UPS: MKD 700
– 3000 VA RT (XL)
Installation and Connection
It is implicit to connect the protective conductor here and to maintain the loop
resistance all the way to the last load.
It is likewise possible to secure the loads separately against over and fault
currents and to directly ground them.
Always pay attention to the correct polarity (L, N) between input and output for
the UPS.
If the UPS is in the midst of an emergency stop circuit, it must be observed that
the UPS output is not completely currentless after the emergency stop circuit
operation. The loads will continue to be supplied for the duration of the UPS
autonomy time.
Components of the UPS device carry high voltage and current strength.
Improper use can thus result in electrical accidents with fatal outcomes or cause
property damage.
5.4.1
Connection to the external battery bank
The battery bank for this device series usually employs the required connection
cable for the coupling. An extension of this connection is not intended.
Furthermore, these battery banks are equipped with an additional parallel
connection (DC) in order to apply several external battery banks until the
desired capacity (or autonomous time) has been reached.
The MKD
Standard
is suitable for a maximum of 2 battery strings for coupling
the UPS with external battery banks and the MKD
XL variants
is suitable for
more than 2 battery strings because this commands a powerful charging unit.
Always ensure that the connection data of both devices (battery bank and UPS)
conform to each other.
The external battery bank connection is completed in a few steps with the
quality equipment of the MKD devices (PLUG AND PLAY). Follow the preceding
description for this.
