source of power except the CloudLink 5G.
e. P13 shall only be used in a non-hazardous area for factory settings only. Um max ≤ 12V.
f. The CloudLink 5G shall only be powered by an associated apparatus meeting the parameters
defined (P1 or P2) OR the following battery packs:
Nomenclature variants: Allowed battery pack
i. 51308889-276: Mercury 40-6197 (7.2V)
ii. 51308889-476: Elster 73021211 (3.9V)
The battery packs shall not be replaced in a hazardous area, and be protected from mech-
anical impact in the end application.
For EPL Gc application:
a. The CloudLink 5G shall only be used in an area of at least pollution degree 2, as defined in
IEC 60664-1.
b. The CloudLink 5G shall be installed in a suitable enclosure that provides a minimum ingress
protection of IP54 in accordance with IEC 60079-0, unless the equipment is afforded an equi-
valent degree of protection by location.
c. Transient protection shall be provided that is set at a level not exceeding 140% of the peak
rated voltage value of the source terminals to the equipment.
d. The CloudLink 5G does not have any surface that exceeds 135°C at a maximum ambient tem-
perature of +70°C. The service temperature inside the end enclosure shall not exceed the tem-
perature range specified for this component.
e. The SIM connection shall only be used for SIM card. The SIM card may be connected or dis-
connected in a Hazardous area.
f. J2 shall only be used for a passive antenna with no additional inductance and capacitance.
The length of the cable to this antenna shall not exceed 1m. The maximum RF power shall
not exceed 3.5W, and the maximum RF energy (Zth) shall not exceed 250μJ when an external
antenna is used with CloudLink 5G. Furthermore, the external antenna shall not have another
source of power except the CloudLink 5G.
g. The integration interface (J4 for 51308889-476 and P8 for 51308889-276) shall be mech-
anically restrained in the assembly/end product according to the manufacturer’s spe-
cifications per Installation Drawing 40-6221.
h. The CloudLink 5G shall only be powered as below based on Model nomenclature:
i. 5 Vdc – 15 Vdc (51308889-276 and 51308889-476)
ii. Battery pack 40-6154 (7.2V) for 51308889-276 only
The battery pack shall not be replaced in a hazardous area, and be protected from
mechanical impact in the end application.
