Electrical installation
Danger!
It is forbidden to carry out work on electrically live ZArec4C.
Even after disconnection, the DC-link ( terminals X2: +DC / X2: -DC ) are still live.
Wait at least 3 minutes before working on the device
Danger!
It is not permitted to operate the ZArec4C with the housing covers removed, as exposed live parts are
present inside the ZArec4C. Failure to observe this provision can lead to serious injury.
Warning!
Parts can be destroyed by electrostatic discharge.
Discharge yourself by suitable action before working on electrical components (connectors, etc.). You can do this,
for example, by touching earthed metal parts.
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.
Electrical equipment must be checked regularly: Loose connections are to be re-tightened and
damaged lines or cables must be replaced immediately.
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 ZArec4C corresponds to the following standards:
•
EN 12015:2004 Electromagnetic compatibility
–
Product family standard for lifts, escalators and
moving walks
–
Emission
•
EN 12016:2004 + A1:2008 Electromagnetic compatibility
–
Product family standard for lifts, escala-
tors and moving walks
–
Immunity
The following points must be observed if the above mentioned standards are to be adhered to:
•
Only use shielded cables for connecting the intermediate circuit
•
Wind unshielded cables of the brake resistor type BR14-A around the included toroidal core (see
fi
gure in the chapter "Electrical Installation / External Brake Resistor (X-BR)")
•
If an interruption in the shield is necessary, the shield must then be continued with as low an HF
impedance as possible
•
Use only shielded control cables
•
The shielding of power cables (brake resistance cable, DC cable) must be connected to ground on
both sides
•
The shielding of control cables (input and outputs) must be connected to ground 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 (contactors) with suppressors
