installation, connection, or configuration, please contact an ADS representative.
Installation should be performed only by qualified personnel according to all
statutory standards, regulations, and technical rulings. During installation, refer to all
local regulations regarding electronic equipment.
Protect the FlowShark Pulse power supply separately using a 6-
amp slow-blow fuse and isolate it from other facility parts through
a separate turn-off. For example, consider using an automatic
cut-off.
Successfully complete transmitter and sensor installation before providing the rated
voltage.
All outer circuits, wires, and lines connected to the device must have a minimum
isolation resistance of 250 volts. Voltages exceeding 42 volts DC require an isolation
resistance of at least 500 kOhm.
The cross-sectional dimension of the power supply wires must be 0.03 square inches
(0.75 mm
2
) and in accordance to IEC 227 or IEC 245. The device protection rating is
IP 65.
The maximum allowable switching voltage on the relay contacts must not exceed 250
volts. According to Ex protection, this voltage must be verified if the device’s power
supply will be integrated into the facility’s emergency shutdown procedures.
