WARNING
High housing voltage and high leakage current!
Danger to life, risk of injury caused by electric shock or severe injury!
●
Before switch-on and commissioning, ground the components of the
DRn system or connect them to the protective grounding conductors at
the grounding points.
●
Always connect the protective grounding conductors of the DRn system
components permanently to the supply network. The leakage current is
greater than 3.5 mA.
●
Use at least a 10 mm² copper cross-section for the entire route of the
protective grounding conductor.
WARNING
Exposure to magnetic and electro-magnetic fields!
Health hazard for persons with cardiac pacemakers, metal implants and
hearing aids in the immediate vicinity of electric components!
●
Ban the group of persons specified above from entering the following
areas:
–
Areas in which components of the DRn system are mounted, com‐
missioned and operated
–
Areas in which motor parts with permanent solenoids are stored,
repaired or mounted
●
Consult a doctor if the persons specified above have to work in these
areas.
CAUTION
Hot DRn system surfaces!
Risk of burning! Risk of injury!
●
Only touch the surfaces of the DRn system with protective gloves or do
not work on hot surfaces.
During or after the operation, temperatures may rise to values higher
than 60 °C (140 °F), depending on the operating conditions.
●
Allow the DRn system to cool down sufficiently before touching it.
●
Observe the protective measures of the end machine manufacturer.
CAUTION
Slip hazard due to oily surfaces!
Risk of injury!
●
Protect and mark the danger zone.
●
Use an oil binding agent in order to bind the leaked hydraulic fluid.
●
Remove and dispose of the contaminated oil binding agent (see
12 "Environmental protection and disposal " on page 121
●
Wear your protective equipment, such as safety shoes.
