ABB TB511-ARCNET Terminal base



ABB TB511-ARCNET Terminal base
Extreme situations

Terminal blocks suitable for extreme environmental conditions without XC version markings.

Figure 3 (see part number 1SAP3... (label)) is used to identify the XC version.

Tips!

Not using wall mounted accessories will damage the module!

During screw assembly, using wall fittings (TA526) can prevent module bending and damage.

The wall fitting TA526 must be inserted.

1. Similar to a DIN rail, fasten TA526 into the rear of the module. A TA526 rotates 180 degrees.

2. Use screws (M4, maximum torque of 1.2 Nm) to tighten the module from the front end.

Tips!

There is a risk of corrosion!

If XC equipment is used in a salt spray environment, idle connectors and slots may be corroded.

For XC device TA535, idle connectors and slots should be protected with TA535 protective covers.
