certified Zone 2 enclosure that provides a minimum ingress
protection of IP54 when used in a Zone 2 environment.
2. The enclosure shall only be accessible with the use of a tool.
3. Device shall only be used in an area of not more than pollution
degree 2.
4. Provisions shall be made, external to the apparatus, to provide
the transient protection device to be set at a level not exceeding
140% of the rated voltage at the input terminals of this apparatus.
General installation instructions
1. The NGC-30 components must be installed:
– In compliance with all local electrical and safety codes
– In an enclosure suitable for the application environment.
When used in Zone 2 hazardous locations, a minimum IP54
enclosure is required. The enclosure shall only be accessible
with the use of a tool.
2. The NGC-30 components must be protected by external
overcurrent and disconnect devices. This may be a circuit
breaker or a combination of disconnect switch and fuses. Also
for Overvoltage protection, an external protection needs to
be provided to limit any transients to 140% of the rated input
voltage. The disconnect device:
– Must disconnect all ungrounded, current-carrying conductors
– Should be located in close proximity to the equipment
– Be within easy reach of the Operator
– Be marked as the disconnecting device for the equipment
3. Supply wiring insulation must be rated for the highest voltage
and temperature to be encountered in the application.
Conductors must be sized for the application and be protected
by an external overcurrent device.
4. Some wiring configurations will use more than one power
source and all must be de-energized prior to performing any
maintenance on a controller circuit.
5. Protection provided by this equipment may be impaired if the
device is used outside of its ratings or for applications other than
is intended.
6. Always be sure that the intended location is classified as an area
for which the product is approved.
7. CRM(S) and CTM modules must be handled with care when
installed in a panel. Components should not be subject to
mechanical stress.
8. Wear an anti-static wrist strap connected to ground in order to avoid
component damage when installing the CRM(S) or CTM modules.
Conducted and radiated emissions - Statement of compliance
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 in a residential installation. This equipment
generates, uses and can radiate radio frequency energy and, if
not installed and used in accordance with the instructions, may
cause harmful interference to radio communications. However,
there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to
radio or television reception, which can be determined by turning the
equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from
that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for
help.
This Class A digital apparatus complies with Canadian ICES-003.
