Heat Dissipation

To allow adequate heat dissipation, always leave a spacing of 10 cm (3.94 in.) between the short-circuit protection devices and the TeSys island starters.

Additional installation recommendations pertain under the following conditions:

  • Three or more starters are mounted on the TeSys island side-by-side.

  • The starters have ratings (le) greater than or equal to 25 A.

  • The starters are used with a motor having a nominal current In > 85% x le.

Under these conditions, we recommend that you implement one of the following installation rules:

  • Option 1: Using the engineering tool, reorganize the avatars on the TeSys island to avoid these conditions.

  • Option 2: Use 50 cm (1.64 ft) cables to wire the short-circuit protection devices with the affected middle starters. In a group of three starters, which all meet the conditions itemized above, the extra length is only recommended for the starter in the middle. In a group of four starters, the extra length is only recommended for the two starters in the middle.
