The operator must use suitable measures (e.g. current limiter, fuse) to ensure the following characteristics for
the fail-safe contact and alarm relay are not exceeded:
• U
≤
230 V AC, 50/60 Hz , I
≤
2.5 A,
P
≤
600 VA at cos
ϕ
= 1.0 or P
≤
300 VA at cos
ϕ ≥
0.7 or
• U
≤
120 V DC, I
≤
2.5 A, P
≤
75 W
