Figure 2.5 Alarm relay board connections.
The alarm relay board is inverted when installed in the Powershelf lid such that Relay 5 is
on the left when viewed from the rear of the metalwork. The connections are labelled
again on the rear cover. Each alarm is user programmable through the MiniCSU-3 using
the WinCSU-2 PC software.
