Switches S201, S202, And S801 - Danfoss FC 300 Design Manual

FC 300 Design Guide
Aluminium conductors
Aluminium conductors are not recommended. Terminals can accept aluminium conductors but the con-
ductor surface has to be clean and the oxidation must be removed and sealed by neutral acid free Vaseline
grease before the conductor is connected.
Furthermore, the terminal screw must be retightened after two days due to the softness of the aluminium.
It is crucial to keep the connection a gas tight joint, otherwise the aluminium surface will oxidize again.

Switches S201, S202, and S801

Switches S201 (A53) and S202 (A54) are used to
select a current (0-20 mA) or a voltage (-10 to 10
V) configuration of the analog input terminals 53
and 54 respectively.
Switch S801 (BUS TER.) can be used to enable
termination on the RS-485 port (terminals 68 and
69).
See drawing Diagram showing all electrical termi-
nals in section Electrical Installation.
Default setting:
S201 (A53) = OFF (voltage input)
S202 (A54) = OFF (voltage input)
S801 (Bus termination) = OFF
When changing the function of S201,
S202 or S801 be careful not to use
force for the switch over. It is recom-
mended to remove the LCP fixture
(cradle) when operating the switches.
The switches must not be operated
with power on the frequency convert-
er.
