2. Product Overview
2.1. Product Description
Grid management of PV plants with TLX Pro or TLX Pro+ inverters is handled by the CLX GM
and the master functionality of the TLX Pro and TLX Pro+ inverters.
The CLX GM is connected directly to the output of a radio ripple control receiver. The receiver
has 4 digital outputs K1-K4, which are used by the grid operators for signalling either power
reduction or reactive power setpoint commands.
The CLX GM reads the current relay state and via its Ethernet connection to the inverter net-
work it broadcasts a message to the master inverter. Therefore all configuration of how to react
upon a certain relay state is performed directly in the master inverter itself. The CLX GM is con-
nected to the receiver and the inverter network and requires no additional configuration.

2.2. System Requirements
2.2.1. Intended Use
The CLX GM is intended solely for use with TLX Pro and TLX Pro+ inverters.
Drilling holes in the equipment or mechanical modifications will damage the equip-
ment and invalidate the warranty.

2.2.2. System Requirements
The CLX GM has a built-in web interface, for display of simple status information and configura-
tion.
The following web browsers are recommended:
Internet Explorer® Version 6 or later
Firefox® Version 2 or later
Note:
The grid management behaviour is configured directly via the web interface of the TLX Pro
or TLX Pro+ master inverter. For configuration, a PC and a crossed network cable are there-
fore needed and must be available at commissioning.

4. Installation
4.1. Installation
The CLX GM is connected to the master inverter of the inverter network via LAN interface, con-
sisting of an Ethernet network between the inverters and the CLX GM. Use a standard patch
cable (network cable cat5e or better with RJ-45 connectors).
Note:
On all units, remember to use the Ethernet (LAN) RJ-45 connectors and not the RS-485 in-
terface.
The CLX GM and the inverters can work in networks with or without a DHCP server (router),
supporting both static and dynamic IP addressing.
Configuration of the CLX GM depending on whether there is a DHCP server (router) in the net-
work or not.
Refer to Chapter 5,
Configuration
, for further information on how to proceed.
4.2. Mounting
The CLX GM must be installed indoors or in an electrical enclosure. It can be mounted either
horizontally or vertically (connectors facing downwards) on a mounting rail system or on a wall
using the supplied wall bracket.
Illustration 4.1: Wall Bracket
Fit the CLX GM to the bracket by clipping the screws on the back of the unit into the bracket.
When mounting the equipment, ensure free access for cable connections from below. Use cable
anchors for strain relief.
4. Installation

Like all electronic equipment, all products in the CLX GM must be protected from
humidity, in particular condensation.
4.3. Signalling of Grid Management
Signalling of grid management is handled by the ripple control receiver of the DNO. The con-
nection between the ripple control receiver and the CLX GM is type-dependent. It is described
here using a Landis+Gyr® receiver as an example.
Illustration 4.2: Grid Management - Connections
The ripple control receiver is connected as follows:
Input Terminal Strip Function Ripple Control Receiver Connector (K)
+S 12-30 VDC K1
-S1 Relay input 1
+S 12-30 VDC K2
-S2 Relay input 2
+S 12-30 VDC K3
-S3 Relay input 3
+S 12-30 VDC K4
-S4 Relay input 4
A2- N/A (0)4 .. 20 mA
A2+ N/A
A1- N/A (0)4 .. 20 mA
A1+ N/A
Note:
Detailed configuration of grid management is done via the grid management menu of the
master inverter.
To avoid damage to the CLX GM unit and the ripple control receiver, only an au-
thorised and suitably trained electrician must set up the connection.
