Test switch modules for RET 521
7HVW VZLWFK PRGXOHV IRU 5(7
One test switch is required for each Analog input module (AIM). As the RET 521 is 3/
4 of a 19" case, the first test switch is mounted alongside the terminal. The second test
switch is delivered separately, with a set of leads and must be connected by the user in
accordance with the circuit diagram of each terminal. The conductors are dimensioned
for connection to the adjacent rack. The test switches for RET 521 always have internal
star point earthing.
