OPENING THE CHASSIS
If the DX4500/DX4600 is mounted in a rack, it must be removed from the rack prior to HDD installation. 
One person can lift and remove the DVR. 
Make sure the unit is turned off and you are wearing a properly grounded ESD wrist strap before 
attempting to open the chassis cover. 
1. Ensure that the DVR and all of its components are protected against ESD. Before handling any 
electronic components, you should take steps to ground yourself properly so that any built-up static 
electric charges are dissipated away from the unit. 
a.
Cover all work areas with approved anti-static mats (supplied).
b.
Attach the disposable wrist strap (supplied). Refer to Figure 5 and the included Safe Handling 
of Hard Drives instructions (C2668M) for proper ESD procedures.
c.
Attach the copper end of the wrist strap to an upainted surface of any grounded appliance. 
An appliance is considered grounded if it can direct ESD to the earth, usually through its 
power cable. An appliance that is plugged into an electrical outlet is considered grounded; a 
unit is not considered grounded when it is unplugged.
WARNINGS:
Do not touch the circuit board with your hand or a tool. Hold the HDD by the sides only.
Do not wear grounding straps over clothing as clothing generates static electricity.
