Supply voltage control shall be ensured. The supply voltage
must be equal to the voltage value on the rated plate.
REQUIRED SPACING
While performing assembly tasks in the electric cabinet, it is
necessary to maintain proper distance from heat sources.
PROTECTION FROM SUNLIGHT
The electric cabinet shall be protected from direct sunlight.
TERMINAL CURRENT LOAD
Terminal current load shall be observed.
PROTECTION OF RELAY CONTACTS
The risk of welding together: the relay contacts beyond the
connecting area shall be provided with an overcurrent protec-
tion with activation amperage equal to the maximal permitted
current of relay contact. Do not overload SSZ-RZ4 and SSZ-RZB
control units. The specified switching (load) current shall not
be exceeded.
IN CASE OF ANY FAILURE, SWITCH OFF THE UNIT!
SSZ-RZ4 or SSZ-RZ4B control unit shall be switched off in case
of any failure or defects.
DO NOT USE THE CONTROL UNITS IN POTENTIALLY EXPLO-
SIVE (ATEX) ZONES
SSZ-RZ4 nor SSZ-RZ4B control unit can mot be used in zones
with explosion hazards (ATEX zones).
THE RISK OF INJURY FROM ELECTRIC SHOCK!
Both before and during the mounting works of SSZ-RZ4 and
SSZ-RZ4B control units, all the electric machines/devices to be
connected must be switched off from voltage supply.
OPERATION FAILURE DUE TO OVERHEATING
A pressure-sensitive product (SSZ safety mat, SSZ safety edge
or SSZ safety bumper) functions may be disturbed in result of
control unit overheating. A safety unit shall be mounted in en-
closures with IP54 as minimal protection index (e.g. in control
cabinets).
TERMINAL ASSIGNMENT
Terminal assignment shall be observed when connecting the
supply voltage
PROTECTION OF RELAY CONTACTS
Any changes shall be forbidden in control unit
setting or structure.
The machine shall not be switched on in
case of any hazard! Failure to respect these
recommendations may be hazardous to health
or even life-threatening!
The CE declaration of conformity is not valid
when devices or control units, other than SSZ,
are connected.
SAFETY RECOMMENDATIONS
THE SCOPE OF DELIVERY
1 x safety unit
An enclosure with an electronic module and plug-in connec-
tions
1 x operating manual
Immediately after delivery is received, it shall be checked for
completeness and visual status.
Danger of contact welding Relay output shall additionally be
external protected
DO NOT OVERLOAD CONTROL UNITS
It shall be ensured that contact current is not exceeded.
MAINTAINED REDUNDANCY
It shall be ensured that all connections are made within the
circuit or that another control unit.
