•
To reduce static build-up, avoid excessive movement. Transport static-
sensitive components in anti-static containers or packaging.
•
To discharge static electricity from your body and keep it discharged, wear a
wrist strap connected by a wire to earth ground.
•
Handle all static-sensitive components in a static-safe area. Use anti-static
floor pads and work bench pads.
Use a 3-wire, single-phase power supply with an appropriate cross-section for
the required power. Connect to the instrument power terminal as follows:
1. Remotely disconnect instrument power before opening the analyzer door.
2. Remove the four screws from the front cover. Open the cover. Remove the
internal shielding plate (4.4.3).
3. Strip the outside insulation of each wire back ¼-inch
4. Route the wires or approved power cord through the back right conduit
opening. Use the provided cord-connected strain reliefs to ensure adequate
sealing. Use appropriate NEMA sealing hardware
5. Using the connection diagram on the shield plate, insert the wire ends into the
mains connector until the insulation seats against the connector
6. Tighten the connectors using a small flat-head screwdriver. Firmly tug each
wire to ensure solid connections.
7. Reinstall the shielding plate and front cover if all of the wiring is complete.
