1) • The rated tightening torques for fasteners without
lubrication are based on a coefficient of friction for the
thread of 0.14 (the actual values are subject to an
unavoidable, partly not inconsiderable, spread).
• Rated tightening torques for fasteners with lubrication in
accordance with DIN 43 673.
2)
Thread and head contact surface lubricated.
Any tightening torques which deviate from those in the general
table (e.g. for contact systems or device terminals) are to be
taken into account as stated in the detailed technical
documentation. It is recommended that the threads and head
contact surfaces of the bolts should be lightly oiled or greased,
so as to achieve a precise rated tightening torque.
Commissioning / Operation

6.1 Notes on safety at work
• Operation is only permissible by specially trained
personnel who
characteristics of the particular switching device.
• Observe the relevant specifications as set out in
section 1.2.
• The discharge energy of the storage capacitor
is greater than 350 mJ. The procedure for
discharge of the storage capacitor as set out in
section 7.1 is to be observed.
6.2

Preparatory activities

(before connecting the primary voltage)
• Check the circuit-breaker, withdrawable part,
contact arms, insulating parts etc. for damage,
and restore to their proper condition if
necessary.
• Remove any dirt collected during transport,
storage or installation (particularly on the
insulating materials) as described in section
7.3.1.
• Remove lifting lugs T (Figures 10/3, 10/4, 10/5,
10/8, 10/9 and 10/12).
• Check the primary and secondary connections
and the protective earth conductor connection.
• Check the connection of the main earthing bar
with the station earthing conductor (DIN VDE
0141).
• Remove all material residues, foreign bodies and
tools from the switchgear.

• Properly refit all covers, etc., removed during
assembly and testing processes.
• Connect the supply voltage (Figures 10/6 and
10/14 to 10/17). Input -Y4
(closed-circuit shunt release) and input -Y1:
"Closing lock-out" (closed-circuit shunt release)
must be supplied with power before the circuit-
breaker can be closed.

• For this reason, an internal circuit applies a
voltage of 80 V to these inputs as soon as the
,5
storage capacitor is charged in as-delivered
,5
condition of devices with no connector wiring.
• If these shunt releases are used to monitor a
,5
voltage, the voltage to be monitored is to be
,5
applied to these inputs (see also section 4.4.1).
• Should the voltage fail at shunt release -Y1,
closing is impossible.
• Should the voltage fail at shunt release -Y4
breaker opens.
• Storage capacitor 26:
In the case of a (voltage-free) storage period of
more than 2 years, an increased current
consumption, which is nevertheless below 2 A,
occurs
commissioning as a result of reforming.
• Check mechanical and electrical interlocks for
effectiveness, without using force.
• Perform test closing and opening of the circuit-
breaker by pressing push-buttons 3 and 4
(see Figure 9/19).
• On motor-driven withdrawable parts, check the
direction of rotation of the travel motors as
the
described in section 7.5.3.
• For any further questions on the functions of the
withdrawable circuit-breaker part and its testing,
see section 7.5.
• Instruct the local operators in the fundamental
details of regular handling of the switchgear.

Movement of the withdrawable breaker part

(Figures 9/12, 9/19 and 9/23 to 9/25)
Perform switching operations with the front doors
shut.
6.3.1 Manual insertion from the test/disconnected
position to the service position
• Connect control wiring plug 36.1.
• Close the front door.
• Ensure that the circuit-breaker is in the OFF
position.
• Fit hand crank 38 on square spigot 35.2 of the
spindle mechanism 35.1.
