2. Insert the relay card into the UPS.
a) Remove the Intellislot port cover (see Figure 3-6) on the front panel. Do not throw the screws away.
b) Align the relay card with the Intellislot port, insert the relay card into the port along the grooves on both sides of
the port.
c) Secure the relay card in place through the fixing holes on the relay card panel using the screws from step a).
3. Connect the cable.
You can select an optional cable according to your needs, or prepare your own, in accordance with Table 8-4 and
Figure 8-10 - Figure 8-12. Connect the cable end with the DB25 male connector to the DB25 connector of the relay
card, and the other end to the user equipment.

The relay car
d is hot
-
pluggable, therefore it may be
installed without shutting the UPS down.
The DB25 connector must be connected to a SELV circuit. Failure to observe this could damage the relay card and even
lead to accidents.
We
recommend usin
g shielded cables in order to increase EMC.
