If UL/cUL is to be complied with, copper cable with temperature class 60/75°C / 140/167°F must be used
(VLT 8002 - 8072 (525 - 600 V), VLT 8006 - 8072 (380 - 480 V) and VLT 8002 - 8032 (200 - 240V). If
UL/cUL is to be complied with, copper cable with temperature class 75°C/167°F must be used (VLT 8102
- 8652 (380 - 480 V), VLT 8042 - 8062 (200 - 240 V), VLT 8052 - 8652 (525-690 V)).
Connectors are for use of both copper and aluminium cables, unless other is specified.
