DANGER
Exceeding the permitted process or supply voltage range (< -35 V DC or > +35 V DC) could lead to unrecoverable damage of the system.
DANGER
For the supply of the modules, power supply units according to PELV or SELV specifications must be used.
NOTICE
The creepage distances and clearances meet the requirements of the overvoltage category II, pollution degree 2.

-
Terminal bases: Maximum 2 communication modules allowed.
-
Digital inputs: Maximum number of simultaneously switched on input channels limited to 50 % per group (e.g., 8 channels => 4 channels).
-
Digital outputs: Output current maximum value (all channels together) limited to 50 % per group (e.g., 4 A => 2 A).
-
Analog inputs: No limitations.
DANGER
Safety value calculation uses the average temperature. The average temperature for both the extended temperature range (-40 ... +70 °C) as well as for normal temperature range (0 ... +60 °C) is defined to +40 °C.
Ensure that average operating temperature for used AC500-S and AC500-S-XC modules does not exceed +40 °C.

NOTICE
In order to prevent malfunctions, it is recommended that the operating personnel discharge themselves prior to touching communication connectors or perform other suitable measures to reduce effects of electrostatic discharges.
NOTICE
Unused sockets for communication modules on terminal bases must be covered with TA524 dummy communication module. I/O bus connectors must not be touched during operation.
