1.8. Safety and Installation instructions
The ERS is a device intended for use in industrial high-voltage plants and is operated with voltages
that can cause serious injuries or death when touching!
•
Installation and other work may only be carried out by qualified specialist electricians and at a
voltage free device. The user manual must always be available to them at any time and has
to be consequently regarded.
•
Local regulations for the installation of electrical systems and accident prevention regulations
must be observed.
•
The device continues to carry current in the ERS, after switching off the mains at the
frequency inverter or servo controller, for up to 5 minutes dangerous voltage. Opening the
device is therefore only permitted until 5 minutes after the unit is completely free of voltage.
Before switching on the supply voltage all covers have to be reattached.
•
Also at motor standstill (e.g. due to electronics lock, short circuit at the output clamps
or blocked drive) the voltage circuit clamps, motor clamps and clamps for the brake
resistance may conduct dangerous voltage. A motor standstill is not identical with
a galvanic disconnection from the mains voltage.
•
Attention: The ERS may after the mains are switched on, depending on the settings,
start automatically the regenerative mode.
Attention! Danger to Life!
The power supply conducts voltage under certain circumstances for up to 5 minutes
after turning off the mains voltage. Terminals, DC lines and network terminals may be
alive!
Touching open or free terminals, cables and device parts may cause serious injuries
or death!
Attention
•
Children and the public must not have access to the device!
•
The device may only be used for the purpose intended by the manufacturer. Unauthorized
changes and the use of replacement parts and additional devices that are not sold or
approved by the manufacturer may cause fire, electric shocks and injuries.
•
Keep the manual in reach and make it available for every user!
European EMC directive
IF a frequency inverter is installed in conjunction with an ERS as recommended by this manual, it will
meet the requirements of the EMC Directive, in accordance with the EMC product standard for motor-
operated systems EN 61800-3, provided it was previously fulfilled by the frequency inverter.
