3. Safety and EMC Information

This controller is intended for industrial temperature and
process control applications when it will meet the
requirements of the European Directives on Safety and
EMC. Use in other applications, or failure to observe the
installation instructions of this handbook may impair safety
or EMC. The installer must ensure the safety and EMC of
any particular installation.

Safety
This controller complies with the European Low Voltage
Directive 73/23/EEC, by the application of the safety
standard EN 61010.

Electromagnetic compatibility
This controller conforms with the essential protection
requirements of the EMC Directive 89/336/EEC, by the
application of a Technical Construction File. This instrument
satisfies the general requirements of the industrial
environment defined in EN 61326. For more information on
product compliance refer to the Technical Construction File.

GENERAL

The information contained in this manual is subject to
change without notice. While every effort has been made to
ensure the accuracy of the information, your supplier shall
not be held liable for errors contained herein.

Unpacking and storage
The packaging should contain an instrument mounted in its
sleeve, two mounting brackets for panel installation and an
Installation & Operating guide.
If on receipt, the packaging or the instrument are damaged,
do not install the product but contact Super Systems, Inc. If

SERVICE AND REPAIR

C.

This controller has no user serviceable parts. Contact Super
Systems, Inc. for repair.

Caution: Charged capacitors
Before removing an instrument from its sleeve, disconnect
the supply and wait at least two minutes to allow capacitors
to discharge. It may be convenient to partially withdraw the
instrument from the sleeve, then pause before completing
the removal. In any case, avoid touching the exposed
electronics of an instrument when withdrawing it from the
sleeve.
Failure to observe these precautions may cause damage to
components of the instrument or some discomfort to the
user.

Electrostatic discharge precautions
When the controller is removed from its sleeve, some of the
exposed electronic components are vulnerable to damage by
electrostatic discharge from someone handling the
controller. To avoid this, before handling the unplugged
controller discharge yourself to ground.

Cleaning
Do not use water or water based products to clean labels or
they will become illegible. Isopropyl alcohol may be used to
clean labels. A mild soap solution may be used to clean
other exterior surfaces of the product.

Installation Safety Requirements

Safety Symbols
Various symbols may be used on the controller. They have
the following meaning:

Helpful hints

Personnel
Installation must only be carried out by suitably qualified
personnel in accordance with the instructions in this
handbook.

Enclosure of Live Parts
To prevent hands or metal tools touching parts that may be
electrically live, the controller must be enclosed in an
enclosure.

Caution: Live sensors
The controller is designed to operate if the temperature
sensor is connected directly to an electrical heating element.
However you must ensure that service personnel do not
touch connections to these inputs while they are live. With a
live sensor, all cables, connectors and switches for
connecting the sensor must be mains rated.

Wiring
It is important to connect the controller in accordance with
the wiring data given in this guide. Take particular care not
to connect AC supplies to the low voltage sensor input or
other low level inputs and outputs. Only use copper
conductors for connections (except thermocouple inputs)
and ensure that the wiring of installations comply with all
local wiring regulations. For example in the UK use the
latest version of the IEE wiring regulations, (BS7671). In the
USA use NEC Class 1 wiring methods.

Power Isolation
The installation must include a power isolating switch or
circuit breaker. This device should be in close proximity to
the controller, within easy reach of the operator and marked
as the disconnecting device for the instrument

.

Overcurrent protection
The power supply to the system should be fused
appropriately to protect the cabling to the units.
