PREFACE
Welcome to the Operator’s Handbook for the Oxford Instruments NanoScience MercuryiPS
cryogenic environment controller. The MercuryiPS is a high performance laboratory magnet
power supply, with a number of features specifically intended for use in cryogenic applications
as required for superconducting magnets.
Use of this manual
This Operator’s Handbook provides all the information necessary for the safe and proper
installation, operation and servicing of the MercuryiPS magnet power supply.
Chapters 1 to 5 provide essential information that must be read and understood before
operating the MercuryiPS for the first time.
Intended users
Users of the MercuryiPS must have received adequate training on its safe and effective use
before attempting to work with the equipment. Please contact Oxford Instruments NanoScience
for information on training requirements and training courses that are available.
Training requirements vary from country to country. Users must ensure that training is given in
accordance with all applicable local laws and regulations.
If any user of the equipment has not been directly trained by Oxford Instruments NanoScience,
ensure that they understand the safety issues associated with the equipment, and that they
consult relevant personnel for guidance when operating the equipment.
Statement of intended use of the MercuryiPS
The MercuryiPS has been designed for superconducting magnet control. The equipment has
been designed to operate within the process parameter limits that are outlined in this manual.
The MercuryiPS is intended to be installed, used and operated only for the purpose for which
the MercuryiPS was designed, and only in accordance with the instructions given in this
manual and other accompanying documents. Nothing stated in this manual reduces the
responsibilities of users to exercise sound judgement and best practice.
It is the user's responsibility to ensure the system is operated in a safe manner. Consideration
must be made for all aspects of the system's life-cycle including, handling, installation, normal

operation, maintenance, dismantling, decontamination and disposal. It is the user's
responsibility to complete suitable risk assessments, to determine the magnitude of hazards.
The installation, use and operation of the MercuryiPS are subject to laws in the jurisdictions in
which the equipment is installed and in use. Users must install, use and operate the equipment
only in such ways that do not conflict with said applicable laws and regulations.
If the equipment is not installed, used, maintained, refurbished, modified and upgraded as
specified by the manufacturer, then the protection it provides could be impaired. Any resultant
non-compliance, damage, or personal injury would be the fault of the owner or user.
Use of the equipment for purposes other than those intended and expressly stated by Oxford
Instruments NanoScience, as well as incorrect use or operation of the equipment, may relieve
Oxford Instruments NanoScience or its agent of the responsibility for any resultant non-
compliance, damage or injury. The system must only be used with all external panels fitted.

1 HEALTH AND SAFETY
This chapter describes all health and safety considerations relating to the Oxford Instruments
NanoScience MercuryiPS magnet power supply.
The following safety precautions must be observed during the operation, service and repair of
this instrument.
1.1 Warnings
Before you attempt to install or operate this equipment for the first time, please make sure that
you are aware of the precautions that you must take to ensure your own safety.
1.1.1 Protective and functional ground
The equipment must be connected to an electrical ground. The ground wire (green/yellow) in
the equipment power cable must be connected to the electrical ground system of the
installation.
Only use extension cords that have a protective ground conductor.
Do not disconnect the protective ground connection inside or outside the equipment.
Do not connect external electrical circuits to the equipment if its protective ground is
disconnected.
There is a ground pillar on the rear panel, identified by a symbol. This should be used to
connect the cryostat chassis (or the experiment rig chassis if not a cryostat) to ensure the
cryostat (or alternative chassis) is grounded.

1.1.2 High voltage hazard
HIGH VOLTAGE
Danger of death or serious injury. Switch off the external AC
electrical supply and disconnect and remove the external supply
cable, before maintaining this equipment or removing any covers.
HAUTE TENSION
Danger de mort ou de blessure grave. Sectionner l'alimentation
électrique C.A. externe puis déconnecter et retirer le cordon
d'alimentation externe avant d'effectuer toute maintenance de cet
équipement ou d'en retirer les capots.
This equipment contains high voltages. Isolate this equipment before removing the screws and
covers. To isolate this equipment, switch off the external AC electrical supply, and disconnect
and remove the external supply cable. Do not restrict access to the AC electrical supply at any
time. The AC electrical supply cable must remain accessible for disconnection of the equipment.
1.1.3 Maintenance and adjustment
Only qualified and authorised persons must service or repair this equipment.
Under no circumstances must the user adjust or repair this equipment while the electrical power
supply is connected.
Ensure that the equipment is disconnected from the AC electrical power supply before the
covers are removed. It is NOT sufficient to turn off the unit from the power-down button on the
front panel. It is also NOT sufficient to turn off the mains power switch on the rear
panel. The unit MUST be disconnected from the mains supply. Also, the equipment contains
capacitors that may remain charged after AC electrical power is removed. Wait at least 15
minutes after disconnecting the mains supply to ensure all the capacitors are discharged before
starting work.
1.1.4 Restrictions on use
The equipment is not suitable for use in explosive, flammable or hazardous environments.
The equipment does not provide protection against the ingress of water. The equipment must
be positioned so that it will not be exposed to water ingress.
