Commissioning - EnerSys Nexsys 12NXS26 Technical Manual

The bloc has a maximum inspection-free storage life of 2 years, if stored at or below
20°C/68°F, after which a refresh charge should be administered. However, it is advisable to
conduct an inspection and open circuit voltage check after 12 months. If the open circuit
voltage falls below 12.6 volts the bloc should be recharged using an approved EnerSys®
NexSys® charger.

COMMISSIONING

The NexSys series monoblocs are supplied in a charged condition. The bloc should be
inspected to ensure it is in perfect physical condition.
Check:
1.The bloc cleanliness. Before installing, the bloc compartment has to be cleaned.
2.All cables and crimped connectors are in good condition to support high electrical
currents.
3.The bloc and cables have a good contact to terminals and the polarity is correct.
Otherwise the bloc, vehicle or charger could be severely damaged.
4.Ensure that all insulation covers are fitted correctly.
5.It is extremely important to ensure the integrity of bloc connections. Soldered
connections are preferred for bloc plugs and post clamps. If soldering is not possible,
multi-point crimping must be used.
NOTE: Flexible cable or braid connectors must be used for all monobloc connections.
Appropriate fastener kits must be used and approved parts. These can be supplied in
EnerSys approved accessory kits. Integral to the fasteners system is an appropriate locking
washer – spring or flat washers must not be used.
Connectors must be adequately fastened (see Table 3) with the locking washer in place to
maintain contact integrity when exposed to operational shock/vibrations.
