pany and/or CIRCUTOR's after-sales service.

2  PRODUCT DESCRIPTION

The CBS-2000AB is a hybrid earth leakage current monitoring device that can be used to connect up

to 16 type-A channels via transformers in the WGC range, and 4 type-B channels using transformers

in the WGB range.

The CBS-1600A model is a type A earth leakage current monitoring device with up to 16 measurement

channels using transformers in the WGC range.

The device features:

-Display for viewing the parameters.

- 3 keys to browse through the different screens and program the device.

-2 relays: an alarm relay and a pre-alarm relay.

- Digital input for external trip.

- RS-485 communications.

The WGB are a range of electronic, type-B earth leakage protection and monitoring transformers (IEC

60755).

Circutor has 4 models, depending on the maximum current of the monitored circuit (In):

WGB-35, for In: 80 A.

WGB-55 for In: 160 A.

CBS-2000AB, CBS-1600A

Instruction Manual

WGB-80 for In: 250 A.

WGB-110 forIn: 400 A.

The transformers have:

- 6 LEDs providing information about the transformer's status.

- 2 RJ45 connection and power supply ports.

The WGC is a range of electronic, type A earth leakage protection and monitoring transformers (IEC

60044-1).

CIRCUTOR offers 14 models, depending on the size of the transformer.

3. INSTALLATION OF THE DEVICE

3.1.- PRELIMINARY RECOMMENDATIONS

In order to use the device safely, personnel operating it must follow the safety meas-

ures that comply with the standards of the country where it is to be installed; operators

must wear the required personal protective equipment (rubber gloves, approved facial

protection and flame-resistant clothing) to prevent injuries from electric shock or arcs

caused by exposure to current-carrying conductors, and they must heed the various

warnings indicated in this instruction manual.

The CBS-2000AB/CBS-1600A device must be installed by authorised and qualified staff.

The power supply plug must be disconnected and measurement systems switched off before handling,

altering the connections or replacing the device. It is dangerous to handle the device while it is pow-

ered.

Cables must always be kept in perfect condition to avoid accidents or injury to personnel or installa-

tions.

Restrict the operation of the device to the specified measurement category, voltage or current values.

The manufacturer of the device is not responsible for any damage resulting from failure by the user

or installer to heed the warnings and/or recommendations set out in this manual, nor for damage

resulting from the use of non-original products or accessories or those made by other manufacturers.

Do not use the device to take any measurements if an anomaly or malfunction is detected.

Check the surrounding environment before starting to take measurements. Do not take any measure-

ments in hazardous or explosive environments.

Before carrying out maintenance, repair or handling of any of the device's connections,

the device must be disconnected from all power sources, both from the device's own

power supply and the measurement's.

Contact the after-sales service if you detect that the device is not working properly.

Instruction Manual

3.2.- INSTALLATION

When the device is on, its terminals, opening covers or removing elements may ex-

pose the user to parts that are hazardous to touch. Do not use the device until it is

fully installed.

The device must be installed inside a medium or low voltage electric panel or enclosure, with DIN rail

mounting (IEC 60715).

The device has a LED (CPU) that indicates voltage presence. Even in the case that the

aforesaid LED is off, the user still needs to check the device is disconnected from any

power supply.

The device must be connected to a power circuit protected by a fuse according to its power and con-

sumption rating. It must be fitted with a circuit breaker or equivalent device to disconnect the device

from the power supply.
