11.2 Product De-rating
Table 7.1 shows the maximum permissible load for a specified Ambient operating
environment. These maximum ratings should never be exceeded, as the safety of the
system will be compromised.

Table 7.1
*After running for approximately 20mins at full load above 20ºC, the
max output power available can reduce by up to 15%
The reason this happens is to stop the inverter overheating when running at full load
in high ambient. The output power is reduced slightly to allow the UPS to continue
running and backing up loads. Continued operation at full load may cause the system
to shut down to prevent damage, therefore losing all power to the connected
equipment.
Important! Users must ensure they do not exceed the ratings shown in Table 7.0. If
the system is operated outside these values, but within those shown on
the rating plate / ATEX certificate, then it is possible the UPS may limit
the amount of power available at the Output to protect against thermal
overheating, or blow a fuse within the Ex ‘d’ enclosure.
Important! Although the iUPS101 rating label states T6, the complete assembly is
only rated at T5 due to the certification of the terminal box
11.3 Replacement Parts
Extronics hold a range of replacement components available for same / next day
dispatch. Should you require any replacement parts, or technical help please contact
Extronics.
The iUPS101 is supplied with spare protection fuses which the user can replace in
the event of a system overload. Please see chapter 3.4 of this manual.
For continuous operation of critical high availability systems, users are advised to
implement a ‘redundant’ iUPS101 - this will ensure vital equipment is permanently
operational in the unlikely event of a failure.
Fitted internally to the Ex ‘d’ enclosure is a coin cell replacement PCB + Coin cell for
the purpose of electronic memory retention (Extronics Drawing / Part No. 331072).
Should this need replacing, please contact Extronics for further information.
