4.3 Power Wiring Considerations

Recommended wire size

Observe all applicable electrical codes when making power connections. Unless locally applicable codes dictate otherwise, use 14-gauge (2.081 mm2) wire for ac power, including protective earth.

Power supply voltage and frequency within specs

The power supply voltage and frequency must be within the limits stated in the specifications in Section 2.

4.4 Installing Power Wiring

Procedure

WARNING

Turn power off at mains before installing AC Power Wiring.

Do not remove boards with power ON.

WARNING

The ground terminal must be connected to a reliable earth ground for proper operation and to comply with OSHA and other safety codes. If metal conduit is used, connect a bonding wire between conduits. Do not rely upon the conductive coating of the instrument case to provide this connection. Failure to observe this precaution may result in serious personal injury.

CAUTION

To avoid damage to the case when connecting to a rigid metallic conduit system, the conduit hub must be connected to the conduit before the hub is connected to the enclosure
