Relay Box for Infrared Cabins - Installation Instructions
39
Installation
You can connect multiple IR emitters to each of the terminals IR-1, IR-2 and
IR-3. The IR emitter lines must all have the same cross-section.
The total output of IR-1, IR-2 and IR-3 together may not exceed 3.5 kW. Rec-
ommendation:
If terminals IR-1 and IR-2 together have a load of less than 2.3 kW, IR-3 can
accept a maximum switching load of up to 1.2 kW. In this case, the fuse at
F2 (T4A H 250V) must be replaced by a T6.3 A H 250 V fuse.
If you connect more than one emitter per heating circuit, you must con-
nect all lines to a plug-in module outside the relay box.
Example – plug-in modules (optional)
