3.2.1. Health and Safety for Electrical Installation
Read and observe chapter 1.2.
Danger: Electrical hazard. Danger of death or fatal injury from electrical current.
Obey all general and regional installation and safety regulations relating to
work on high voltage installations, as well as regulations covering correct use
of tools and personal protective equipment.
3.2.2. Property Damage Warnings for Electrical Installation
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
cable.
2. Attention: If the mains connector of the 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 unit.
4. Attention: Before connecting or disconnecting the mains connector at the 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 unit.
6. Attention: Incorrectly wired
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 N-type connectors (2 N-m / 20 in lb) with 13/16 in opening,
e. g. item no. 244379 available from the CommScope e-catalog
-
for 7/16 DIN-type (25 N-m / 19 ft lb) with 1 ¼ in opening,
e. g. item no. 244377 available from the CommScope e-catalog
SMA connectors have a specified torque of 60 N-cm.
Do NOT use your hands or any other tool (e.g. a pair of pliers). This might cause
damage to the connector and lead to a malfunction of the unit.
9. Notice: For unstabilized electric networks, which frequently generate spikes, the use
of a voltage limiting device is advised.
10. Notice: Observe the labels on the front panels before connecting or disconnecting
any cables.
11. Notice: Unused connectors must be closed with their protective covers to ensure
watertightness.
