6 Installation and removal
When installing or removing the LIQ-60, if using a hot stick, use only a hot stick rated for use
at or above the voltage of the conductor on which the LIQ-60 is inst alle d.
Similarly, if using the glove and barrier method, ensure that the safety equipment used is
rated at or above the voltage of the conductor on which the LIQ-60 is i n s t a l l e d .
6.1 LIQ-60 installation
The LIQ-60 has been designed for live line installation on Medium and High Voltage (MV and HV) networks
(up to 138 kV) using an electric utility hot stick, or using a glove and barrier method with a live line crew.
These instructions apply to installation using a hot stick. Each LIQ-60 takes just a few minutes to install.
6.1.1 Pre-installation
Prior to mounting, set the orientation of the LIQ-
60’s solar panel to maximize sunlight falling onto it. See
section
7.2 Solar Panels
for details on determining the direction and angle at which to mount the solar
panel.
6.1.2 Mounting
1. Ensure that the LIQ-60 is switched on and configured.
2. Rotate the solar panel so that once the LIQ-60 is in position, it will receive the most sunlight, i.e.
facing north when in the southern hemisphere, and south when in the northern hemisphere.
3. Adjust the angle (elevation) of the solar panel as discussed in section
7.2 Solar Panels.
4. Clamp a hot stick hook onto the sprung slider and pull the hook and slider into the head of the
hot stick. This opens the LIQ-
60’s conductor clamp and the sensing coil.
5. Ensure the LIQ-60 is firmly secured to the hot stick.
6. Install the LIQ-60 by hooking the top portion of its housing over the conductor, so that the
channel in the LIQ-
60’s housing encompasses the conductor.
7. Release the hot stick so that the sprung clamp and sensing coil close, thereby clamping the LIQ-
60 to the conductor.
8. Take note of the reference arrow on the bottom of the LIQ-60, and in which compass direction
this points, e.g. north, north west etc. This is required to identify the direction of line faults when
they occur.
9. Please do not mount the CMS on an insulated conductor
6.1.3 Post-installation checks
1. Check that the LIQ-60 is hanging vertically and has clamped securely onto the conductor.
2. Check that the solar panel direction will maximize exposure to sunlight.
3. Check that the status LEDs are showing correct status: both red LEDs flashing every second
(and a status amber flash every 30 sec) if not yet commissioned, or an amber flash every 30 sec
when commissioned and reading voltages and current.
