CSA Certified 3 - conductor, [18 AWG], terminated in a molded on plug cap rated 125 V, [5
A], with a minimum length of 1.5m [six feet] but no longer than 4.5m.
Special Notices for European Users:
For European connection, select a power supply cord that is internationally harmonized and
marked “<HAR>”, 3 - conductor, 0,75 mm2 minimum mm2 wire, rated 300 V, with a PVC
insulated jacket. The cord must have a molded on plug cap rated 250 V, 3 A.
Interconnection Cabling:
Cables for connecting to the unit's RS232 and Ethernet Interfaces must be UL certified type
DP-1 or DP-2. (Note: when residing in non-LPS circuit)
Overcurrent Protection:
A readily accessible listed branch-circuit overcurrent protective device must be incorporated
in the building wiring for the power input as follows:
