3. Hardware Installation
3.1 Preparation
Make sure you have the following components ready before
beginning to install the ECU-B:
A dedicated standard AC electrical outlet (located as close as
possible of the PV array to ensure good communication between
ECU and microinverters).
A wireless router.
A smartphone or tablet with EMA Manager APP ready to use (see
page 10).
3.2 Selecting an Installation Location for the ECU-B
Choose a location that is as close as possible of the PV array.
The ECU-B is NOT rated for outdoor use. If installing outdoor,
ensure that the ECU-B is put in a waterproof box, and that the
antenna (wifi and Zigee) are placed outside of the box to ensure
optimum communication. In case you need to use extension
antennas to be closer to the PV array, please make sure the
extension antennas are Wifi 2.4GHz with SMA connectors
male/female. These extension antennas are not supplied by
APsystems, but can be purchased at any electrical/PV shop.
3.3 Installation
1)
Using a Wall Mount
When mounting the ECU-B to a wall, make sure to select a cool, dry
indoor location.
Depending on the wall surface you are mounting the ECU-B to, use
either two drywall screws or wall anchors, installed 100 mm apart
(The drywall screws and wall anchors are not included in the ECU-B
kit).
Align and slide the ECU-B onto the mounting screws.
