Operating the Device
19 Chloride Linear Plus Series Rack-mount UPS User Instruction Manual
Emergency Power
Off (ESD hardwired)
This Linear Plus Rack-mount UPS is equipped with separate terminals for connecting hardwired customer
protection ESD relays. See block diagram Fig. 7 on page 14 for connection details.
Paralleling UPS
Devices
A maximum of 3 Linear Plus Rack-mount UPSs can be connected in parallel. The units to be connected
in parallel must be of the same type and rating and the settings of these devices must be identical.
The units configured as a parallel system may use only common mains supply.
Designing a Parallel
System
When connecting mains and loads to a parallel UPS Linear Plus Rack-mount system additional
distribution has to be taken into account.
A system of 2 parallel UPS blocks can be connected directly to the distribution if the system load doesn’t
exceed the nominal power of the UPS block (configuration: half load, 2 block parallel system)
If the supported load is greater than 50% of the total paralleled UPS load, it is suggested that an external
maintenance bypass be installed.
