1. Introduction
Single Unit
The Battery Pack Charger can be installed as a single unit.
Multiple Units
A number of Battery Pack Chargers and Charging Racks may be connected together.
Maximum five units may be connected. An installation with multiple units requires a fixed
electrical installation.
NOTE: In the USA and Canada the Battery Pack Charger must only be installed as a single
unit. Connection of several units is not permitted.
1.1 Safety
•It is not allowed to supply more than one unit by the power cord with the C14 connector.
• The safety covers on top of the supply voltage terminal blocks must be mounted to
prevent hazardous situations, like electric shock.
• When servicing the unit, the power cord must be disconnected.
• For permanently connected equipment, a readily accessible disconnect device shall be
incorporated in the building installation wiring. The disconnect device shall disconnect
both poles.
• For pluggable equipment, the wall outlet shall be installed near the equipment and shall
be easily accessible.
In Sweden, Norway and Finland the unit must be connected to protective earth (safety
grounding). For other countries it is recommended to use a protective earth connection.
• Suomi: Laite on liitettävä suojamaadoituskoskettimilla varustettuun pistorasiaan.
• Norge: Apparatet må tillkoples jordet stikkontakt.
• Sverige: Apparaten skall anslutas till jordat uttag.
