10 Mounting and connection
Mount the module on a 35 mm DIN rail according to
EN60715.
When using the TBUS DIN rail connector to redirect the di-
agnosis power supply, insert it into the DIN rail first.
Figure 9 Mounting and removing

11 Startup
Apply the rated control supply voltage to terminals A1/A2
(with active error acknowledgement) or A1'/A2 (without ac-
tive error acknowledgement). The PWR LED lights up.
Enabling current path 13/14 (or 13F/14) closes, and confir-
mation current path 31/32 opens.
In this case, it is vital to observe the mounting
direction of the module and DIN rail connec-
tor:
