Due to its protection degree (IP65), the StecaGrid inverter can be installed in
numerous locations. During installation, a number of points must be observed
however and are listed as follows.
• Because the device can make a small humming/rushing noise (< 3 dBA) it
should not be installed in living areas.
• The inverter must not be installed in areas where animals are kept (risk to ani-
mals and/or risk to the electrical system because of the animals and because
of increased dust formation, damage to cables from ammonia, etc.).
• The combination of 1 master unit and  slave units can generate high cur-
rents. Adapt the connection accordingly. During the installation of 1 master
unit, it is recommended that preparations are made to the connection to
allow possible expansion with slave units.
• The LED and display must remain readable (reading angle).
• The ambient temperature must remain between –5 °C and 60 °C
(recommended: 40 °C).
• The equipment must not be exposed to direct sunlight. If necessary, the
equipment must be protected against direct sunlight by placing a special
shield in front of and above the equipment.
• There must be sufficient ventilation.
• The installation position of the inverter will be described in the next section. This
installation position must be adhered to.
The last 4 points are important in order to minimise the probability of derat-
ing occurring. If these points are not taken into consideration this may result in
reduced yield.
4.3 Installation
The StecaGrid has been designed to stand vertically. Because of the risk of faults
occurring to the cooling system, deviation from the perpendicular must not be
more than +/- 15°. We therefore recommend that it is not installed horizontally
(on its side).
The inverter is provided with a (separate) mounting/fixing plate. Each plate con-
tains two connecting hooks that can be used to connect a following mounting
plate perfectly. Each mounting plate is also provided with hooks that project out
at the front on which the inverter is hung.
When installing the StecaGrid, choose a flat background which is not easily flam-
mable, e.g. a concrete or stone wall.
First fix the mounting plate using 4 screws (ø 5 mm, not supplied). When

doing so, please note the width of the junction box of the master; this box
1
projects out 1.5 cm on the left. A space of approx. 3 cm must also be left
so that the junction box cover can be opened. For each slave unit that is
connected to the master (max. ; the slave units are hung to the right of
the master), an additional mounting plate must be provided. The mount-
ing plates must be connected with each other exactly using the connection
hooks.
Then the master inverter can be hung. Allow the inverter to slide onto the

hooks projecting out at the front from above. Make sure that the locking
2
mechanism drops over the cooling plate fin. This will prevent the inverter
from falling to the floor, e.g. due to accidentally lifting up the inverter.
