEXUS-NERO Communications Gateway or through a wall switch.

The NERO-DRY module supports connection of a digital temperature sensor.

It is designed to act as repeater in order to improve range and stability of 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

Module supports momentary switches (push button) and toggle switches. The module is factory set to operate with toggle switches.

1.2 Protection when used with a Different Load Power Supply (DLPS)

The internal relay connected to the OUT and IN terminals of the NERO-DRY is electrically isolated from the rest of the device. Therefore, when using it as a dry contact, the protection fuse must be placed on the supply (output) wire to the load as illustrated in the wiring diagram. It must be protected by an over current protection fuse not rated any higher than 10A.

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.
