3.4 Basic Functional Check
Before starting the system with VME boards the following tests have to be done:
•
Ensure that the unit does not get damaged during tranport.
•
Check the Protective Earth (PE) resistance, should be < 0,1 Ohm.
•
Switch on the system and check all VME voltages on the Backplane
connectors before you plug in the VME boards.
Note:
The +12 V output requires 10% minimum load, i.e. a resistor
12 Ohm / 12 W.
•
Plug in the VME boards.
•
Cover all open Slots with filler panels.
•
Tighten the rear panel mounting screws.
•
Power-on the system and determine the actual current consumtion.
•
Replace the mains fuses suitable to the actual current.

Warning!
Voltages over 60 VDC can be present in this equipment. This equipment is
intended to be accessed, to be installed and maintained by qualified and
trained service personnel only.
This eqipment is designed in accordance with protection class 1!
It must therefore be operated only with protective GND/earth connection!
The fuse value has been determined in factory for the maximum power
delivered by the power supply. The fuse value must be adjusted to the actual
current consumtion of the completed system.
Maximum value is 8 A slow.
