wire lead should be securely attached inside the connector. You should be able to pull on the wire and not
dislodge it.
Warning. For both 24V and -48V input voltages, the positive (+) wire of the sourcing equipment, such as
a battery or rectifier, must be connected to the positive (+) terminal of the OmniSwitch DC power supply
and the negative (-) wire of the sourcing equipment must be connected to the negative (-) terminal of the
OmniSwitch DC power supply. This rule always applies to both 24V, and -48V input voltages, regardless
of the polarity signs shown on the power supply specification labels such as: -48V, +24V, or -24V."
