7.0 OPERATING PROCEDURES
7.1 Introduction
Following installation and commissioning by an authorised service engineer, the UPS will operate in
one of the modes described in 6.3 - Modes of Operation. This chapter describes the various proce-
dures available for the operator to intervene with the UPS mode of operation including starting up,
transferring load to bypass and shutting down.
7.2 Startup in Normal Mode
This procedure must be followed when turning on the UPS from a fully powered down condition - i.e.,
where the load is not being initially supplied at all or where supplied by the maintenance bypass
switch. It is assumed that the installation is complete, the system has been commissioned by autho-
rized personnel and the external power isolators are closed.
