2 Installation
This chapter explains the installation of the ISGS relay and
includes procedures for unpacking, storing, mounting, and
wiring the relay. Prior to installation, ensure that the system
power is off and that you have all required tools and test
equipment available.
2.1 Unpacking
Upon receipt of the relay, inspect the carton for signs of dam-
age. If the carton has been opened or damaged, carefully
inspect and verify the contents against the packing list. If
pieces are missing or damaged, contact the shipping agent
or your Siemens representative. Refer to Figure 2.1 to iden-
tify the different parts of the relay.
Note: To avoid damage to the relay, transport or
store the relay in the original packing mate-
rial. Always transport the cradle assembly
inside the case.

2.2 Storing
Extended storage of the relay should adhere to the following
guidelines:
• Store the relay in a clean, dry location in the original
packing material
• Storage temperature range is -40°F to +167°F
(-40°C to +75°C)
Note: This device contains electrolytic capacitors,
which can degrade over time when stored
at temperatures over 86°F (30°C). Take care
not to store the relay at high temperatures
for extended periods.
After extended storage, connect the relay to its auxiliary volt-
age source for one or two days prior to taking it into actual
service. This serves to regenerate the electrolytic capacitors
of the auxiliary supply.
2.3 Mounting
The ISGS relay is typically installed in a switchgear unit or
relay panel. The required panel opening and a side view of
the relay are shown in Figure 2.2.
