Quick Installation and Startup
Peak inrush is 35.7A at 250VAC supply, lasting approximately 1ms
Inrush for other supply voltages can be estimated with:
Inrush (Amps) = Supply (Volts) / 7.0
Supply wire requirements
Use 10 - 18 AWG wire rated for the proper temperature of the application. For wire 10 - 14 AWG
use lugs or other appropriate connectors. For connections in ambient temperatures above 122
°F (50 °C), use a wire rated for 194 °F (90 °C). For DC powered transmitters with extended cable
lengths, verify that there is a minimum of 12VDC at the terminals of the transmitter with the
device under load.
Electrical disconnect requirements
Connect the device through an external disconnect or circuit breaker per national and local
electrical code.
Installation category
The installation category for the 8732EM is OVERVOLTAGE CAT II.
Overcurrent protection
The 8732EM transmitter requires overcurrent protection of the supply lines. Fuse rating and
compatible fuses are shown in Table 2-12.
