Attention

■

Fuse supply cable with T 2.5 mA.

■

When switching off inductive loads, voltage spikes are produced

that may impair the operation of control and measuring systems.

Inductive loads should be provided with commercial arc suppressor

RC combinations, e. g. 0.1 µF/100 Ω.

Note

Connect only volt-free relay contacts to the control inputs. The cycling

timer PRS 9 supplies a 12 V DC control voltage.
