APPENDIX E/ Common Circuit Connections
WARNING
To avoid the risk of electric shock or burns, always connect the safety (or earth)
ground before making any other connections.
WARNING
To reduce the risk of fire, electrical shock, or physical injury it is strongly
recommended to fuse the voltage measurement inputs.
Fuses must be located as close to the load as possible to maximize protection.
WARNING
For continued protection against risk of fire or shock hazard replace only with
same type and rating of recommended fuse.
Use only fast blow type fuse which is rated 600V. Recommended fuse type is
Littelfuse, part number KLKD.300 rated 600V AC/DC, 0.3A fast blow.
WARNING
Do not replace fuse again if failure is repeated. Repeated failure indicates a
defective condition that will not clear with replacement of the fuse. Refer
condition to a qualified technician.
Safety
precautions
The following safety precautions must be followed whenever any type of voltage or
current connection is being made to the 4400.
• Wear proper Personal Protective Equipment, including safety glasses and insulated
gloves when making connections to power circuits.
• Hands, shoes and floor must be dry when making any connection to a power line.
• Before each use, inspect all cables for breaks or cracks in the insulation. Replace
immediately if defective.
• Set the 4400 power switch to Off.
• Before connecting to electric circuits to be monitored, open their related circuit
breakers or disconnects. DO NOT install any connection of the 4400 to live power
lines.
• Connections must be made to the 4400 first, then connect to the circuit to be
monitored.
