The SAM module is easily replaced. The input and output signal cables are equipped with modular
connectors. Common function channels are combined in groups.
The wires are connected using spring-cage terminal technology.
Two wires may be connected to one terminal when the wires are crimped in a double-wire ferrule.
For example, a Phoenix AL-TWIN 2* 0.75-10 may be used.
Connector modules are plugged together. The connector modules are equipped with
coding pins to preclude polarity reversal.

Admissible residual ripple less than 5% as per STANAG
1008.
Note: The processor is automatically reset if the voltage
falls below 7 V.
Below 7 W.
Without activated loads at SAM outputs
Additional output current on positive or negative conductor
shall not exceed 10 A DC in total.

• Wire diameter AWG14 (US) or 2.5 mm
recommended.
• Supply ground is common reference potential
(Common Ground) for all SAM electronics.
This applies to the entire I/O range with the exception
of certain electrically isolated channels.
• SAM electronics ground is not connected to housing
ground.
• Signal cable shields must be connected to housing
ground if applicable.
• Maximum direct current isolating voltage is 500
unless otherwise stated.
Value
• Horizontal (to facilitate legibility of fault display and
inscriptions on SAM housing).
• Note that space is required to connect cabling at the
top and bottom when installing the SAM in control
cabinets.
• The device heats up as a result of power loss. Heat
from the SAM dissipates through the back wall.
Ensure that heat can be conducted away from the
back wall of the SAM to the mounting frame. Do not
allow neighboring devices to additionally heat up the
SAM.
