1.
Attention:
It is compulsory to ground (earth) the unit before connecting the power
supply. Grounding bolts are provided on the cabinet to connect the ground-bonding

2.
Attention:
If the mains connector of the Remote Unit is not easily accessible, a
disconnect device in the mains power circuit must be provided within easy reach.
3.
Attention:
A connection of the mains supply to a power socket requires the power
socket to be nearby the Remote Unit.
4.
Attention:
Before connecting or disconnecting the mains connector at the Remote
Unit, ensure that mains power supply is disconnected.
5.
Attention:
Make sure that an appropriate circuit breaker acting as a disconnect
device (as required by IEC/EN60950-1) and an overcurrent limiting device are
connected between mains power and the Remote Unit.

Attention:
Incorrectly wired connections can destroy electrical and electronic
components.
7.
Notice:
To avoid corrosion at the connectors caused by electrochemical
processes, the material of the cable connectors must not cause a higher potential
difference than 0.6 V (see electrochemical contact series).
8.
Notice:
Use an appropriate torque wrench for the coupling torques:
- for 4.3-10 type connectors (5 N-m, 44 in lb) with 22mm (7/8) in opening,
