Unused contact points under voltage
Protect unused contact points that may live against
inadvertent touching using suitable covers, such as
ADP The clamping screws unused contact points
that are not live must also tightened.
Working electrical connectors with non-insulated
screwdrivers
The following five rules apply for working electrical
systems and equipment with non-insulated screwdrivers:
• Disconnect the electrical systems
• Prevent from being switched back on
• Ascertain absence voltage
• Earth and short-circuit
• Cover block off neighbouring parts under voltage
Please find the individual measures taken consideration
of the operational and local conditions, for example high
voltage and low voltage lines, cables switchgear systems, in
VDE 0105 Part 100.g.

We specify the required stripping length for all our products

Tightening torque range for clamping screws
The test torque according IEC 60947-1 the torque
according the manufacturer‘s specifications the lower

± are absolutely binding. These lengths, e. This also the case you
use wire-end ferrules.
Tightening the clamping screw the specified torque
ranges ensures:
• Reliable and gas-tight clamping
• mechanical destruction the clamping yokes
• Voltage drop well below the required limit value
Our installation tips for you
• The terminal strip structure from left right
• Place the closed side the left, the open side to
the right
• Always close the open side the terminal strip
with end plates separation plates
(WAP/TW, ZAP/TW)
• End brackets have placed the beginning
and end terminal strip
C. IEC 60947-1 applies for the outside
dimension crimped wire-end ferrules
