operation
Preparing the central unit for use
Setting up the central unit on a flat surface or mounting it into a rack
If you want to place the central unit on a flat surface:
̈ Make sure that the air vents are not covered or blocked.
̈ Place the central unit on a flat surface as shown.
If you want to mount the central unit into a 19” rack, the central unit must be
supported and
fixed to the rack using additional components.
Fastening the optional
rack mount “ears”
̈ Unscrew and remove the 2 torx screws (T25) on each side of the central unit
(s
ee left-hand diagram).
̈ Secure the optional rack mount “ears” (see “Accessories” on page 108) to
the sides of the central unit using the pre
v
iously removed torx screws (see
right-hand diagram).
CAUTION Danger of material damage and personal injury when rack
mounting the central unit!
When installing the product in a closed or multi-rack assembly,
plea
se consider that, during operation,
• the ambient temperature within
the rack may drastically
increase,
• high mechanical loading may occur,
• intrinsically harmless leakage currents of the
individual mains
units may accumulate, thereby exceeding the allowable limit
value.
This can cause material damage and
electric shocks.
̈ Always mount the central unit using a suitable rack tra
y. Make
sure that the mechanical loading of the rack is even.
̈ Make sure that the ambient temperature wi
thin the rack does not
exceed the permissible temperature limit specified in the specifi-
cations (see page 109). Ensure sufficient ventilation; if necessary,
provide additional ventilation.
̈ When connecting to the power supply, observe the in
formation
indicated on the type plate. Avoid circuit overloading. If neces-
sary, provide overcurrent protection.
̈ Ground the rack via an additi
ona
l ground connection.
