5. START UP

This chapter provides instructions to ensure a safe start- up of the DLX inverters. The start-

up of the inverter requires the presence of AC and DC voltages. Do not attempt to start up

or commissioning the inverter if one of the voltage sources is not available.

5.1. How to Start Up

A minimum available voltage of 184 V

, 230 V

and a DC power greater than 7 W

required before the inverter starts-up and begins feeding power to the grid.

AC Side

• Turn ON the AC circuit breaker(s).

DC Side

• Turn ON the DC switch(es).

5.2. Initial Start

When the inverter is started for the first time, with minimum available voltages of 184 V

230 V

and a DC power greater than 7 W

, an installation menu is automatically

displayed to enable the configuration of certain critical values and operational settings.

5.2.1. Customizing the Inverter Settings

Single Inverter

• When both the AC circuit breaker and the DC switch are turned ON and the inverter is

supplied with enough power, the installation menu is displayed on the LCD screen.

Multiple Inverters Connected

1. CAN

• Connecting all inverters via the CAN bus enables the configuration of all inverters in a

plant via one inverter. The Start Up can then be carried out on any inverter, and if

configured as the master inverter the configuration settings of time, date, language and

grid settings will be transferred to all the other follower inverters on the network.

•

Each inverter is automatically assigned an ID number from the master during Start Up.

NOTICE

If multiple inverters are connected together, all inverters must be connected to the

CAN bus, and receiving sufficient AC and DC power, before Start Up to benefit from

single installation setup.
