The power module MACX MCR-PTB(-SP) enables the
supply voltage on the foot elements (DIN rail connectors) to
be provided on either a redundant or a non-redundant basis.
The module MACX MCR-PTB(-SP) has integrated error
evaluation. An auxiliary supply failure or fuse error is
registered to a relay contact and displayed via a flashing
LED.
With MACX MCR-EX-SL-(2)NAM... devices connected via
DIN rail connectors, a collection line fault is signaled.
The devices can be installed in zone 2 with the "n"
(EN 60079-15) protection type.
WARNING: Explosion hazard
The device is an associated item of electrical equipment for intrinsically safe circuits. It is designed for
use in zone 2, if specific conditions are observed.
When installing and operating the device, the applicable safety directives (including national safety directives),
accident prevention regulations, as well as general technical regulations, must be observed.
WARNING: Explosion hazard
Be sure to observe the safety regulations and installation notes on page 4.
Make sure you always use the latest documentation.

Installation and operation
4.2
Safety regulations for installation in the
potentially explosive area
Follow the installation instructions.
NOTE:
Installation, operation, and maintenance
may only be carried out by qualified specialist
personnel.
When installing and operating the device, the applicable
safety directives (including national safety directives),
accident prevention regulations, as well as general
technical regulations must be observed.
NOTE:
The circuits inside the device must not be
accessed.
Do not repair the device yourself, but replace it with an
equivalent device. Repairs may only be carried out by the
manufacturer.
NOTE:
The device is designed to meet IP20
protection when:
– It is installed outside potentially explosive
areas.
– The environment is clean and dry.
Install the device in a suitable housing with a suitable degree
of protection in accordance with IEC 60529 in order to
