2 Important Notes

This section includes an overall summary of the most important safety

requirements and notes that are mentioned in each individual section. To protect

your health and prevent damage to devices as well, it is imperative to read and

carefully follow the safety guidelines.

2.1 Legal Bases

2.1.1 Subject to Changes

WAGO Kontakttechnik GmbH & Co. KG reserves the right to provide for any

alterations or modifications. WAGO Kontakttechnik GmbH & Co. KG owns all

rights arising from the granting of patents or from the legal protection of utility

patents. Third-party products are always mentioned without any reference to

patent rights. Thus, the existence of such rights cannot be excluded.

2.1.2 Personnel Qualifications

All sequences implemented on 787 Series devices may only be carried out by

electrical specialists with sufficient knowledge in automation. The specialists must

be familiar with the current norms and guidelines for the devices and automated

environments.

2.1.3 Use of the 787 Series in Compliance with Underlying

Provisions

The 787 Series power supply system provides DC voltage to electric or electronic

devices, such as industrial control systems or display, communication and

measuring devices.

The devices have been developed for use in an environment that meets the IP20

protection class criteria. Protection against finger injury and solid impurities up to

12.5 mm diameter is assured; protection against water damage is not ensured.

Unless otherwise specified, operation of the components in wet or dusty

environments is prohibited.

The devices are designed for installation in an enclosure. Under no

circumstances may they be used in control systems for planes or in nuclear

facilities, as any malfunction in these applications could result in severe injuries

or risk of death.

2.2 Safety Advice (Precautions)

For installing and operating purposes of the relevant device to your system the

following safety precautions shall be observed:

Do not work on devices while energized!

All power sources to the device shall be switched off prior to performing any

installation, repair or maintenance work.

Installation only in appropriate housings, cabinets or in electrical operation

rooms!

Always install devices of the 787 Series in enclosures, cabinets or electrical

equipment rooms which can be closed and locked. Ensure that access to this

equipment/these rooms is possible only by authorized specialists with the

appropriate key or tools.

Do not use these devices in control systems for planes, trains or nuclear

facilities!

Never use these devices in control systems for planes, trains or nuclear facilities,

as any malfunction in these applications can result in severe injuries or risk of

death!

Ensure a standard connection!

To minimize any hazardous situations resulting in personal injury or to avoid

failures in your system, the data and power supply lines shall be installed

according to standards, with careful attention given to ensuring the correct

terminal assignment. Always adhere to the EMC directives applicable to your

application.

Switch off power supply to defective device!

Switch off power supply to the device immediately if the device malfunctions or is

damaged! Control systems connected to the device may also be damaged!

Return the defective device directly to WAGO.

787-1668/0000-0080 Electronic Circuit Breaker

Manual

Version 1.1.0, valid from firmware 2.4.0

Do not plug in or disconnect the female connector while a load is applied!

Only plug in or disconnect the female connectors when the device is not live!

Failure to observe this can result in damage to the contacts due to arcing!

Plug the female connectors all the way into the male connectors!

Always plug the female connectors all the way in to the male connectors. This

ensures proper contact at all times.

Attach the free ends of the conductors using a strain relief device!

Female connectors can be pulled out of the male connectors by high vibration

levels or shock impacts!

Provide appropriate strain relief means to attach and cap any free ends of the

conductors!

Protect the components against materials having seeping and insulating

properties!

The components are not resistant to materials having seeping and insulating

properties such as: aerosols, silicones and triglycerides (found in some hand

creams). If you cannot exclude that such materials will appear in the component

environment, then install the components in an enclosure being resistant to the

above-mentioned materials. Clean tools and materials are imperative for

handling devices/modules.

Clean only with permitted materials!

Clean housing and soiled contacts with propanol.

Do not use any contact spray!

Do not use any contact spray. The spray may impair contact area functionality in

connection with contamination.

Do not reverse the polarity of connection lines!

Avoid reverse polarity of data and power supply lines, as this may damage the

devices involved.

Important Notes 13

787-1668/0000-0080 Electronic Circuit Breaker

Manual

Version 1.1.0, valid from firmware 2.4.0

Avoid electrostatic discharge!

The devices are equipped with electronic components that may be destroyed by

electrostatic discharge when touched. Please observe the safety precautions

against electrostatic discharge per DIN EN 61340-5-1/-3. When handling the

devices, please ensure that environmental factors (personnel, work space and

packaging) are properly grounded.

Version 1.1.0, valid from firmware 2.4.0

3 Device Description

The 787-1668/0000-0080 electronic circuit breaker reliably protects up to 8 load

circuits against short circuiting and overloading. The 24 VDC input voltage

applied to 8 output channels, each of which can be provided with separate fuse

protection:

Table 3: Channel Fuse Protection

Version

Fuse Protection per Channel

787-1668/0000-0080

1 A, 2 A, 3 A, 4 A, 6 A, 8 A, 10 A

The electronics can accommodate brief current peaks.

The IO-Link interface can be used to set all listed trip currents. The device also

has 8 rotary switches which can be used to set 5 different trip currents.

The actual status of the output channel is indicated by a multi-colored LED.

In the event of a short circuit or overloading, the individual channel is de-

energized after a defined trip time.

Wait for temperature to return to normal!

If a channel has been de-activated due to short-circuiting or overloading, wait

until the temperature returns to its normal range (cooling period) before re-

activating the channel.

The terms “switched ON” and “switched OFF”, as well as “tripped” are used in

this manual. To clearly delineate these terms, they are explained as follows:

Table 4: Definition of Terms

Designation

Definition

Switched ON

The user has activated the electronic circuit breaker

manually from the button or by a corresponding

interface command. The load circuit is closed, the

current flows.

Switched OFF

The user has deactivated the electronic circuit

breaker manually from the button or by a

corresponding interface command. The load circuit

is open, the current flow is interrupted.

Tripped

The electronics of the electronic circuit breaker have

been tripped due to overcurrent, undervoltage or

overvoltage. The load circuit is open, the current

flow is interrupted.
