Prior to shipment, every unit undergoes the following tests in order to

isolate any defective units which might suffer an early failure:

• 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

Dimensions and weight

• W x H x D

• Weight

73 mm x 75 mm x 103 mm (+ DIN rail)

Depth incl. terminals: 98 mm (+ DIN rail)

360 g

Mounting orientation

(cf. ’Output’)

Ventilation/Cooling

• Free space f. cooling

Normal convection, no fan required

recom’d.: 25mm 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

Ferrules admissible

6mm (0.24in) recommended

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.
