INTRODUCTION
The Coldface EWRC 300/500/5000 NT series controls the temperature of a static or ventilated cold
room. The instrument controls positive and negative cold rooms and is capable of managing a double
evaporator and condenser probes.
Coldface has 3 or 5 configurable relays, depending on the model, and 2(3) configurable digital inputs
for door switches or other devices. Models are available with clock with yearly calendar and HACCP
event logging.
It is possible to connect the instrument to TelevisSystem / Modbus via the optional RS485 plug-in
module.
The container lets you install one or more electromechanical devices, depending on the model.
This summary document contains basic information about the standard
EWRC 300/500/5000 NT models. For further information and different configurations, refer to
the complete user manual cod. 9MA*0258 which is available to download free of charge from
www.eliwell.com.
INSTALLATION PROCEDURE
NOTE: procedural steps that are common to all models. Only the EWRC 5000 model is used as an
example.

3) Fix the back of the panel to the wall using four screws (not supplied) suited to the wall thickness.
NOTE: apply TDI20 screw caps (not provided) on 300/500 models.
4) Fit the hinges to secure the cover.
EWRC 5000
Place the panel cover up against the wall, making it
stick to the perimeter seal. Then, while holding the
cover in place, fit the two hinges provided into the
corresponding holes and press them until you hear
them click into place.
EWRC 300/500
Fit the hinges provided into their housings on
the right or left side of the panel and tighten the
corresponding screws to secure them.
5) Close the cover and secure it with the screws
provided.

DANGER
RISK OF ELECTRIC SHOCK, EXPLOSION OR EXPOSURE TO ACCESSIBLE PARTS
The final application must disallow access to parts at hazardous voltage, as the instrument offers no intrinsic
protection against this risk.
Failure to follow these instructions will resultin death or serious injury.
6) DIN rail-mounted models with window only.
Use the dedicated plugs (code 1602149)
to prevent access to the inside of the panel
through the front window.
For EWRC NT 500 models with the plastic
knockout removed and no internal circuit
breaker, the end user is responsible for
ensuring that the open parts of the box are
not accessible.
7) EWRC 5000 only. Fit the door: align the front
door with the two hooks at the bottom of the
panel and push it towards the right until it
clicks into place.
8) Close the door.
