Installation

3.1

Overview of the commissioning steps

1. Install all components.
2. Establish a BUS connection (orange or white plug with designation
BUS or EMS).
You can find the information about a BUS connection of
an appliance checking the barcode.
3. Establish an IP-connection.
4. Switch on the heat source.
5. Wait approx. 2 minutes for a system configuration.
6. Plug in the power source to switch on the Gateway.
7. Wait approx. 15 minutes for a Gateway update.
8. Commission the required application (e.g. app).
3.2 Installation
▶ Remove cover ( Fig. 3, page 82).
▶ Mount the module ( Fig. 4, page 82).
▶ Secure the module ( Fig. 5, page 82).

Electrical connections

If a shielded LAN cable is used, this may lead in some rare
cases to problems with the BUS system. In such cases,
use an unshielded LAN cable as an alternative.
Connections and interfaces

Pre-assembling the ferrules and connecting the cable
▶ Open the grommets to match the cable diameter and cut in on one
side ( Fig. 8, page 83).
▶ Fit the ferrules and connect the cables (EMS:  Fig. 9, page 83;
CAN:  Fig. 10, page 83).
3.4

Connecting the BUS connections

If the maximum total length of the BUS connections
between all subscribers in a BUS system is exceeded,
the system cannot be commissioned.
If a ring structure is present in the EMS plus or EMS BUS
system, the system cannot be commissioned.
Maximum total length of the BUS connection between all subscribers
of the corresponding BUS system:
• EMS plus:
2
– 100 m at 0.50 mm conductor cross-section
2
– 300 m at 1.50 mm conductor cross-section
• EMS:
2
– 50 m at max. 2.50 mm conductor cross-section
• CAN:
– 30 m (shielded, twisted wires)
Suitable cables for the corresponding BUS system:
• EMS and EMS plus: e.g. LiYCY 2 x 0.75 (TP)
2
• CAN: 2 × 2 × 0.3 mm ; shielded, twisted wires
▶ All LV leads must be routed separately from cables carrying mains
voltage to avoid inductive interference (minimum separation
100 mm).
Connecting the EMS and EMS plus BUS system to the module
▶ Connect BUS subscribers with two BUS connectors in series
( Fig. 6, page 83) or BUS subscriber [B] with one junction box [A]
in a star configuration ( Fig. 11, page 83).
▶ In case of external inductive interference, shield the cables.
This ensures that the cables are shielded from external interference
(e.g. heavy current cables, overhead wires, transformer stations,
radio and television set, amateur radio stations, microwave ovens
etc).
