5 Electrical installation
Danger!
It is forbidden to carry out work on electrically live parts.
Even after disconnection, the DC-link ( terminals X1: +DC / X1:-DC ) are still live.
Wait at least 3 minutes before working on the device
Danger!
Operating the ZETADYN 3C with the housing cover removed is prohibited because energized,
exposed parts are present inside the device. Disregarding this regulation can lead to severe personal
injury.
Work on electric components may only be carried out by trained electricians or by persons instructed
in electricity under the supervision of an electrician in accordance with electrical engineering regula-
tions.
A second person must always be present when working on energized parts or lines who disconnects
in case of emergency.
Inspect electrical equipment periodically: retighten loose connections
–
immediately replace damaged
lines and cables.
Always keep switch cabinets and all electrical supply facilities locked. Access is only allowed for
authorized persons using a key or special tool.
Never clean electrical equipment with water or similar liquids.
5.1 EMC-compatible installation
When correctly installed (see below), the device corresponds to the following standards:
• EN 12015 Electromagnetic compatibility
–
product series standard for lifts, escalators, moving
pavements
–
spurious emission
•
EN 12016 Electromagnetic compatibility
–
product series standard for lifts, escalators, moving
pavements
–
interference immunity
The following points must be observed if the above mentioned standards are to be adhered to:
• Use only shielded cables for motor and brake chopper or brake resister connections.
• Max. motor line length is 25m
• Wind unshielded cables of brake resistors type BR09-1 and BR11-A around the toroidal core
provided (see
fi
gure)
•
If you must interrupt the shielding on a cable (e.g., to install a motor contactor), the shielding must
be subsequently continued with the lowest possible HF impedance.
• Use only shielded control cables
• The shielding of control cables (inputs and outputs, rotary encoder cable, etc.) must be connected
to earth potential on the inverter side
• The shielding of control cables (inputs and outputs, rotary encoder cable, etc.) must be connected
to earth potential on the inverter side
•
Use shielded lines in the switching cabinet also
•
Do not twist shielding for connections; use a suitable shield connection system
•
Run the control cables and the encoder cables separate from the power cables
• Provide connected inductances (brakes, motor contactors) with suppressors
• Feed the power supply of the motor contactors through the mains

Information
Please contact the manufacturer for information on adhering to the limit value class B in accordance
with EN 55011.
