General

1.1 Introduction

The microcontroller controlled battery chargers of the
BC 800 R series are designed for wall mount and work
with an airflow based cooling.
They are intended to charge different types of lead
batteries. The three-stage, temperature compensating
charging procedure allows fast, complete and careful
charging of the batteries.
Furthermore, the devices feature a power supply mode
where the output voltage becomes adjustable.
The power output is protected against false polarity
connection, is short-circuit-proof and overload-proof.
For protection of the loads, the devices also feature an
overvoltage protection (OVP). At an overtemperature
(OT) event, the power output will be switched off until
the unit has cooled down and automatically switch on
again.

1.2 Visual check

After receipt, the unit has to be checked for signs of
physical damage. If any damage is found, the unit may
not be operated. Also contact your dealer immediately.

1.3 Replacing the internal fuse

Note: does not apply to model BC 812-40 R, because
here the fuse is located in a fuse holder on the front.
The main fuse is located inside the device. Before ope-
ning the device, completely disconnect it from mains.
Working on the open device must only be done by
trained technical personnel which is instructed about
the dangers and safety regulations.
In order to replace the fuse, unscrew the front cover
plate and remove it precautiously. The fuse is located
on the main PCB, on the left-hand side.

Installation

2.1 Mounting

The device is designed for wall mount. It is required to
mount it in a way that allows unimpeded air flow through
the ventilation slots. Take care for plenty of space (at
least 15cm) below and above the device in order to
ensure proper cooling.

2.2 Mains connection

All models are equipped with an active PFC (power
factor correction) and a wide range input. It can be
operated at AC input voltages from 90V to 264V and
mains frequencies of 45Hz up to 65Hz.
The connection is done with the included 3-pole plug
(Phoenix Combicon GMSTB 2,5/3-ST-7,62) according
to the print on the front plate. It must only be carried
out by trained technical personnel. Main focus lies on
an appropriate cross section of the mains lead, as well
as the fact that the device does not feature a power
switch. The mains input is fused by a standard 5x20mm
fuse which is located inside the unit.

2.3 DC output and sense connection

The DC output for the battery conection and the remote
sense inputs are located on the front. Except for model
BC 812-40 R, these are all of the same type (press &
clamp). Cable cross section goes from 0.08mm² (28
AWG) to 4mm² (12 AWG). If possible, use cable end
sleeves.
Clamping procedure:
With model BC 812-40 R, the battery is connected via
screw terminal
