
Cables with high rigidity, such as armored cables, are not recommended as DC input
power cables, because poor contact may be caused by the bending of the cables.

The metal contacts supplied with the DC connectors are either cold forming contacts or
stamping forming contacts. Crimp the metal cold forming contacts using crimping tool
UTXTC0005 (Amphenol, recommended) or H4TC0001 (Amphenol). Crimp the metal
stamping forming contacts using crimping tool H4TC0003 (Amphenol, recommended) or
H4TC0002 (Amphenol).

Before assembling DC input connectors, label the cable polarities correctly to ensure
correct cable connections.

After crimping the positive and negative metal contacts, pull the DC input power cables
back to check that they are connected securely.

Insert the crimped metal contacts of the positive and negative power cables into the
corresponding positive and negative connectors. Then pull back the DC input power cables
to check that they are connected securely.
