Busbar mounting

5.2.1.1

Preparations

Busbar system
The mains infeed for the power output module is connected via a 3-phase busbar system.
These include the following busbar systems:
● Siemens AG, SENTRON 60 mm
● Wöhner GmbH & Co. KG, 60 mm EQUES
Dangerous voltages on the busbar system
Can cause death, serious injury or damage to property
Dangerous voltages can be present on the busbar system.
The busbar system must therefore be isolated and secured against reclosing before work
begins for mounting and connecting the HCS4300 heating control system.
NOTICE
Clockwise rotating field
When connecting the busbar system, make sure that the energy system is connected
clockwise.
Note
Residual current protective device
If a residual current protective device is provided for the busbar system, a residual current
circuit breaker of Type A is sufficient for the HCS4300.
Note
Due to the weight of the POM4320 we recommend mounting a busbar support after three
devices.
