The external voltage supply must have a rated voltage of 24 V and
must not exceed an output voltage of 30 V.
DANGER
⇒ The DC 24 V input voltage must comply with the requirements of the "Pro‐
tective separation"!
⇒ Plug and unplug the connector only if there is no voltage!
Fig.7-4: Safety transformer according to EN 60742
Interfering AC voltage components such as the ones resulting from an uncon‐
trolled three-phase bridge circuit without smoothing and with a ripple factor (see
DIN 40110/10.75, section 1.2) of 5 % are allowed.
That results in the greatest absolute value of 30.2 V as upper voltage limit. The
lowest obsolete value of 18.5 V is the lower voltage limit.

Fuse drops
● Simultaneous short-circuit of several outputs
(connector 11) against 0 V
● Simultaneous exceeding of I = 200 mA at several
outputs (X11)
● Hardware defect
● Short-circuit of the 24 V supply of the hand-held
terminal (connector X81, pin 1 or pin 14) against
0 V
