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 [10] of the temperature switch.
■ The loop resistance must be lower than 10
Ω
.
■ 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
.
