Attention

■

To protect the switching contacts fuse circuit with T 2.5 A or according

to TRD regulations (1.0 A for 72 h operation).

■

The screen must not make any other electrical contact.

Note

■

Connect screen only to terminal [11] and [14] (TRS 5-7b) or terminal

A18 and C18 (TRS 5-7c/d) of the temperature switch.

■

The rated voltage is stated on the name plate.

■

When switching off inductive loads, voltage spikes are produced that

may impair the operation of control and measuring systems. Inductive

loads should therefore be provided with commercial arc suppressor

RC combinations, e. g. 0.1 µF/100 Ω.
