NOTICE
Failure and damage of product and system by interrupting the supply voltage
If the supply voltage of the product is interrupted during operation or a firmware update, a
failure of the product or the entire system may occur. This may result in loss of external setpoints
and a non-permitted starting behavior of the system. In addition, the device can be irreversibly
damaged.
• Ensure that the supply voltage of the product is never interrupted during operation. To do
this, use an uninterruptible power supply with 7 minutes bridging time.
Electrical installations (for North America)
All installations must conform with the laws, regulations, codes and standards applicable in the
jurisdiction of installation (e.g. National Electrical Code
®
ANSI/NFPA 70 or Canadian
Electrical Code
®
CSA-C22.1.).
• Before connecting the product to the utility grid, contact your local grid operator. The
electrical connection of the product must be carried out by qualified persons only.
• Ensure that the cables or conductors used for electrical connection are not damaged.
IP addresses of Modbus devices
In systems with Modbus devices, static IP addresses must be assigned to all Modbus devices.
Suitable IP addresses can be assigned to the Modbus devices from the free address supply of
the network segment either manually or dynamically via DHCP.
If the IP addresses are to be assigned dynamically, DHCP must be activated in the router (see
the router manual). Make sure that the Modbus devices do not contain variable IP addresses
but always the same IP addresses.
IP addresses in local networks
In local networks where no DHCP server is active, proper IP addresses must be assigned from
the free address pool of the network segment to all network participants to be integrated
during commissioning.
If the IP addresses in the local network are to be assigned dynamically, DHCP must be
activated in the router (see the router manual). The DCHP server automatically assigns the
appropriate network settings to your nodes in the local network. A manual network
configuration is therefore not necessary.
