11/17 Operating Instructions AEC 15
2.11.5 Electrical connections
 The five safety rules must be complied with.
 Never touch live terminals. The DC-link may have dangerous voltage levels even up to 8 minutes after
shutdown.
 When performing any work on/with the AEC, always comply with the applicable national and
international regulations/laws on work on electrical equipment/plants of the country in which the AEC
is used.
 The cables connected to the AEC may not be subjected to high-voltage insulation tests unless
appropriate circuitry measures are taken before.
 Only connect the AEC to suitable supply mains.
2.11.6 The five safety rules
When working on/in electrical plants, always follow the five safety rules:
1. Isolate
2. Secure to prevent restarting
3. Check isolation
4. Earth and short-circuit
5. Cover or shield neighboring live parts
2.11.7 Safe operation
 During operation of the AEC, always comply with the applicable national and international
regulations/laws on work on electrical equipment/plants.
 Before commissioning and the start of the operation, make sure to fix all covers and check the
terminals. Check the additional monitoring and protective devices according to the applicable national
and international safety directives.
 During operation, never open the machine/plant.
 Do not connect/disconnect any components/equipment during operation.
 The machine/plant holds high voltage levels during operation, is equipped with rotating parts (fan)
and has hot surfaces. Any unauthorized removal of covers, improper use, wrong installation or
operation may result in serious injuries or material damage.
 Some components, e.g. the heat sink or braking resistor, may be hot even some time after the
machine/plant was shut down. Do not touch any surfaces directly after shutdown. Wear safety gloves
where necessary.

The device may hold dangerous voltage levels until the capacitor in the DC link is discharged. After
shutdown, wait for at least 3 minutes (device sizes 3 through 7) and at least 8 minutes (device size 8)
before starting any electrical or mechanical work on the AEC. Even after this waiting time, make sure
that the equipment is deenergized in accordance with the safety rules before starting the work.
 In order to avoid accidents or damage, only qualified staff and electricians may carry out the work
such as installation, commissioning or setup.
 In the case of a defect of terminals and/or cables, immediately disconnect the device from power
supply.
 Persons not familiar with the operation of AECs must not have access to the device. Do not bypass
nor decommission any protective devices.
 Devices (sizes 3 through 7) disconnected from mains supply may only be reconnected after 60s.
Devices of size 8 my only be reconnected after 8 minutes. This must be considered when operating a
mains contactor in jog operation mode. For commissioning or after an emergency stop, a non-
recurrent, direct restart is permissible.

Before commissioning and the start of the operation, make sure to fix all covers and check the
terminals. Check the additional monitoring and protective devices according to EN 60204 and
applicable the safety directives (e.g. Working Machines Act or Accident Prevention Directives).
