4.2. Electrical Installation
4.2.1. Health and Safety for Electrical Installation
Read and observe chapter
1. 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.
2. Danger: Electrical hazard. Danger of death or fatal injury from electrical
current inside the unit in operation. Before opening the unit, disconnect mains
power.
4.2.2. Property Damage Warnings for Electrical Installation
1.
Attention:
It is compulsory to ground (earth) the unit before connecting the power
supply. A grounding bolt is provided on the cabinet to connect the ground-bonding
cable.
2.
Attention:
The BBU/UPS must be installed within easy reach and it must be
equipped with a disconnect device.
3.
Attention:
Before connecting or disconnecting the BBU at/from the PSR, ensure
that the BBU/UPS is not connected to the mains power supply.
4.
Attention:
Make sure that an appropriate circuit breaker acting as a disconnect
device (as required by NEC, NFPA 70) and an overcurrent limiting device are
connected between mains power and the PSR.
5.
Attention:
Incorrectly wired
connections
can destroy electrical and electronic
components.
6.
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).
7.
Notice:
Use an appropriate torque wrench for the coupling torques:
for 4.3-10 type connectors (5 Nm, 44 in lb) with 22mm (7/8) in opening,
e.g. item no. TW-4310
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 PSR.
8.
Notice
:
For unstabilized electric networks, which frequently generate spikes, the
use of a voltage limiting device is advised.
9.
Notice:
Observe the labels on the front panels before connecting or disconnecting
any cables.
10.
Notice:
Unused connectors must be closed with their protective covers to ensure
watertightness.
11. Check all cables for shorts and opens. Verify that there are no cables with loose or
poor connections. RF leakage could cause oscillation to occur under some
conditions.
