7.2.1 Remote shutdown
The REMOTE SHUT DOWN must use a normally closed contact, which opens to operate the remote
shut down sequence.
The remote shutdown on terminal port X1/7.. X1/8 is located at the bottom of the DPA UPSCALE
TM
frame on communication card with terminal blocks X. See chapter 6.4.3 for details.
In order to allow removal, maintenance or testing of any remote shut down facility without disturbing
the normal operation of the UPS, it is recommended that a terminal block, with linking facilities, be
installed between the UPS and the stop button.
1. Use a screened cable with 1 pair (section of wires 0.5 mm
2
) and maximum length of 100 m.
2. Connect the cable as shown in Fig. 7.2.1-1

7.2.2 Generator ON facilities
The Generator ON facility must use a normally open contact that closes to indicate that a generator is
running and supplying input power to the UPS. It is located at the bottom of the DPA UPSCALE
TM
frame on the communication card with terminal blocks X1 …X2. See chapter 6.4.3 for details.
When used, this facility disables the UPS static bypass and prevents the UPS from transferring the
load onto the generator power supply.
