ATTENTION
The case controller may only be mounted on a Cap (DIN) rail and operated as an integrated regulation
and control device (EN60730). Power loss of the controller is approx. 11 VA, which needs to be taken
into account when installing the unit.
All leads running to and from the case controller - especially those of the CAN bus - must be shielded
(cable type: LiYCY)! No shielding is required on sensor leads when installed exclusively
inside the refrigerated display case and when external interference (for example from parallel power
wires) is not to be expected (see operating instruction “ Grundlagen und allgemeine Sicherheits- und
Anschlusshinweise ”). As a general rule, care should be taken to ensure that signal leads and leads
carrying a supply voltage are routed through separate cable channels.
