Hydran* M2-X Instruction Manual
MA-029 Rev. 1.0, 30-Jul-18
4.3.10.5 Analog Output Cable (If Used)
Proceed as follows:
1. Run the cable through a conduit, from the Hydran M2-X to the SCADA system.
2. Verify all wires are identified at both ends.
3. Connect the wires to the corresponding I/O terminal block of the Hydran M2-
X. For wiring details, see Section D-3.
4. Connect the other end of the cable to the SCADA system.
4.3.10.6 AC Power Supply Cable
Turn off the electric power power at the switch or
circuit breaker provided for disconnection before
making any electrical connections, and ensure a proper
ground connection is made before connecting the
power supply. Failure to do so can result in property
damage, personal injury and/or death.
Note: The external ac power supply range is 110 Vac ± 15 % or 230 Vac ± 15 %, and
from 47 to 63 Hz.
Proceed as follows:
1. Run the cable through a conduit, from the Hydran M2-X to the power source.
The first temporary plug (see item 1 in Figure 2-6 must be
removed and replaced with a watertight fitting to connect
the ac power supply cable.
2. Remove the plastic cover from the ac power supply terminal block.
3. Connect the wires to the ac power supply terminal block of the Hydran M2-X.
For wiring details, see Section D-7.
4. Connect the other end of the cable to the power source. An external circuit
breaker must be installed on the ac source and labeled accordingly,
complying with the applicable regulations.
Note: Fuses or an external circuit breaker must be installed and duly identified near
the Hydran M2-X, in accordance with the IEC* 947-1 and 947-3 standards, the local
building codes or the current edition of the National Electrical Code.
5. Power up the Hydran M2-X.
6. Verify the display is lit.
Note: The earth/ground terminal (E/G) must be connected to the power source ground
(green wire) or directly to the transformer tank. For special considerations regarding
grounding, see the note at the beginning of Section 4.3.8.
Never perform high-voltage tests (mega-ohm measurements
using a Megger instrument) on cables connected to a Hydran
M2-X. Never apply high voltages to the Hydran M2-X
terminals, as they are equipped with surge protection
devices that could be damaged by Megger tests.
