Installation
Wall Installation
FixtheDINrailhorizontallytothewallusingscrews.
Installation
1.PlacetheSymondoBoxontheupperedgeoftheDIN
railwiththelockingcatchontop.

2Engagethedevicebypressingitdown.Ensurethatthe
lockingcatchesengagecompletelyandthatthedeviceis
firmlyseatedontherail.

Disassembly
RemovetheSymondoBoxfromtheDINrailbyinsert-ing
twoscrewdriversintotheeyeletsandpullingthemdown-
wards.
Separation walls and cover

Theseparationwallsandthecovercanberemovedforeasier
connectionofthecables.Theymustthenbereinstalledin
ordertosafelyseparateareascarryingmainsvoltagefrom
areascarryinglowvoltages.

Openthecover(90°degree)andthenpullitoutofthesideof
theattachment.
Iftheterminalblocks(B-I)aretobesuppliedwithavoltageotherthanthemainsvoltage,proceedasfollows:
1. RemoveexistingbridgesA1-B1andA2-B2
2. ItisabsolutelynecessarytoinsertaseparatingwallbetweenA-B.
3. ConnectthepowersupplytoB1(L)andB2(N).
4. Observemax.switchingpowerofrelayandfuse(4AT)

Electrical Connection
Low-voltagecablessuchastemperaturesensorcablesmustberoutedseparatelyfrommainsvoltagecables.

Beforeworkingontheunit,switchoffthepowersupplyandsecureitagainstbeingswitchedonagain!Checkthatthereis
nopowerflowing!Electricalconnectionsmayonlybemadebyaspecialistandincompliancewiththeapplicablereg-
ulations.Theunitmaynotbeputintooperationifthereisvisibledamagetothehousing,e.g.cracks.

Thecustomermustprovideanall-poledisconnectingdevice,e.g.anemergencyheatingswitch.

 Thestrainreliefsaresuitableforflexiblecables
withacablesheathdiameterof5mmto8mm,
primarilyusingthelowerstrainrelief(as
shown).Thecablesmustbecheckedforfirm
placement.Solid,thickerandthinnercables
mustalwaysbelaidfirmlyandmustbefixedon
theinstallationside.
 Massivewiresorcableswithspecialwireend
sleevescansimplybepressedintotheter-
minals.Forotherwires,thetrowelmustfirstbe
completely pressed onwithascrewdriveras
shown.

Wireferrulesmadeofbrasscanbe
difficulttoclampduetotheirasym-
metriccrimpingshape.Inthiscase,
removethewireferrule.Theplug-in
terminalsarealsosuitableforflexible
cables.

coolingonly(SymondoController/SymondoBox).

Example 1: Line structure with Symondo Box as end point.

A120OhmterminatingresistormustbesetonthefirstandlastdeviceintheCANnetwork.

12

Connection example apartment building
Example: Line structure with several Symondo Box via the building CAN bus (e.g. across several residential or com-
mercial units).
Usebuilding CAN busonterminal block Msothatnoprivatedatasuchasroomtemperaturesorholidaymodeare
sharedacrossflats.

Whenconnectingthe1-Wiresensors,pleaserecordthe16-digit1-WireIDandthelocationofthesensorforlater
commissioningofthesystem!The1-WireIDcanbefoundinthedevicehousingandinthedevicemenuunder:
Devices->SymondoBox->Resources->1-WireSensor.

Example 1: Line. The installation leads from one sensor to the next. A twisted pair cable must be used for the connecting
cable.
Example 2: Tree Structure. A twisted pair cable must be used for the connecting cable.
