2.2.2 Operational requirements
CIU 888 is provided with an advanced and efficient cooling system
using a heat pipe. For its operation, it requires ambient temperature,
that is, the temperature around both heat sinks in any type of operation
- desktop, rack mount, or wall mount.
2.3 Mechanical installation
Safety grounding
Pull reliefs (signal cabling)
All M6 (low carbon steel) screws to secure the CIU 888 to the rack
maintain torque values between 3.4 Nm to 4.6 Nm [30.1 lbs-in to 40.7
lbs-in].
2.4 Electrical installation
Check if the fuse is intact.
Check if the Key(s) for the Key Lock Switches are available.
Marking of ports and cables. The CIU 888 is grounded via the earth wire
of the mains cable and an external ground terminal is provided, which is
located at the rear side next to the mains power entry.
2.5 Mounting
You can mount the CIU 888 can in three different ways.
Table top or desktop use
19” rack mount
Wall mount
In any case, the front panel of the CIU 888 must be freely accessible.
The front panel includes the LCD display, user keys, ring of light, service
port, reset switch, key switches, etc., all of which must be freely
accessible.

2.5.3 Wall Mounting
You will need a wall mounting kit for wall mounting CIU 888. f you have
not ordered it from the factory, order it as an accessory. See the
accessory list provided in this manual.
The wall mounting kit consists of the following parts:
Wall Mount Base Plate
Wall Mount Clamps
For accessibility of the front panel and recommendations for cooling
with the heat pipe, follow these recommendations:
The height of the front panel must be suitable enough for you to have
clear visibility and free access of the front panel.
Mount the base plate horizontally so that it ensures that the CIU 888 is
also mounted horizontally.
Follow these steps to mount the unit to the Wall Mount Base Plate:
1. Hold the Wall Mount Base Plate against the wall and make a marking
for the holes. Drill holes and fix the screws in place.
CAUTION! Ensure that the bracket is perpendicular to the floor
and does not tilt sideways.

CHAPTER 3 ELECTRICAL INSTALLATION
3.1 Grounding
CIU 888 is grounded through the earth wire of mains cable and also
through dedicated earth terminal (mandatory) provided on the rear side
of the CIU 888. There are three more earth terminals provided on the
rear side of CIU 888 to connect to earth when bpm communication
channels are engaged.
A 4 mm two single or stranded copper wires are generally accepted by
the safety authorities.
NOTE: The grounding should be performed in accordance with the local regu-
lations.
3.2 Mains
The mains supply for the CIU 888 is 100-240VAC, 50/60 Hz. The power
rating is 60 VA max (35 VA typical). Supply variations of +10% and -
15% are allowed. The power supply unit inside the CIU 888 detects to
which supply it is connected and automatically switches over to the
correct setting.
The mains block contains two fuses one on line and other on neutral
(size: Ø5 x 20 mm), both rated: 1.6 A slow blow (T1.6 A L 250 V) in
accordance with IEC 60127-2/III.
Fuse Details:
• Part#: 0239002.MXP
• Make: Littelfuse
• Description: FUSE 250 V UL SLOBLO 5X20 MM 2A
CAUTION! Check if the mains supply voltage falls within the specified limits of
100-240 VAC.
CIU 888 has been supplied with a C13 plug on the CIU 888 side and
open end wires on the Line socket side. You can install country specific
plug to these open end wires and use it.
The mains switch is located on the rear side of the CIU 888.
NOTE: Always use proper installation material.
NOTE: The mains connection terminal and the external ground terminal must be
grounded, which are available at the rear side of the CIU 888.
