Installation instructions for enhanced mechanical load
capacity

WARNING

Risk of injury through electric shock and damage to the device!

Bring the Bus Terminal system into a safe, de-energized state before starting mounting,
disassembly or wiring of the Bus Terminals!

Additional checks

The terminals have undergone the following additional tests:

Verification

Explanation

Vibration

10 frequency runs in 3 axes

6 Hz < f < 60 Hz displacement 0.35 mm, constant amplitude

60.1 Hz < f < 500 Hz acceleration 5 

g

, constant amplitude

Shocks

1000 shocks in each direction, in 3 axes

25 

g

, 6 ms

Additional installation instructions

For terminals with enhanced mechanical load capacity, the following additional installation instructions apply:

• The enhanced mechanical load capacity is valid for all permissible installation positions

• Use a mounting rail according to EN 60715 TH35-15

• Fix the terminal segment on both sides of the mounting rail with a mechanical fixture, e.g. an earth

terminal or reinforced end clamp

• The maximum total extension of the terminal segment (without coupler) is:

64 terminals (12 mm mounting with) or 32 terminals (24 mm mounting with)

• Avoid deformation, twisting, crushing and bending of the mounting rail during edging and installation of

the rail

• The mounting points of the mounting rail must be set at 5 cm intervals

• Use countersunk head screws to fasten the mounting rail

• The free length between the strain relief and the wire connection should be kept as short as possible. A

distance of approx. 10 cm should be maintained to the cable duct.

Connection system

WARNING

Risk of electric shock and damage of device!

Bring the bus terminal system into a safe, powered down state before starting installation,
disassembly or wiring of the Bus Terminals!

Overview

The Bus Terminal system offers different connection options for optimum adaptation to the respective
application:

• The terminals of ELxxxx and KLxxxx series with standard wiring include electronics and connection

level in a single enclosure.

• The terminals of ESxxxx and KSxxxx series feature a pluggable connection level and enable steady

wiring while replacing.
