Strain Relief and Terminal Block Cover
Strain relief and terminal block cannot be used with -WD models.
In certain jurisdictions, terminal block covers are required to meet local safety regulations. Strain reliefs and terminal block covers are available for con-
trollers housed in large enclosures and are used to relieve tension on the wiring and conceal the controllers' wire terminals. Strain reliefs and terminal
block covers are optional and are sold as peripherals. Strain relief and terminal block covers usage does not comply with DIN rail mounting.
Installing the strain relief and terminal block cover
Prior to connecting all wires, it is recommended to install the strain relief. Two screws are provided for its installation under the bottom part of the enclo-
sure as shown below.

Tie wraps can then be used to group wires together and attach them securely to the strain relief in an effort to relieve undue tension. Distech Controls
recommends using 0.184'' (4.6 mm) wide tie wraps with a 50 lbs (220 N) tensile strength to attach wires to the strain relief.
