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.

	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,
	please 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 tray. Make
	sure that the mechanical loading of the rack is even.
	￿ Make sure that the ambient temperature within 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 information
	indicated on the type plate. Avoid circuit overloading. If neces-
	sary, provide overcurrent protection.
	￿ Ground the rack via an additional ground connection.
Fastening the optional	￿ Unscrew and remove the 2 torx screws (T25) on each side of the central unit
rack mount “ears”	(see left-hand diagram).
	￿ Secure the optional rack mount “ears” U (see “Accessories” on page 108) to
	the sides of the central unit using the previously removed torx screws (see
	right-hand diagram).
