PROFILE
Zero crossing relay with antiparallel thy-
ristor output is the most used solid state
relay in industrial applications.
In fact, it can be used for resistive, inducti-
ve and capacity loads.
“Zero crossing” relay is energised when
voltage meets the zero point and disener-
gised when current meets the zero point,
depending on the signal control on the
input circuit.
This relay has been designed to stand
high-value transitory applications .
When the relay has to stand high currents
for a long period, it is necessary to grant a
proper dissipation and an adequate elec-
trical connection between relay terminals
and the load.
Varistors, fuses, thermostats and fans are
available as fittings.
Use the relay with an opportune heatsink
(see section accessories).

Heatsink Thermal Resistance Calculation
Rth = (90°C - T.amb. max) / Pd
where Pd = dissipated power
Max. amb. T = max air temperature inside the
electrical cabinet.
Use a heatsink with thermal resistance inferior
to the calculated one (Rth).

Installation notes
The device must be protected by a high speed
fuse (accessory).
Applications with power solid state relays must
also have a switch to isolate the power line.
Protect the solid state relay against overheating
by using a heatsink (accessory).
The heatsink must be sized according to room
temperature and load current (see technical
data).
Heatsink installation procedure:
spread 1 gram of thermoconductive silicone
paste (we recommend DOW CORNING 340)
on the dissipative metal surfaces of the module.
The surfaces must be clean and the thermocon-
ductive paste must not contain any impurities.
As alternative it is also possible to use the slide
SIL-GQ available as accessory.
Alternately tighten the two fastening screws
until reaching a torque of 0.4…0.6 Nm.
Wait 5 minutes for any excess paste to run off.
Alternately tighten the two fastening screws
until reaching a torque of 1.2…1.4 Nm.
Attention
The contact surface of the heatsink module
may have a maximum planarity error of 0.1 mm
and maximum roughness of 0.02 mm.
The fastening holes on the heatsink must be
threaded and countersunk.
The heatsink must be grounded.

WARNING: this symbol indicates danger.
Before installation, please read the following advices:
• follow the indications of the manual scrupulously when making the connections to the instrument.
• use a cable that is suitable for the ratings of voltage and current indicated in the technical specifications.
• if the instrument is used in applications where there is risk of injury to persons and damage to machines or materials, it is essen-
tial that it is used with an auxiliary alarm device.
It is advisable to verify frequently that the alarm device is functional even during the normal operation of the equipment.
• The instrument must NOT be used in environments where there could be the presence of dangerous atmospheres (inflammable
or explosive).
• During continuous operation, the heatsink may reach 100°C and remain at a high temperature due to thermal inertia even after
the device is switched off. Therefore, DO NOT touch the heat sink or the electrical wires.
• do not operate on the power circuit untless the main supply is disconnected.
• DO NOT open the cover if device is “ON”!
(use the holes in the cover for eventual re-calibration).
Installation:
• connect the device to the ground using the proper ground terminal.
• the power supply wiring must be kept separate from that of inputs and outputs of the instrument; always check that the supply
voltage corresponds to that indicated on the instrument cover.
• evitare la polvere, l’ umidità, i gas corrosivi, le fonti di calore.
• keep away from dust, humidity, corrosive gases and heat sources.
• The connection cable must be shorter than 3 meters if the current transformer is used.
Maintenance: Check the correct operation of the cooling fans at regular intervals; clean the ventilation air filters of the installation
at regular intervals.
• Repairs must be performed only by specialized or appropriately trained personnel. Cut off power to the device before accessing
internal parts.
• Do not clean the box with solvents derived from hydrocarbons (trichloroethylene, gasoline, etc.). Using such solvents will compro-
mise the mechanical reliability of the device. To clean external plastic parts, use a clean cloth wet with ethyl alcohol or water.
Technical service : GEFRAN has a technical service department. Defects caused by use not conforming to the instructions are exclu-
ded from the warranty.
