Bulletin 1694 Electronic circuit protection for 24V DC
(Cat xxxx-xxx)
WARNING: Electrostatically sensitive sub-assemblies can be destroyed by voltages far below the human perception threshold. These voltages already occur if you touch a component
or electrical terminals of a sub-assembly without being electrostatically discharged. The damage of a sub-assembly caused by an overvoltage is often not immediately
recognised, but will be noticed only after a longer operating time.
Mounting or actuation of the 1694 connector arm must only be effected at dead-voltage. For start-up the 1694 connector arm must be closed.
Device to be installed, operated and maintained by trained personnel only.
The device can’t be serviced or repaired.
To secure device properly against unintended access, product shall be mounted in locked cabinet.

Temperature factor / continuous duty
Temperature factor table:
The time/current characteristic depends on the ambient temperature. In order to determine the max. load current,
please multiply the current rating with the temperature factor and consider the factor for side-by-side mounting.
ISC - short circuit current
Please note
- When mounted side-by-side, the devices can carry max. 80 % of their rated load or a different rating has to be selected.
- With high temperatures, the load current warning threshold “warn limit typically 0.9 x IN” will be reduced in accordance
with the temperature factor.
- Selection of current rating of the circuit protector ≤ rating of power supply.

General recommendation for all 1694 modules installation.
Small opening above the screwdriver insert (marked as 2.1 and 2.2) = voltage measuring point.
Larger opening under the screwdriver insert (marked as LOAD +) = wire connection area.
Screwdriver for installation: blade-style screwdriver size 1 for smaller Push-in terminal (PT 2.5) inserts.
Mounting position: horizontal mounting position is preferred.

General data - common for 1694-PFx / 1694-DMx
Power Feed 1694-PFx: Power Feed Module receives the DC 24 V supply voltage, e.g. from a switched mode power supply,
and distributes it to the mounted circuit protectors via the integral connector arm of the 1694-PM.
(The potential-free auxiliary contact in the 1694-PFA1244 indicates any detected failures through the circuit protector,
e.g. to the superordinate control unit (CPU).)
Distribution Modules 1694-DMx: For terminal multiplication to add multiple wires for + and – 24VDC
