2 RECEIVING AND STORAGE
2.1 Receiving
All possible precautions are taken to protect the equipment against damage or losses during shipment,
however, before accepting delivery, check all items against the packing list or bill of loading. If there are
shortages or evidence of physical damage, notify Ampcontrol immediately.
Notify Ampcontrol immediately in the case of any discrepancies to the packing list. Keep a record of any
claims and correspondence. Photographs are recommended.
Where practicable do not remove protective covers prior to installation unless there are indications of
damage. Boxes opened for inspection and inventory should be carefully repacked to ensure protection
of the contents or else the parts should be packaged and stored in a safe place. Examine all packing
boxes, wrappings and covers for items attached to them, retain and store any approval documentation
for your safety file as applicable prior to wrapping being discarded.
2.2 Inspection
Equipment that is found to be damaged or has been modified away from its published specification must
not be used. Please contact Ampcontrol if the equipment is suspected to be different than that ordered or
if it does not match the published specifications.
2.3 Storage after Delivery
2.3.1 General Storage Requirements
When the equipment is not to be installed immediately, proper storage is important to ensure protection
of equipment and validity of warranty.
All equipment should be stored indoors, in a cool dry environment, on raised shelves, and protected from
the elements. Ensure that the storage area is not an area where water will collect.
2.3.2 ISUPS Battery Care
The storage period should be as short as possible. Temperature has an impact on the self-discharge
rate hence it is important to store the batteries in a fully charged condition in a cool but frost-free room.
The batteries will be delivered fully charged and installed inside the enclosure. The battery is non-
serviceable and non-user replaceable.
WARNING!
DO NOT ATTEMPT TO REMOVE THE BATTERIES FROM THE
ENCLOSURE
The ISUPS has no internal user-serviceable parts. All repairs must
be carried out by Ampcontrol personnel only. If a fault develops return
the ISUPS to Ampcontrol for repair. It is essential that no attempt be
made to repair the UPS as any attempt to dismantle or repair the UPS
can seriously compromise the safety and correct operation of the unit.

ISUPS2B004 R2 –DEC/17
The maximum storage time at ≤ 20°C is 12 months. Higher temperatures cause higher self-discharge
and shorter storage time between recharging operations.
If it is anticipated that the UPS will not be used and will remain disconnected from the mains power
supply for a period of time exceeding the recommended maximum, the battery should be recharged
before the maximum period is reached or the batteries could be permanently damaged.
We recommend re-charging the 300Wh ISUPS every 6 months while in storage.
To recharge the battery in this situation, connect a lead with mains plug to the unit’s AC input terminals.
Supply should be 90 ~ 250VAC. Turn the power on for the “Charging Time” as listed in Section 13,
Specifications.
2.4 Unpacking of Equipment
The method of packing used will depend on the size and quantity of the equipment. The following
cautions should be interpreted as appropriate.
CAUTION!
Take care when unpacking crates as the
contents may have shifted during transport.
ENVIRO
The disposal of packaging materials, replaced parts, or components
must comply with environmental restrictions without polluting the soil,
air or water.
Ensure that any timber and cardboard used as packaging is disposed
of in a safe and environmentally responsible manner.
Where possible, dispose of all waste products i.e. oils, metals, plastic
and rubber products by using an approved recycling service centre.

3 PRODUCT OVERVIEW
The 300Wh V2 Intrinsically Safe Uninterruptible Power Supply (ISUPS 2) by Ampcontrol is designed for
Group I applications. The ISUPS converts 90 ~ 250VAC mains power into intrinsically safe low voltage
DC power with a built-in Battery Backup. A user accessible keypad, LCD screen, and indicator lamps
allow interrogation and configuration of the ISUPS. The ISUPS also provides several other intrinsically
safe monitoring and control connections.
3.1 Key Features
LCD Display with Keypad input
“Mains On”, “Output On” and “Output Overload” indicator LED’s
“Stop LED” and “Reset LED”
Local start/stop
Remote start/stop
Auto shutdown on low battery
Battery state and capacity indicators
Configurable alarms for:
oOutput over current
oOutput under current
oOutput under voltage
oBattery over temperature
Three output relays with voltage free NO contacts. These can be configured for multiple alarm
functions. Contacts are rated at 30V/3A.
Relay 1 is suitable for use with a separate intrinsically safe circuit i.e. the contact is isolated from
the UPS intrinsically safe circuit.
Relays 2 and 3 are suitable for use on the same intrinsically safe circuit (i.e. not isolated from
each other) that may be separate to the IS circuits of the UPS or those utilised on Relay 1
Two external isolated digital inputs (DI2, DI3) that may be used to activate functions as listed in
Table 6. These can be powered from a common external intrinsically safe circuit or the ISUPS
output.
A non-isolated digital input (DI1) that can be configured to activate functions as listed in Table 6
Modbus RTU over RS485 communications port to monitor the device
Event and periodic logs
User configurable timer to shut-down the UPS, while operating from battery
This ISUPS must be installed in an upright position and may be mounted by its back or base using M6
screws. The enclosure is of a robust stainless steel construction with screw connection terminals inside
internal connection boxes on top of the enclosure. The ISUPS has two separate connection
compartments to isolate the incoming AC power from the various Intrinsically Safe Circuits.
CAUTION!
The AC power terminal compartment should only be opened if the
external AC supply has been de-energised. Opening this
compartment in a hazardous area when the AC supply is energised is
not permitted.
WARNING!
THE MAINS VOLTAGE COMPARTMENT MUST NOT BE OPENED
WHEN AN EXPLOSIVE ATMOSPHERE IS PRESENT.

All cables enter and exit the enclosure via appropriate cable glands. The cable glands must meet a
minimum requirement of IP66 to maintain the integrity of the enclosure. If the ISUPS is to be installed in
a Zone 1 environment, then the gland used on the incoming AC supply will need to be certified to ‘Ex d’
or ‘Ex e’.
NOTE
Cable glands into the ISUPS enclosure must be a minimum of IP66. If
the enclosure is going to be installed in Zone1, then the AC Mains gland
must be rated to ‘Ex d’ or ‘Ex e’.
Typical use of this power supply is for gas detection systems but it is also suitable for voice
communication systems, serial to Ethernet converters, and other electronic equipment requiring
intrinsically safe power in Group I applications. The Intrinsically Safe UPS can be used as a simple
backup system for IS circuits in line with the output parameters and the factory default configuration or
can be user configured with optional functions.
The user can configure various functions of the UPS, as well as the use of the external I/O which
includes 3 digital inputs, 3 relay contacts and Modbus communications.
WARNING!
The UPS has no internal user-serviceable parts. All repairs must be
carried out by Ampcontrol personnel only. Should a fault develop, return
the ISUPS to Ampcontrol for repair. It is essential that no attempt be
made to repair the UPS as any attempt to dismantle or repair the UPS
can seriously compromise the safety of the unit and the consequence
can be fatal.
