Terminal tightening and wire specifications for the VLT 2800 and
VLT 6000 are defined in Table I.

Mounting requirements
Mount the BACLink enclosure as required using the predrilled
mounting holes (see Figure 2). The unit weighs approximately
15.3 pounds (7 kg).
For BACLink portals ordered without an enclosure, mount the unit
in an enclosed panel using the mounting holes provided on the
BACLink portal backplate (refer back to Figure 1). Leave about 2
inches (5 centimeters) on each side for wiring access. In addition,
the BACLink portal requires 24 VAC input power.
BACLink portal is a Class 2 device (less
than 30VAC, 100VA maximum). Take
appropriate isolation measures when
mounting BACLink portal in control panels
where non-Class 2 devices (for example,
120VAC) or wiring are present.
