4.1 Checklist for commissioning
Before commissioning the DS7 soft starter, make sure to check the
following (using the check list):
No. Activity Note
1 Installation and wiring completed as specified in the relevant
instructional leaflets (￫ table 3, page 18) and this manual.
2 All wiring and line section leftovers, as well as all the tools used,
have been removed from the soft starter’s and the drive motor’s
proximity.
3 All terminals in the power section and in the control section
were tightened with the specified torque.
4 The lines connected to the output terminals of the soft starter
(2/T1, 4/T2, 6/T3) are not short-circuited and are not connected
to ground (PE).
5 The heat sink (in size 3 and 4 soft starters) is properly earthed
(PE).
6 All electrical connections and switchgears in the power section
were implemented properly and were designed in line with the
corresponding requirements.
7 Each single phase of the supply voltage (L1, L2, L3) is protected
with a fuse.
8 Soft starter and motor are adapted to the mains voltage
(i.e. the
rated operational data on the nameplate and the “star” and
“delta” connection have been checked).
9 The quality and volume of cooling air are in line with the
environmental conditions required for the soft starter and the
motor.
10 All connected control cables comply with the corresponding stop
conditions (e.g., switch in OFF position).
12 The effective direction of a coupled machine will allow the motor
to start.
13 All emergency switching off functions and safety functions are
in an appropriate condition.
