Warning: Never insert a EQ1 unit while your rack is powered.
It may cause damage to the unit as well as the rack.
EQ1 must not be operated at ambient temperatures above 40°C and below 5°C.
As API series racks are equipped individually and the cabinets they are mounted in differ a lot in the way they are
ventilated, there is no rule other than keeping an eye on the temperature inside the rack while in operation.
Operating a unit beyond the limits can lead to severe damage.
In case you need to remove EQ1 from an API 500 series rack, you may use a gadget on the front panel: Remove the
M3 countersunk screw in the LO MID section. In place of this screw, screw in the enclosed knurled head screw with
M3 thread, gently without using any force. Then seize the tool and draw out the unit from the rack. Just draw on the
tool, do not apply any force to the sides! Do not forget to unscrew the bolt and remount the M3 countersunk screw.
