Uninterruptible Power Supply (UPS)
Overview
The Uninterruptible Power Supply (UPS) option is only available for PS-B. The
following figure shows a PS-B equipped with the UPS option:
1 UPS battery unit
2 UPS connection cable 3 m (9.84 ft)
3 PS-B with UPS Interface Board (pre-installed)
NOTE:
When using a model with an integrated UPS module, connect the UPS battery unit
before starting up the PS-B. If the PS-B is started before the UPS battery unit is
connected, a system error will occur and the buzzer will sound, so please use
caution.
The main features of the UPS option are:
z Long-lasting, maintenance-free rechargeable batteries
z Communication via integrated interfaces
z Temperature sensor
z Deep discharge protection
UPS Principle
With the optionally integrated UPS, the PS-B system completes write operations
even after a power loss. When the UPS detects a power loss, it switches to battery
operation immediately without interruption. This means that all running programs
are ended properly by the UPS software. This prevents the possibility of inconsistent
data.
NOTE:
z This function is only available if the UPS is configured and its driver is activated
(see page 122).
z The monitor is not handled by the UPS and will shut off when the power fails.
