Supply power requirements
Observe the general requirements related to the supply power.
The supply voltage to the MS70 must be kept within ±10% of the installation's nominal
voltage. Maximum transient voltage variations on the main switchboard's bus-bars are not
to exceed -15% to +20% of the nominal voltage (except under fault conditions).
Uninterruptible Power Supply (UPS) requirements
Observe these requirements related to the Uninterruptible Power Supply (UPS).
We recommend that the MS70 system is powered using an Uninterruptible Power Supply
(UPS) with sine wave output.
The Uninterruptible Power Supply (UPS) must have the capacity to independently maintain
power to the MS70 for a minimum of 10 minutes. This ensures that the MS70 can be turned
off in a controlled manner in the event of a power failure.
Cables and wiring requirements
Correct wiring is crucial for the operational performance of the MS70.
All cables running between system cabinets located in different rooms and/or on different
decks must be supported and protected along their entire lengths using conduits and/or cable
trays. Note that the cables must not be installed in the vicinity of high-power supplies and
cables, antenna cables or other possible sources of interference.
