Installation notes
Use the high-speed fuse specified
in the catalog according to the
connection example given.
- Applications with solid state power
units must also include an automatic
safety switch to cut out the load
power line.
For maximum reliability, it is essential
to install the device correctly in the
panel in order to have adequate heat
exchange between the sink and the
surrounding air by natural
convection.
Install the device vertically (max. 10°
inclination to vertical axis)
• Vertical distance between a device
and panel wall >100mm
• Horizontal distance between a
device and panel wall: at least 20mm
• Vertical distance between one
device and another: at least 300mm.
• Horizontal distance between one
device and another: at least 20mm.
Make sure that the cable channels
do not reduce such distances; if so,
install the groups cantilevered to the
panel so that air can flow
vertically on the heat sink
without obstructions.
Limits of use
• dissipation of thermal power of
device with restrictions on
temperature of installation site.
• requires exchange with outside air
or an air conditioner to transfer
dissipated power outside the panel.
• installation restrictions (distances
between devices to guarantee
dissipation by natural convection)
• max. voltage limits and derivative
of transients in line, for which the
solid state unit has internal protection
devices (depending on model).
• presence of dispersion current
< 3mA for SCR version GTSs and
< 4mA 4mA for Triac version GTSs.
(max. value with rated voltage
and junction temperature of 125°C).
