Tab. 9-3: Pin assignment of the voltage supply plug X1S
Destruction of screw terminals, insufficient con-
tact and loss of UL/CSA certificiation if no cop-
per wire is used and/or wrong tightening tor-
que.
NOTICE
For terminal connectors use copper wire only. Tighten the screws of the screw
terminals with a torque of 2.25 lb in (0.25 Nm).
Damage to the Embedded Terminal caused by
polarity reversal when the 0 V load is simultane-
ously grounded.
NOTICE
Polarity reversal of the X1S plug can destruct the operator terminal if there is no
additional external protection (fire hazard). This is caused by grounding the 0 V
in the operator terminal and simultaneously by grounding the 0 V load (PELV).
Damage to the Embedded Terminal caused by
polarity reversal and input voltages that are too
high.
NOTICE
The Embedded Terminals are designed reverse voltage protected. Polarity rever-
sal of the 24 V voltage supply at the X1S does not damage the device. Overvolt-
age more than 36 V and more than 500 ms damages components in the power
supply area of the device.
9.6 Slot for Compact Flash Card XCF1 and XCF2
The Embedded Terminals are provided with two slots for Compact Flash cards
("XCF1" and "XCF2"). The slots are designed for Compact Flash cards of type A
and type B. A Compact Flash card with the operating system is provided upon
delivery. Further cards can be ordered separately (see
