UK Installation
It is possible to install only one insulation monitoring device for
each independent supply line. Fasten the device onto DIN rail
(35 mm) using a proper fixing system on the rear.

A. Auxiliary supply (rated voltage 115/230 V 50-60Hz)
B. Error / Link Fail
C. Insulating resistance and impedance measurement
D. Output for remote signalling panels
E. Serial output RS485 (only for ISOLTESTER-DIG-PLUS)
F. Temperature sensor 2
G. Temperature sensor 1
H. Current transformer .../5 A input
