Note: Certain TB plugs are equipped with captive
screws for securing the assembled cable’s
TB plug to the unit’s VDC-IN connector (C and
E types only). To secure the plug, tighten the two
screws on the plug into the corresponding holes
on the sides of the input connector as shown in
Figure 3.
DC Power Supply Wire Voltage Polarity
Refer to Figure 4 for proper mapping of the power supply
wire leads to the TB plug’s three terminals.
Warning:
Reversing the wire voltage polarity can cause damage to
the unit!
Always connect a ground (earth) wire to the TB plug’s
Chassis (frame) Ground terminal. Connecting the unit
without a protective ground, or interruption of the
grounding (for example, by using an extension power cord
without a grounding conductor) can cause harm to the unit
or to the equipment connected to it!
