1.4 Mounting in a control panel
Mount the device away from heat
sources and avoid direct contact
with corrosive liquids, hot steam or
the like.
Provide a free space of 10 mm all
around the device for its ventilation.
The device should be mounted so
that the terminals are out of the
reach of the operator and cannot be
touched by him. When mounting the
device, consider the fact that only
the front side is classified as acces-
sible for the operator.
1.5 Mounting instructions
1. Remove the mounting clip from the device.
2. Insert the device from the front into the panel
cut-out, ensuring the front-panel gasket is
correctly seated.
3. Slide the fixing clip from the rear onto the
housing, until the spring clamps are under
tension and the upper and lower latching lugs
have snapped into place.
Note: In case of proper installation, IP65 can be
reached on the front side.
1.6 Electrical installation
This device is powered by an internal battery.
The device must be disconnected
from any power supply prior to any
installation or maintenance work.
Make sure that no more voltages
LIABLE TO CAUSE AN ELECTRO-
CUTION are present.
Installation or maintenance work
may only be carried out by qualified
personnel and in compliance with
the applicable national and internati-
onal standards.
Take care to separate all extra-low
voltages entering or exiting the
device from hazardous electrical
conductors by means of a double or
reinforced insulation (SELV circuits).
The device must be protected exter-
nally for proper operation. Informa-
tion about the prescribed fuses can
be found in the technical data.
The relay output is not protected /
overcurrent-limited internally in the
device. Without suitable protection
of the relay output, undesired heat
development or even fire may
occur. The relay output must be
protected externally by the manuf-
acturer of the plant. It must also be
made sure that, even in case of a
malfunction, the values stated in the
technical data are under no circum-
stances exceeded.
During installation, make sure that the voltage
of the counting and reset inputs and the wiring
of the output contacts are both powered by the
same mains phase, in order not to exceed the
maximum permitted voltage of 250V.
The cables and their insulation must be desi-
gned for the planned temperature and voltage
ranges. Regarding the type of the cables,
adhere to the applicable country and final device
standards. The cross sections allowed for the
screw terminals can be found in the technical
data.
Before starting the device, check the cables
for proper wiring and tightening. The screws of
unused screw terminals must be screwed to the
stop, so that they cannot loosen and get lost.
