2 Safety | General safety notes
2 Safety
This section includes general safety notes on handling prod-
ucts belonging to the maxGUARD family. Specic warnings
for specic tasks and situations are given at the appropriate
places in the documentation. Failure to observe the safety
notes and warnings may lead to personal injury and damage
to property.
All work may only be carried out by trained
electricians who are familiar with the safety
standards that apply to electrical engineering.
2.1 General safety notes
Work on the maxGUARD products may only be performed
by qualied electricians with the support of trained persons.
As a result of their professional training and experience, an
electrician is qualied to perform the necessary work and
identify any potential risks.
Before any work is carried out on the products (installa-
tion, maintenance, retrotting) the power supply must be
switched off and secured against being switched on again.
maxGUARD products do not contain any modules or compo-
nents that can be serviced by the user. If faults connected to
a maxGUARD product cannot be rectied using the recom-
mended measures (see chapter 11), the product in question
must be sent to Weidmüller. Weidmüller assumes no liability
if the product is tampered with!
Electrostatic discharge
maxGUARD products can be damaged or destroyed by elec-
trostatic discharge. When handling the products, the neces-
sary safety measures against electrostatic discharge (ESD)
according to IEC61340-5-1 and IEC61340-5-2 must be
observed. The packing and unpacking as well as the assem-
bly and disassembly of a device may only be carried out by
qualied personnel.
Open equipment
maxGUARD products are open equipment that may only be
installed and operated in lockable housings, cabinets or elec-
trical operations rooms. Only trained and authorised person-
nel may access the equipment.
The standards and guidelines applicable for the assembly
of control cabinets and the arrangement of data and supply
lines must be complied with.
Fusing
The operator must set up the equipment so that it is protect-
ed against overloading. The upstream fuse must be designed
such that it does not exceed the maximum load current.
The maximum permissible load current of the maxGUARD
products can be found in the technical data. The operator
must decide whether additional surge protection is required
according to IEC 62305. Voltages that exceed +/-30V may
cause the destruction of the modules.
Earthing
Products belonging to the maxGUARD family may be used
for earthed and non-earthed control voltage distributors.
Products belonging to the maxGUARD family do not have
a designated earth connection. Further information can be
found in section 4.5.
2.2 Intended use
maxGUARD is an electronic load monitoring system with
integrated potential distribution. It is used for the selective
overload and short-circuit monitoring of 24VDC control
circuits in the eld of programmable controllers or similar
control systems. Electronic load monitoring devices are used
for line protection. In case of a fault, the affected circuit is
switched off. The wire cross-section has to be dimensioned
according to the internal fuse (see section3.5).
The system must be operated with 24VDC safety extra-low
voltage (SELV, 18–30VDC) or protective extra-low voltage
(PELV).
An AMG ELM electronic load monitoring device can only
be operated in conjunction with a power-feed unit (AMG
FIM-0..., AMGFIM-C...). The potential distributors of the
maxGUARD family can be used for contact replication of the
load monitor output. Only Weidmüller ZQV4N cross-connec-
tors may be used for connections within a station.
All products belonging to the maxGUARD family are intend-
ed for use in equipment or machinery installed in enclosed
areas.
Installation in a suitable enclosure provides adequate pro-
tection against contact with live parts and also against the
ingress of dust and water (e.g. control cabinet, panel, con-
sole or similar). Mounting is only permissible on a prole
rail made of steel or galvanised steel in accordance with EN
60715 (TH35-7.5, e.g. Weidmüller TS35X7.5).
The products described in this manual may only be used for
the intended applications. If used for any other purpose, the
protective measures of the product may be rendered ineffec-
tive.
Any intervention in the products’ hardware or software other
than described in this manual may only be performed by
Weidmüller.
Observance of the documentation is also part of the intend-
ed use.

