4.6 AC Input Connection
WARNING
Ensure that mains input is turned off before connecting. The grounding must
be connected to PE terminal as first.
WARNING
High leakage current. Ensure earth is connected before connecting mains
supply.
CAUTION
Depending on deployment region with regards to lightning strikes and heavy
inductive energy, it is highly recommended to install AC Surge Protection Class C, if not
delivered with the system..
WARNING
Used cable must be inserted into the terminal with as little insulation removed
as possible, so as to prevents any stranded conductor coming loose and touching any other
conductive parts. Tighten terminals securely with torque 1.5-1.8Nm.
To connect, route the AC input cable through the cable entry and connect to the AC terminals.
