2.4.1.2 Internal control UPS (option)
A battery-based UPS (Uninterruptible Power Supply) is available as an
option, increasing the control buffer time to 15 minutes after loss of control
power. In the event of a control power outage, communication to a higher-
level control system will not be lost.
Monitoring of battery health is provided. The battery is located at the
bottom of the swing frame to allow for easy replacement.
To prolong battery life when drive control power is shut down, switch the
battery control module to the “service” setting. When control power is
restored, the battery control module should be switched back to the
“12A-h” setting.
2.4.1.3 Converter space heater (option)
When the converter space heater is installed on the drive, an additional
120 V power supply cable is required. This control supply is wired to
terminal block X20 as illustrated in Figure 2-17.
