and have been instructed in the use of the Ex p power relay;
have read and understood the documentation, the chapter on safety and
the warnings.
The owner must check that the safety regulations and accident prevention
rules valid for the respective application are observed.
Instructions for use
The control unit must be completely installed in an enclosure that meets
the requirements for the enclosure according to IEC 60079-0 with a
minimum degree of protection of IP 54 for EPL Gb and IP 6X for EPL Db.
The overvoltage category II of the non-intrinsically safe circuits according
to IEC 60664-1 must be observed.
The warning “WARNING – DO NOT OPEN UNDER VOLTAGE” must be part of
the external marking of the entire electrical device or the enclosure must
have a locking system to prevent the fuses from being energised during

Avoidance of damage to property
Short circuit due to improper connection
An incorrect connection of the power supply will destroy the electronics and void
the warranty.
Storage at an excessively high temperature
Store the Ex p control unit at the intended storage temperature since otherwise
damage to the electronics or seals may occur. Ensure adequate air conditioning
at high storage temperatures.
Aggressive cleaning agents
When selecting the correct cleaning agent, it is essential that it is suitable for
use since otherwise damage may occur to seals and connections. Combustible
products are generally not permitted.
Danger to health due to improper disposal
According to the European WEEE Directive, electrical and electronic equipment
may not be disposed of with household waste. Their components must be sent
separately for recycling or disposal because toxic and hazardous components
can cause long-term damage to health and the environment if not disposed of
properly.
As consumers, you are obliged under the Electrical and Electronic Equipment Act
(ElektroG) to return electrical and electronic equipment at the end of its
serviceable life free of charge to the manufacturer, the point of sale or to public
collection points set up for this purpose. Details of this are regulated by the
respective national law. The symbol on the product, the operating instructions
or/and the packaging refers to these regulations. With this type of material
separation, recycling and disposal of old devices, you make an important
contribution to the protection of our environment.

3Product description
General information
The Ex p power relay is intended for the safe separation of supply lines directly in
hazardous areas and can be used together with the BARTEC pressurised
enclosure systems APEX or SILAS.
The Ex p power relay has four electrically isolated switch contacts which open
the contacts when the power falls away. The safe opening of the contacts is
guaranteed by two series-connected relays. Up to three phases of supply lines
can be switched off using the switching power of 400V, 16 A and 4kW.
The Ex p power relay is available in three different activation voltages and as a
module for integration in a separately certified enclosure or as a complete
control unit.
Ex p power relay
Module
The Ex p power relay (module) must be installed in an enclosure with the
minimum dimensions of 220 mm x 120 mm x 90 mm.
The enclosure must be certified according to a recognised ignition protection
class in accordance with section 1 of IEC/EN 60079-0.
In the case of installation in an enclosure with enhanced safety “e“ IEC/EN
60079-7, the clearances and creepage distances and ambient temperatures
must be observed.
If used in atmospheres with high air humidity, a separately approved
enclosure with breathing device must be used.
Complete control unit
The Ex p power relay (complete control unit) is installed in an enclosure in
accordance with IEC/EN 60079-7 with the dimensions 220 mm x 120 mm x 90
mm.
It can be simply mounted to the Ex p protected equipment using the
installation aids on the enclosure.
