W A R N I N G

Electrocution hazard. Install a 10 A circuit breaker for mains power. Identify the circuit breaker with a

label, as a local disconnect for this equipment.

N O T I C E

Use wire and wiring practices that conform to local, state and national electrical codes. For wet locations, install

the power with a GFIC outlet.

Make all power connections through the conduit opening (Figure 1 on page 7). To maintain the IEC

529 IP62 environmental rating, use liquid-tight sealing-type conduit fittings and cord strain reliefs. If

connections are not made through a conduit opening, install an oil-tight seal in place of the plugs

(Figure 9 on page 14).

Electrical and instrumentation standards require a local method to remove power from the

instrument. The instrument has a power on/off switch that can be accessed without the use of a tool.

An external switch is not required for instrument power. To remove relay power from the instrument,

install an external customer-supplied 5-amp fused switch or a 5-amp breaker.

In hard-wired applications, make sure that the power and safety ground service drops for the

instrument are no longer than 6 meters (20 feet). The exception is when metal conduit is used to

shield the AC power wiring. Use 18 to 12 AWG wire.

If power cords are allowed by local electrical codes, and power surges and transients are not a

concern, use a sealing-type strain relief and power cord. The power cord must have three 18-gauge

conductors (which includes a safety ground wire). Refer to Figure 9 on page 14. The length of the

power cord must not be greater than 3 meters (10 feet).
