1.6) Safe Installation
Detailed wiring instructions can be found in section 3. The purpose of this section is to reinforce critical safety information.
Prolonged exposure to, or immersion in water exceeds the SA380-IT Ingress-Protection rating. Under such conditions
dielectric withstand voltages cannot be guaranteed.
Never install or energise an SA380-IT that appears to be either physically damaged or suffering from water ingress.
Never connect the SA380-IT directly to monitored circuits without:
Using the approved resistive cable (MPEC part No. SA380-IT-RC).
Connecting via the BX HI Z and NX HI Z terminals.
Never attempt to "common together" any conductors from differing monitored circuits.
Always check the voltage of the monitored and supply circuits:
Check each monitored or supply circuit does not exceed the specified maximum system voltage (160V RMS
). AC/DC
Ensure wiring of monitored or supply circuits is performed such that the cabling is not "live" until installation is
complete.
Attempting any of the above poses a risk of:
Circumvention if the inter-isolation of monitored circuits.
Short circuit of individual monitored circuits.
Electric shock.
The Functional Earth and Loop Earth must be connected to suitable earthing points using separate wires.
It acceptable to use a common earthing point if provision of a secondary earthing point is prohibitive. is
It acceptable to simply strap Functional Earth to Loop Earth. is not
