4.1.1
Required tools
• Electrical connection A
- Connection terminals: Head screwdriver 1.2 x 8.0 mm
- Connection head: Head screwdriver 1.0 x 6.0 mm
- Cable gland: Open-end wrench 17 mm (AF)
• Electrical connection D and G: depends on the connector used by the customer
4.1.2
Connecting cable requirements
The customer-supplied connection cable for the electrical connection A (connection head
with terminals and cable gland) must meet the following requirements:
• Permissible temperature range -20 ... +70°C (-4 ... +158°F)
• Standard installation cable
