Connecting the supply voltage
Note: For redundant and outfall-resistant power supply, you can connect
multiple power sources in any combination at the same time. The device
automatically selects the power supply. If the power supply currently active
is interrupted and another power supply takes over the supply of power to the
device, the device may reboot in order to reactivate the power supply.
2.11.1 5-pin M12 connector (BAT-F)
A 5-pin M12 connector (A coding, supplied) is used to connect the power
supply.
On delivery, the connectors are sealed with cover caps.
The housing of the M12 frame connector is electrically connected to the
functional ground (FE) and to the metal housing of the device. The supply
voltage is electrically isolated from the housing.
Note: For the BAT54-F, the voltage supply is exclusively via PoE
(see
page 43 „Power over Ethernet (PoE) - power supply via the LAN cable“)
.
2.11.2 4-pin terminal block (BAT-Rail)
The supply voltage is connected via a 4-pin terminal block with a snap lock.
The supply voltage can be connected redundantly. Both inputs are
uncoupled. There is no distributed load. With redundant supply, the power
supply unit supplies the device only with the higher output voltage. The
supply voltage is electrically isolated from the housing.
