voltages. This could result in serious bodily

injury or damage to property if not handled

properly:

• Before establishing electrical connections

to the device, earth it at the ground wire

connection if there is one.

• Hazardous voltages may arise in all circuit

parts that are connected to the power supply.

• Even after disconnecting the power supply,

there may still be hazardous supply voltages

present in the device (capacitor storage).

• Do not operate equipment with current

transformer circuits when open.

• Do not exceed the threshold values stipulated

in the operating manual - even during testing

or commissioning.

• Observe the safety and warning information in

the documents that belong to the devices!

CAUTION!

Damage to property due to

disregard of the connection

conditions or impermissible

overvoltage

Your device can be damaged or destroyed

by a failure to comply with the connection

conditions or by exceeding the permissible

voltage range.

Before connecting the device to the supply

voltage, please check:

• Voltage and frequency correspond to the

details on the ratings plate! Threshold

value stipulated in the operating manual

have been complied with!

• In building installations, the supply voltage

must be protected with a UL approved

circuit breaker / a fuse (6 A, char. B)!

• The isolation device

- must be installed near the device and

in a location that is easily accessible

for the user.

- must be labelled to identify the

respective device.

• Provide a fuse for the neutral conductor

if the neutral conductor terminal of the

source is not grounded.

The supply voltage for the device is

implemented via a 2-pole plug-in terminal.

The supply voltage level and frequency for your

WARNING!

Danger of injury due to

electrical voltage!

Serious bodily injury or death can result from:

• Contact with bare or stripped live wires.

• Device inputs that are dangerous to touch.

Render your device free of voltage before

starting work! Check the system is free of

Ethernet connection

with the PC/switch



NOTE!

The Energy Logger D550 is factory-set

to the ﬁ xed IP address 10.10.10.200

(subnet mask 255.0.0.0, DHCP =

deactivated).

The dynamic IP address is conﬁ gured

via a direct Ethernet connection with the

software (see step 14, 15 and 16).

Within an Ethernet network, each device has

a unique TCP/IP address that can be set

manually or assigned by a DHCP server.

Fixed IP address

In networks without a DHCP server, the network

address of the device must be set via Modbus

or the software.

BootP

• Allows for the automatic integration of the

device in an existing network.

• Does not have the scope of functions of DHCP.

DHCP mode

DHCP integrates the Energy Logger D550

in an existing network with DHCP server

automatically. When started, the device pulls the

IP address, the network mask and the gateway

from the DHCP server.

Direct PC connection of the Energy Logger D550 via Ethernet (Windows 7)

A common way in which to integrate the Energy

Logger D550 in your PC network is direct

connection via the Ethernet interface.

RS485 interface

The RS485 interface on the device

• is designed as a 2-pole plug contact.

• communicates via Modbus RTU protocol.

The user-friendly conﬁ guration of the device is

possible with the "ecoExplorer go" software.

RS485 bus structure

• In an RS485 bus structure (line), you connect

all devices in accordance with the Master-

Slave principle.

• One segment of an RS485 bus structure can

include up to 32 subscribers/devices.

• The cable is terminated with termination

resistors (120 Ω, 0.25 W) at the beginning and

end of a bus structure. The device contains

a termination resistor, which can be activated

via DIP switch S1.

• With more than 32 subscribers, repeaters

(ampliﬁ ers) are used to connect bus segments.

• Voltage must be present at devices with an

active termination resistor.

• Recommendation: Install the Master at the end

of a bus segment.

• If the Master device is replaced with

a termination resistor that is active, the bus

structure is out of operation.

• Replacing a Slave device with a bus

connection that is either switched on or de-

energised can destabilise the bus structure.

• Devices without a bus connection can be

replaced without this having an effect on the

bus structure.

Digital inputs

The device has 15 digital inputs.

The digital inputs are divided into 3 groups, each

with 5 inputs:

• 5 inputs share one joint earth respectively.

• LEDs indicate the status of the inputs. If the

LED lights up (green) then a signal is present

at this input.

• An input signal is present (signal "1")

if a voltage of at least 18 V is ﬂ owing

at a digital input (typically 4 mA at 24 V).

• If the input voltage is <5 V DC, no input signal

is present (signal "0").



NOTE!

For fault-free operation of the device:

• Lay screened cable from a cable

length from 30 m.

• Correct polarity of the supply

voltage for the digital inputs

(20 - 30 V DC) must be ensured.

• Digital output 1 can be conﬁ gured to monitor the

temperature. It is connected with a comparator

via the thermistor input.

The digital outputs:

• can be switched via Modbus and the weekly

switch clock.

• can display the results of comparators.

• require external auxiliary voltage.

• can be used as pulse outputs.

• switch AC and DC loads.

• are not short circuit-proof.
