FCC and EMC declarations of compliance
United States
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a
commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in
accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a
residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own
expense.
Canada
This digital apparatus does not exceed the Class A limits for radio noise emissions from digital apparatus set out in the Radio
Interference Regulations of the Canadian Department of Communications.
Le présent appareil numérique n’émet pas de bruits radioélectriques dépassant les limites applicables aux appareils numériques de
la Classe A prescrites dans le Règlement sur le brouillage radioélectrique edicté par le ministère des Communications du Canada.
Installation
NO USER SERVICEABLE PARTS. REFER TO QUALIFIED SERVICE
PERSONNEL FOR SERVICE.
The power connection must be made in accordance with the state and or country
regulations.
Make sure that the voltage rating printed on the ID rating plate is identical to that of
your incoming voltage.
Protection Class 1 Device; The device must be plugged into a properly installed
outlet that has a protective grounding conductor.
.
If you use an electrical outlet that does not have the grounding conductor, ensure
that the equivalent grounding conductor is installed by a certified electrician.
Safe handling of equipment with batteries
CAUTION: Danger of explosion if battery is incorrectly replaced. Replace only
with the same or equivalent type recommended by the manufacturer. Dispose
of used batteries according to the manufacturer’s instructions.
ATTENTION: Il y a danger d'explosion s'il y a remplacement incorrect de la
batterie, remplacer uniquement avec une batterie du même type ou d'un type
équivalent recommandé par le constructeur. Mettre au rebut les batteries
usagées conformément aux instructions du fabricant.
Wet conditions
Under wet conditions, the plug must be connected to the final branch circuit via an
appropriate socket / receptacle designed for washdown use.
Installations within the USA should use a cover that meets NEMA 3R specifications
as required by the National Electrical Code under section 410-57. This allows the unit
to be plugged in with a rain tight cover fitted over the plug.
Installations within Europe must use a socket which provides a minimum of IP56
protection to the plug / cable assembly. Care must be taken to make sure that the
degree of protection provided by the socket is suitable for the environment.
Maintenance
IMPORTANT: This equipment must be routinely checked for proper operation
and calibration.
Application and usage will determine the frequency of calibration required for
safe operation.
Always isolate the indicator from the power supply before starting any routine
maintenance to avoid the possibility of electric shock.
Cleaning the machine
Cleaning DOs and DON’Ts

Front panel
Front panel of the ZM155 indicator
Never press a key with anything but your finger. Damage to the overlay may result if
sharp or rough objects are used.
1. The front panel of the intrinsically safe ZM155 indicator is non-metallic and shall
should not be used where UV light or radiation may have an impact on the
enclosure.
2. The front panel of the intrinsically safe ZM155 indicator is non-conducting and
under certain extreme conditions may generate an ignition capable level of
electrostatic charges. The user shall ensure that the equipment is not installed in a
location where it may be subjected to external conditions (such as high-pressure
steam) which might cause a build-up of electrostatic charges on non-conducting
surfaces. Additionally, cleaning of the equipment should be done only with a damp
cloth.
3. The device shall be installed in such a way that it is protected against the entry of
solid foreign objects or water capable of impairing the safety of the apparatus.
Reduce the risk of mechanical damage to a minimum,
4. After the first installation, the gasket must be replaced each time the enclosure is
opened.