sure with a degree of protection of at least IP54 accord-
ing to IEC 60079-7.
–The housing enclosing the products must meet the
requirements of explosion protection type Ex na, Ex eb or
Ex ec.
–Prior to starting installation, ensure that no potentially
explosive atmosphere exists.
–If cut cross-connectors are used, AMG PP separation
plates must be inserted wherever there are bare cut
edges next to one another.
–If the temperature of a conductor or conductor entry
exceeds 70°C during rated operation, or 80°C at the
contact point, a conductor must be used that complies
with the temperature specifications as per the actually
measured temperature values.
–The products may only be operated in an environment
with pollution severity level 2 or lower in accordance with
IEC60664-1.
–A stabilised power supply (24VDC) with double or rein-
forced isolation must be used (SELV/PELV).
–A visual inspection of the maxGUARD station is to be per-
formed once per year.
–If a potentially explosive atmosphere exists, the following
applies:
–Live electrical connections may not be disconnected.
–DIP switches, binary switches and potentiometers may
not be operated.
2.4 Legal notice

maxGUARD is a modular system for building customised
24Vcontrol voltage distributors. It consists of electronic
load monitors, potential distribution terminals, and feed-in,
control and alarm modules.
The electronic load monitors selectively protect individual
load circuits against overload and short circuit. They are
available as xed-value variants or with an adjustable trip-
ping characteristic, as well as with a 2-pole output relay.
Active feed-in modules, control modules and alarm modules
are used to control and monitor the electronic load monitors.
Multiple control modules can be used to segment the control
voltage distributor into separate load groups. Alarm modules
can be used to transmit signals potential-free to external con-
trol boards.
All connections between the modules of a maxGUARD sta-
tion are established using cross-connectors. All connection
terminals are PUSH IN connections, are colour-coded and
have an additional 2 mm test socket.
A large number of the modules are available in two perfor-
mance classes:
–standard version with uncoated PCBs
–enhanced version with coated PCBs and enhanced certifi-
cation for maritime applications and applications in explo-
sive risk zones.

A maxGUARD station has three main internal connection
channels:
–+24V main strand for +24 V potential
–GND main strand for 0 V potential
–Internal signal line for communication
The two main strands are connected to the power supply via
a feed-in module and distribute the respective potentials for
the entire maxGUARD station.
The electronic load monitors form parallel junctions originat-
ing from the main strands.
Potential distribution terminals may be used to replicate the
outputs of the load monitors as required.
The internal signal line enables communication within the
maxGUARD station. Active feed-in modules, control modules
and alarm modules connect the internal signal line to an ex-
ternal control board.
All connections between the modules of a maxGUARD sta-
tion are established using cross-connectors.
The main connection channels are designed as double
channels. For high currents, the main strands must each be
equipped with two cross-connectors (see section4.4). If nec-
essary, the maxGUARD station can be extended by interleav-
ing the placement of the cross-connectors.
If a module cannot be connected to a specic main connec-
tion channel, the corresponding cross-connection contacts
will not be available. Installed cross-connectors will subse-
quently not be connected to the module and the individual
contact elements of the cross-connectors do not have to be
removed. White markings on the plastic tabs of the modules
indicate the active cross-connection sockets.

3.2 Functions
Overload advance warning
The adjustable load monitors are equipped with an overload
advance warning function.
If the output current of an adjustable load monitor exceeds
90% of the designated tripping current, this load monitor
couples an overload advance warning into the internal signal
line. The load monitor LED will ash green.
The overload advance warning can be transmitted to a con-
trol board via control modules or potential-free via alarm
modules.
Low voltage detection
Active feed-in modules, control and alarm modules as well
as all load monitors are equipped with low voltage detection.
If the input voltage of a load monitor falls below 18V, the
module LED will quickly ash red.
If the input voltage of a load monitor falls below 18V, the
load monitor will also disconnect the output.
If the input voltage falls below 15V, the module will power
down completely. The module LED will be off.
After power is restored, the module will automatically switch
to its last operational state prior to the undervoltage.
Surge detection
Active feed-in modules, control and alarm modules as well
as all load monitors are equipped with surge detection.
If the input voltage of these modules exceeds 31.2V, the
module LED will quickly ash red.
Overtemperature detection
The adjustable load monitors and the 4-channel load moni-
tors are equipped with overtemperature detection.
If an overtemperature is detected on a channel, the load
monitor will disconnect the output and couple an alarm
signal into the internal signal line. The load monitor LED will
illuminate orange (red and green simultaneously).
3.3 Type plate
Each module features a type plate, which includes identica-
tion information, the key technical specications and a block

3.5 Internal fuse
All load monitors are equipped with an internal fuse on the
PCB. If the electronic switch-off fails, the fuse will protect the
electronics and the external conductors against overload.
If the electronics are intact, the electronic switch-off will al-
ways be tripped rst.
The wire cross-sections must be measured ac-
cording to the internal fuse value, not the tripping
current of the electronic load monitor.
The wire cross-sections are to be measured according to
DINVDE0298-4. National regulations must be observed.
