General safety instructions
Recognised codes of engineering practice, especially the safety requirements and accident prevention regulations must be
observed when performing all assembly, wiring and commissioning procedures.
Only specially trained and qualified personnel are permitted to perform the assembly, wiring and commissioning.
The electrical installations must be implemented in compliance with the current valid EN / VDE / DIN and local electrical
regulations.
Danger:
Electric shock by touching live parts.
Electrical devices may cause electrical hazards during operation
Before installation/assembly works begin:
Disconnect all poles or switch off supply voltage of TROX UNIVERSAL controller.
Protect power supply against unauthorised or unintended restart.
All installation operations may only start after these safety operations.
