Multiple units on multiple power point can be used if longer heating
cables are required. Up to 9 units can be connected on three phase
systems via the network configuration.
2.1 Disassembling the unit
Always switch off the mains supply (circuit breaker) before opening the
unit. Several touchable parts inside the unit are directly connected to
the mains voltage.
The HWAT-ECO has a removable top lid. Both top and bottom of the box
have electronic parts and are connected to each other by a 14-pin
connector. First unscrew the four screws in the lid. Pull the lid carefully
upwards, not sideways! Inside the unit an ABS separation sheet will help
to guide the connector when disconnecting. See 5.5 Diagrams

and
H
Closing the box
Position the lid in front of the wall-mounted bottom unit. The separation
sheet inside the unit will help to guide the lid and the connector. Push
the lid gently towards the bottom unit, the last part will offer some
resistance because of the connector pins.
2.2 Wall mounting instructions
The unit has two mounting options.
1. Inside the bottom part there are two holes, with the two supplied
screws and sealing rings the unit can be mounted to a wall.
2. The second mounting option is DIN-rail mounting. For both options
see the diagram with ruler on the flip-out cover page.
