6. Reliability
The redundancy module does not include electrolytic capacitors. Therefore, the lifetime expectancy and MTBF
value are extremely high.

*) The Lifetime expectancy shown in the table indicates the minimum operating hours (service life).
**) MTBF stands for Mean Time Between Failure, which is calculated according to statistical device failures, and indicates reliability of a
device. It is the statistical representation of the likelihood of a unit to fail and does not necessarily represent the life of a product.

Instructions:
a) The external circuitry of all terminals (including signalling contacts) must meet the safety requirements stipulated by
IEC/EN/UL 60950-1: SELV.
b) Use appropriate copper cables that are designed for minimum operating temperatures of:
60°C for ambient up to 45°C and
75°C for ambient up to 60°C minimum.
c) Follow national installation codes and installation regulations!
d) Ensure that all strands of a stranded wire enter the terminal connection!
e) Up to two stranded wires with the same cross section are permitted in one connection point.
f) Screws of unused terminal compartments should be securely tightened.
g) Ferrules are allowed, but not required.
h) Do not connect or disconnect the wires from the terminals below -25°C (-13°F).
