Installation instructions
•
Disconnect the Hydrobox from the power supply.
•
Secure the interface next to the Hydrobox (wall mounting). Observe the instructions in the
figure below or install the interface in the Hydrobox (while following the
above safety instructions).
•
Connect the interface with the A B bus to any point on the bus. The A B bus is the bus
that connects the Hydrobox to the wired remote control. It is a two-wire bus that connects
connections A and B. The A B connection does not have a special polarity.
•
Connect the RS-485 bus to the RS-485 connection terminal of the interface.
•
After closing the Hydrobox, reconnect it to the power supply.
•
Follow the instructions in the user manual to configure and commission the interface.
•
Follow the instructions on the next page to configure the interface via the integrated DIP
switch.
NOTE
The cable for connecting the BMS-IFMB0AWR-E to the A B bus can be any two-wire cable insulated in accordance with
the specifications. The maximum distance for the A B bus is 50 meters. Further details can be found in the Hydrobox
user manual.
Observe the maximum distance of 500 meters for the bus; no loop or star topologies are permitted for the RS-485 bus;
a terminating resistance of 120 Ω must be present at each end of the bus in order to prevent signal reflections. A fail-
safe biasing mechanism must also be present.
IMPORTANT
•
Only ever use one remote control. No additional remote controls can be used if you
connect this interface.
• You cannot connect or mix Hydroboxes from series 4 and series 5.

Safety instructions
WARNING
Follow carefully these safety and installation instructions. Improper work may lead to serious harmful for your health and also may damage seriously the interface
and/or the Hydro unit.
 This interface must be installed by accredited technical personnel (electrician, installer, or technical personnel) and following all the safety instructions.
 Before manipulating the Hydro unit, be sure it is completely disconnected from Mains power.
 Do not modify the unit. (A fire or an electric shock may occur)
 This interface must only be installed in a restricted access location by user.
 Do not install the unit in any of the following places.
 Humid or wet place
 Dusty place
 Place exposed to direct sunlight
 Place where there is a TV set or radio within one meter
 Place exposed to rain (outdoors, under eaves, etc.)
 Use predefined cable and connect them certainly. Keep the connecting terminal free from external force.
It may cause an exothermic or a fire.
 Strip the insulation from the cable that connects to the connector (RS-485 and A B bus) following the dimensions shown in the diagram below.
 When connecting the cable to the connector (RS-485 and A B bus), ensure the core wires do not protrude from the connector.
 Use two-core cabtyre cable.
Installation instructions
 Disconnect the Hydro unit from Mains Power.
 Fix the interface beside the Hydro unit (wall mounting) following the instructions in the diagram below or install it inside the Hydro unit (respect the safety
instructions given above).
 Connect the interface to A B bus in any point of the bus. The A B bus is the bus that connects the Hydro unit and the wired remote controller, is a two-wire bus
connecting terminals A B of both, this A B connection has no specific polarity.
 Connect the RS-485 bus to the connector RS-485 of the interface.
 Close the Hydro unit and reconnect it to Mains Power.
 Follow the instructions on the user manual for configuring and commissioning the interface.
 Follow the instructions of the next page to configure the interface through on-board DIP-switches.
IMPORTANT:
 Use only one remote controller. A sub-remote controller cannot be connected when connecting this interface.
 It is not possible to mix and connect Hydro unit 4 series, 5 series, and R32 1 series (WM and AIO type).
 Group connection for BMS-IFMB0UEW-E is up to 6 units.
NOTE
The cable used for connection of BMS-IFMB0UEW-E to A B bus can be any two-core cabtyre cable, the maximum distance for bus A B is 50 meters, consult the
manual of the Hydro unit for more details.
Respect the maximum distance of 500 meters for the bus, no loop or star topologies are allowed for RS-485 bus, a terminator resistor of 120 Ω must be present at
each end of the bus to avoid signal reflections and also a fail-safe biasing mechanism.
NOTE
In its place there is a pair of cables to connect the Remote Controller. Use these cables to connect the AB bus. Check your Hydro unit user or service manual for
more information.
