Prior to shipment, every unit undergoes the following tests in order to
isolate any defective units which might suffer an early failure:
• Run-in / burn-in (Full load, T
amb
= +60°C, on/off cycle)
• Functional test (100 %)
X Construction, Mechanics, Installation
Robust plastic housing (US Patent No. D442, 923S), fine ventilation grid
on three housing sides to keep out small parts (e.g. screws), IP20

Ventilation/Cooling
• Free space f. cooling
Normal convection, no fan required
recom'd.: 25 mm on sides with ventilation grid
Easy snap-on mounting onto the DIN-rail (TS35/7,5 or TS35/15).
Unit sits safely and firmly on the rail; no tools required even to remove
Connection by Spring Clamp terminals; uniformly firm hold,
vibration-resistant and maintenance-free:
2 terminals per output
Connector size range
• flexible cable
• solid cable
• Wire strip length
0.3-2.5mm

Design details – for your advantage:
• All terminals are easy to reach as mounted on the front panel.
• Input and output are strictly apart from each other (input below, out-
put above) and so cannot be mixed up.
• Mounting and connection do not require any screwdriver
→ Easy, quick, durable and reliable installation.

Overload behaviour PULS Overload Design™: No switch-off at
overload/short-circuit, instead: up to 1.9 ⋅ I
rated.
So you need no oversizing to start awkward
loads.
Protection Unit is protected against (also permanent) short-
circuit, overload and open-circuit.
