(a)
The Ethernet cable delivered as an accessory is 1 m long.
It is, however, possible to use a field-supplied Ethernet
cable. In this case, respect the maximum allowed distance
between LAN adapter and router, which is 50 m in case of
Cat5e cables, and 100 m in case of Cat6 cables.
(b)
These wires MUST be sheathed. Recommended strip
length: 6 mm.
(c)
These wires MUST be sheathed. Recommended strip
length: 6 mm.
(d)
All wiring to X1A MUST be H05VV. Required strip length:
7 mm. For more information, see
"4.2.4 Digital inputs" on
page 5
.
4.2.1
Router
For the connection of the LAN adapter, the router requires a free
LAN port.
The minimum category for the Ethernet cable is Cat5e.
4.2.2
Indoor unit
For power and communication with the indoor unit, the LAN adapter
is to be connected to the indoor unit via a 2‑wire cable. There is NO
separate power supply: the adapter gets its power from the indoor
unit.
4.2.3
Electrical meter
If the LAN adapter is connected to an electrical pulse meter (field
supply), make sure the meter meets the following requirements:

4.2.4
Digital inputs
Connector X1A is for the connection of the LAN adapter to the digital
inputs of a solar inverter / energy management system, and allows
for use of the Daikin Altherma system in various Smart Grid
applications.
X1A/N+L supply a detection voltage to the input contact of X1A. The
detection voltage enables the detection of the state (open or close)
of the digital inputs, and does NOT supply power to the rest of the
LAN adapter PCB.
Make sure X1A/N+L are protected by a fast acting circuit breaker
(rated current 100 mA~6 A).
The rest of the wiring to X1A differs depending on the Smart Grid
application. For more information, see
"7 Smart Grid application" on
page 11

Installation
5.1
Overview: Installation
The installation of the LAN adapter consists of the following stages:
1
Mounting the rear casing to the wall
2
Mounting the PCB to the back casing
3
Connecting electrical wiring
4
Mounting the front casing to the back casing
5.2
Mounting the LAN adapter
5.2.1
About mounting the LAN adapter
The LAN adapter is mounted to the wall by way of the mounting
holes
(a)
in the rear casing. Before mounting the rear casing to the
wall, you have to remove some knockout holes
(b)(c)
, depending on
how you want to route the wiring and insert it into the adapter.
You can route and insert the wiring from the bottom or from the rear.
Respect the following rules and restrictions:
Wiring
Possibilities and restrictions
Wiring routed and inserted from
the bottom
▪ ONLY for surface wiring routed
from the bottom.
▪ When routing wiring from the
bottom, ALWAYS let it enter
the adapter via the holes in the
bottom of the casing
(b)
. It is
NOT allowed to clamp this
wiring between the casing and
the wall and let it enter via the
holes in the rear
(c)
.
▪ The wiring for X1A and X4A
MUST be routed and inserted
from the bottom. The wiring for
X2A and X3A CAN be routed
and inserted from the bottom
(or from the rear).
▪ When routing and inserting
wiring
from
the
bottom,
remove the required knockout
holes in the bottom of the
casing
(b)
and replace them
with the grommets from the
accessory bag.
