Safety Instruction and Application Advice
Safety Instruction and Application Advice 11
2.4 Installation
The drive components are designed for fulfilling the degree of pollution 2 according
to IEC 61800-1 / DIN EN 50178.
X The units can be loaded to their maximum up to a height of 1,000 m M.S.L
(3,281 ft M.S.L.)
X For an operation in areas higher than 1,000 m M.S.L. (3,281 ft M.S.L.) the ca-
pacity must be reduced by 15 % per 1,000 m (3,281 ft.)
X The ambient air must not contain aggressive, electrically conductive or flamma-
ble substances and must not contain any amount of dust.
X The maximum relative humidity is approx. 95 % (no condensation).
X The admissible ambient temperature during operation is b5°C and
+40°C (+41°F and +104°F).
X At temperatures higher than 40°C (104°F) the capacity must be reduced by -1.5
% per 1°C. Annotation: F = C × 9/5+ 32; C = (F- 32) × 5/9
X Make sure that the fans installed in the units have sufficient space to take in and
exhaust the cooling air! In addition pay attention to the direction of air flow
through internally installed fans!
X Do not touch electronic components.
2.5 Electrical Connection
The electrical installation must be carried out according to the relevant electrical
codes (e.g. appropriate wire gauges, fuse protection and connections of ground con-
ductors must be considered).
Recommendations for the installation according to the EMC (e.g. shields, connection
to earth and line installations) can be found in the technical documents of the unit
(only for machine manufacturers). The manufacturer of the system or machine has
to meet the requirements of the legislation regarding the EMC.
X All work at and within the units must only be carried out, when the units are
turned off, the mains supply is cut and the DC bus is completely discharged!
X The mains supply must be protected via an overload release with restricted guid-
ance for each mains phase.
X The mains line should only be connected, when the work is completed!
X Before turning on the unit the first time, make sure that the connected machine
will not have runaway axes!
X After turning off the unit hazardous voltages may still exist for up to 3 minutes in
the power supply (due to capacitors).
X Capacitive loads must not be connected to the output phases of the servo am-
plifiers and frequency converters.
X Prevent cable loops. Therefore, the units must only be connected to earth at the
provided PE connection for the mains supply line and the racks only at the pro-
vided earth screw.
SIEB & MEYER products contain electrostatically sensitive
components that may easily be damaged by improper han-
dling.
The valid rules for prevention of accidents (e.g. VBG 1 and
VBG 4) should be paid attention to, when working at current-
carrying units.
